  • Impact of Bay of Bengal Systems on India’s Monsoon

    Fresh monsoon activity may soon spread across large parts of east and central India. Weather systems are beginning to form over the Bay of Bengal. Forecasters expect the next seven to 10 days to become an important phase for the Southwest Monsoon. Several low-pressure systems may develop and move inland.

    A long zone of atmospheric convergence has formed. It stretches from the Bay of Bengal towards the western Pacific. Such zones can help organised weather systems develop. They bring together moisture-laden winds. Therefore, conditions become more favourable for low-pressure areas.

    Several low-pressure systems may emerge along this zone. They could move westward toward central India over the next five to seven days. As these systems travel inland, they may trigger widespread showers across eastern and central regions. This rain could help areas that have remained deficient during the monsoon season.

    The first half of September may decide the season’s final outcome. Rainfall in this period could change the overall monsoon numbers. Forecasters say a swing of about 5 percent above or below current levels is still possible. That shift will depend on how active the monsoon becomes.

    Rainfall so far in the 2026 Southwest Monsoon has been uneven. Ladakh has recorded the largest surplus at 204 percent above normal. Dadra and Nagar Haveli and Daman and Diu have seen a 51 percent surplus. Odisha is 25 percent above normal. Delhi has also received 18 percent excess rainfall.

    Several states still face large deficits. Meghalaya has the sharpest shortfall at 58 percent below normal. Manipur is 43 percent below normal. Bihar is 42 percent below normal. Arunachal Pradesh and Andhra Pradesh are both around 40 percent below normal.

    India as a whole has received 587.8 mm of rainfall. The normal amount for this period is 679.5 mm. This leaves a seasonal deficit of 13 percent. Despite the shortfall, the monsoon still falls within the India Meteorological Department’s normal rainfall category.

    The developing Bay of Bengal systems may now play a decisive role. Rainfall in early September could also shape the final picture. Together, these factors may determine how the 2026 monsoon season ends.

  • New Google Play Rules for Android Apps: Memory and Sign-In Changes

    Google is changing its requirements for Android apps. Developers already face memory chip shortages across the industry. Strong demand from AI data centres is tightening supply. Therefore, Google wants apps to use device memory more carefully.

    The company has announced two new app quality rules on Google Play. One rule focuses on reducing memory use. The other rule aims to improve sign-in during device migrations. Developers who fail to comply may face clear consequences.

    Raghavendra Hareesh Pottamsetty, GM of Google Play Developer and Monetization, explained the move in a blog post. He said hardware supply constraints are changing device memory availability. Over time, this can harm the user experience. Android is therefore introducing broader memory limits. These limits aim to stop one app from using too much memory and slowing down the whole system.

    Google Play will set performance thresholds in three areas. These include dynamic memory usage, bitmap memory usage and code optimisation. Apps on Play will also need at least 25 percent coverage across optimisation, shrinking and obfuscation. Tools such as R8 can help meet this target. If an app exceeds the limits, the system may slow it down. In some cases, the system may also terminate it.

    Google has started adding new tools in Play Console to help developers prepare. These tools include deeper memory metrics in Android vitals. They also include a filter for out-of-memory crashes. In addition, developers can see DEX code optimisation insights for each uploaded app bundle. The console will also send alerts when apps cross the new thresholds. More tools, including deeper insights into the Android Memory Limiter, are expected later this year.

    Enforcement will begin in February 2027. Apps and games that miss the thresholds may lose visibility on Google Play. They may also face limits on publishing. Google says it will share more details later this year.

    A second requirement covers sign-in during device transfers. Google is introducing a Zero-Tap Sign-In standard. Apps that support user sign-in must restore the user’s signed-in state on a new Android device. They will need to use the Android Restore Credentials API. This rule will apply from April 2027. Apps that fail to meet it may lose full publishing access and Play Store visibility. Games are currently exempt. However, Google plans to issue separate guidance for gaming authentication in 2027.

    The timing is linked to hardware changes. Google first introduced memory limits with Android 17 on Pixel phones. Reports say the base versions of the Pixel 11 Pro and Pro XL ship with less RAM than last year’s models. As Android 17 spreads to more devices, memory configurations will vary widely. They may range from 4GB to 16GB and beyond. Therefore, Google is asking developers to prepare for a broader range of devices.

  • Bus Driver’s Quick Decision Saves Lives in Nepal Flood

    A bus driver’s quick decision may have saved two travellers from a flash flood near Nepal’s Kerung border. Anukul Poddar and his wife, Reba, were heading toward Tibet when the danger struck.

    The couple had travelled about one hour from the immigration centre. Around 9:30 am on Wednesday, the driver stopped the bus. He warned that a flash flood had hit the area. He then refused to continue on the same road. Shortly after the bus turned toward Kathmandu, floodwaters washed away the stretch where they had stopped.

    Anukul later described a cloud moving down the gorge and a hissing sound. At that moment, the group did not know the scale of damage at the Kerung immigration centre. The driver did not wait. He took another route and drove the passengers to Kathmandu. The journey from that point took about two hours.

    Minutes later, the travellers saw schoolchildren, local residents and vehicles rushing uphill. People were screaming as they ran. The scene showed how quickly the situation had changed.

    The Poddars later learned that another couple from their hometown had already reached the immigration centre. That couple has remained missing since the flood.

    Anukul and Reba, both 66, live in Basirhat in West Bengal. They were part of a pilgrim group called The Cholo Jai. The group left Kolkata on August 21 for the Kailash-Manasarovar journey. On Wednesday, they were scheduled to enter Tibet.

    Another couple from Basirhat, Swapan Mondal and his wife Mou, also retired schoolteachers, travelled with a different agency. They are known to the Poddars. Their group reached the immigration centre earlier. Swapan last sent a good morning message to Anukul at 8:30 am. The message included a photograph of the couple at the immigration office. There has been no contact since then.

    The two families usually travel together with the same agency. This year, a delay in Anukul’s passport renewal caused them to miss the original deadline. As a result, the Poddars joined the Cholo Jai team. The Mondals had to travel with another agency. Both groups still started on August 21 and boarded the same train.

    The Mondals’ team left Kathmandu on Tuesday and headed toward Kerung. They were supposed to stay overnight and reach the immigration office at 8:30 am. The Poddars’ team left Kathmandu early on Wednesday. Their scheduled arrival was around 10:30 am.

    State officials later said at least 39 people from West Bengal were reported missing. Family members and the administration then managed to contact the Poddar couple.

    On Saturday, the Poddars reached Raxaul in Bihar from Biratnagar in Nepal with other members of their team. They boarded the Mithila Express and were scheduled to reach Howrah early on Sunday.

    Officials had directed police to arrange flight tickets for the couple. However, the pair had already reached Biratnagar. Returning to Kathmandu for a flight would have taken more time. Therefore, they chose to travel by train.

    Their son, Satyaki Poddar, lives in New Town. He said the couple remains in shock. He added that they may stay with family for some days. There is still no news of the Mondal family. Relatives continue to hope for their safe return.

  • Tropical Storm Karina: A Potential Hurricane Threat to California

    Forecasters now expect Tropical Storm Karina to strengthen into a major hurricane. Some updated models also show paths that could bring effects toward California.

    The National Hurricane Center said Karina already has sustained winds above 50 mph. It may reach hurricane strength as early as Friday night.

    By Sunday morning, some forecasts show the storm becoming a Category 3 hurricane. That would mean winds above 111 mph.

    Spaghetti models display a range of possible tracks. A few of those tracks point toward the California coast. Earlier, the American GFS model showed scenarios that included a possible landfall near San Diego or Los Angeles. The European ensemble was more doubtful on Thursday and kept the storm offshore.

    Both model sets were updated on Friday. They now show a greater chance of paths toward Southern California and areas farther north.

    A hurricane making landfall in California remains highly unusual. The National Weather Service notes that the state has no recorded hurricane landfall in its history. The last tropical storm to affect the state directly was in 1997.

    Karina is currently less than 1,400 miles south of San Diego. It is moving northwest at about 13 mph, well off the Mexican coast.

    Even at that distance, the National Hurricane Center warned that tropical-storm-force winds extend more than 200 miles from the centre. Officials also expect swells along the southwestern coast of Mexico and the Baja California Peninsula this weekend. Those swells could create dangerous rip currents.

    Rip currents are strong, narrow flows that pull water away from the shore. They can quickly carry swimmers into deeper water and tire them as they try to fight the current.

  • Climate Change Drives Flash Floods in Nepal: A Scientific Perspective

    Scientists have linked yesterday’s flash floods in Nepal to climate change. Rushing water reportedly reached extreme heights after a glacier collapsed.

    Researchers are still examining the exact sequence of events. However, several experts point to global warming as a key factor.

    Dr Wouter Buytaert of Imperial College London described the disaster as typical of climate-driven events. Rising temperatures shrink glaciers and raise the chance they will break apart. At the same time, land degradation from wildfires, extreme weather, and unsustainable land use weakens valley slopes. In steep mountain valleys, these conditions create a high risk of sudden floods.

    The floods occurred only one month after a study warned of growing glacial collapse risk in the Himalayas. Researchers at Kathmandu University noted that the region is warming faster than the global average. This accelerates glacier melt and increases the danger of glacial lake outburst floods, or GLOFs.

    Officials in Nepal have called the damage severe. Floods destroyed buildings and bridges along the Nepal–Tibet border.

    The United States Geological Survey first reported the event as a magnitude 4.4 earthquake. Later analysis of seismic data and satellite images showed no earthquake occurred. Instead, a glacial collapse and debris flow caused the flooding.

    Dr Adrian McCallum, a glaciologist, said such events are becoming more common in alpine regions as the climate changes. Melting glaciers form lakes behind natural moraine dams. When those dams fail, large volumes of water rush down the valley and destroy everything in their path.

    Dr Ella Gilbert of the British Antarctic Survey added that climate heating is destabilising Himalayan glaciers. The rate of ice loss has doubled since 2000. When glacier stability declines, sudden failures can follow.

    A GLOF happens when water stored in a lake near or under a glacier is released suddenly. The flood can carry water, mud, rocks, and debris. It often damages settlements, roads, bridges, and farmland. Mountain regions such as the Himalayas face this hazard regularly.

    Nepal is especially vulnerable. Its steep terrain, fragile ecosystems, and limited adaptive capacity increase the risk. Climate-related disasters, including floods, landslides, glacier retreat, and GLOFs, have already caused significant loss.

    At least 45 GLOF events have occurred across 39 lakes in Nepal in recent decades. Several of them caused loss of life. Scientists warn that rising temperatures will make these events more frequent.

    Researchers note that Nepal already suffers climate-related losses at current warming levels. Further temperature rise would increase the risk of floods, glacier melt, GLOFs, and droughts.

    Experts hope the latest disaster will encourage better early-warning systems. Monitoring the build-up of water in glacial lakes could give downstream communities time to prepare. Such systems have the potential to save lives as similar events become more likely.

  • Kodagu District Faces Severe Flooding from Heavy Rain

    Heavy rain has lashed Kodagu district since Monday midnight. The district received steady rainfall throughout Tuesday.

    As a result, the water level in the Cauvery river rose sharply. The Bhagamandala Triveni Sangama went underwater for the second time. A coffee plantation at Kaggoddu near Madikeri also flooded.

    Kodagu recorded an average rainfall of 37 mm until Tuesday morning. Madikeri received 85.35 mm. Bhagamandala recorded the highest amount at 150 mm.

    The heavy rain increased inflow into the Harangi reservoir. The inflow reached 4,360 cusecs by Tuesday evening. Earlier, it stood at 3,638 cusecs at 8 am.

    The reservoir is already full. Authorities are therefore releasing 10,000 cusecs of water from the dam.

    In Aranthodu, the Koornadaka bridge went underwater after overnight rain. This bridge lies on the road that connects Peraje via Aletti-Baddadka.

    Consequently, vehicles and pedestrians must now take a longer alternative route.

  • Gurugram Faces Traffic Chaos as Heavy Rain Causes Waterlogging

    Heavy Rain Causes Waterlogging and Traffic Slowdown in Gurugram

    Heavy rain hit Gurugram on Monday. Several roads quickly filled with water. Traffic moved very slowly across the city. Commuters and vehicles faced difficulty on flooded stretches. The downpour disrupted movement during the working day.

    The showers formed part of a wider spell across Delhi-NCR. Water collected on many roads in Gurugram. Vehicles crawled through the worst-affected areas. Zones near Sikanderpur metro station also saw waterlogging. This added to the challenges for people travelling between Gurugram and Delhi.

    Social media users shared their experiences. One person noted that one hour of rain covered just one kilometre of progress. Others highlighted long traffic queues from Millennium City to Cyber City. Some pointed to the city’s ongoing drainage issues after heavy rainfall.

    This is not the first such event this month. Gurugram earlier faced extensive flooding and traffic delays during intense showers. Civic agencies then deployed pumps and dewatering equipment. Underpasses remain especially vulnerable. Heavy rain the previous day had already caused waterlogging and led to the temporary closure of the Medanta underpass.

    Monday’s rain also affected Delhi. Heavy showers led to waterlogging and traffic delays in multiple areas. The India Meteorological Department issued a red alert for heavy rain in several districts. A yellow alert covered moderate rainfall in others. Thunderstorms and strong winds were also expected in parts of the capital.

    Intense rain fell across South East Delhi, East Delhi, Shahdara, Central Delhi, and several other zones. South Delhi and nearby areas saw particularly heavy showers. Vehicular movement slowed across large parts of the national capital as a result.

  • Magnitude 5.9 Earthquake Shakes Eastern Japan

    A powerful tremor shook eastern Japan early Sunday. The shaking reached Tokyo and nearby areas. Residents woke suddenly and moved to safer spots. Officials reported 23 people injured across the region. Most injuries remained minor. Authorities also confirmed no risk of a tsunami.

    The Japan Meteorological Agency recorded the earthquake at a preliminary magnitude of 5.9. Its epicentre lay in southern Ibaraki prefecture at a depth of 70 kilometres. The US Geological Survey measured the same event at magnitude 5.8.

    Injuries occurred in four prefectures. Nine people suffered harm in Saitama. Another nine reported injuries in Kanagawa. Four people were hurt in Chiba. One person was injured in Ibaraki. Many fell or bumped into furniture and doors after the sudden shaking. They left their beds in haste when the tremor began.

    Train services faced disruption. Express trains between Tokyo and Narita Airport ran late. Other local services in northeastern areas also experienced delays. In contrast, Shinkansen bullet trains continued without interruption. East Japan Railway confirmed normal operations for the high-speed lines.

    The tremor triggered emergency alerts on mobile phones. Strong shaking was felt across Tokyo. Prime Minister Sanae Takaichi stated on X that the government had formed a task force. The team began assessing any possible damage.

    In addition, an underground water pipe broke in Tokyo’s Koto ward. Water spilled onto a road. Repair teams fixed the pipe quickly and stopped the leak. Traffic continued normally on roads in nearby cities such as Mito and Saitama.

    Authorities checked nuclear facilities as well. The Nuclear Regulation Authority found no abnormalities at about a dozen plants or related sites.

    This latest quake follows a strong magnitude 7.1 event that struck the Kumamoto area on Kyushu last month. That earlier tremor left hundreds of people injured.

  • Protecting Vulnerable Communities from Rising Heatwaves in India

    Heatwaves now form a regular part of summer across the Indian subcontinent. They disrupt daily life for millions of people. These events also place heavy pressure on systems designed to protect communities. Even small rises in temperature create large real-world effects.

    People lose wages and face more hospital visits. Productivity drops while electricity bills rise. The hardest impacts fall on the most vulnerable groups. Therefore, solutions must target those who need support the most.

    Heatwaves stand out among extreme weather events. They strongly affect people’s ability to work and earn. The Lancet Countdown estimated that heat cost India around 247 billion potential labour hours in 2024. This loss equalled about 194 billion dollars in income. A recent study from the University of California further suggested that one day of extreme heat can cause as many as 3,400 additional deaths across India.

    Temperatures near 50 degrees Celsius appear more often across South Asian plains. Researchers need clearer understanding of how extreme heat affects people. They also need practical safeguards against these risks.

    Outdoor workers and manual labourers face high exposure. So do people who care for children or elderly family members. Residents of crowded urban areas and those without adequate healthcare remain especially vulnerable. One UNEP estimate found that around 82 percent of India’s informal workforce lacks proper protection.

    Construction workers often illustrate these challenges. Many must complete fixed hours and bring their families to work sites. Children then face risks of dehydration, heat stroke and injury. Workers themselves also suffer. Some avoid bringing cooked food because heat spoils it quickly. Illness or childcare needs can then remove income from the household.

    People running households face harder daily choices. They decide whether to send children to school during extreme heat. They spend long hours in water queues. Even simple cooking decisions add stress. When millions face similar problems at once, health systems, urban infrastructure and the economy all feel the pressure.

    Communities need solutions that protect individuals while strengthening larger systems. Protecting livelihoods forms a clear priority. Parametric insurance offers one useful tool. It pays out based on a specific trigger rather than assessed damage. This approach delivers fast and predictable relief.

    Health systems can improve readiness before peak temperatures arrive. Early warning systems work best when linked to local health responses. Primary health centres should identify and treat heat exhaustion, dehydration and heat stroke. Frontline workers need proper training. Rising heat also expands the range of diseases such as dengue and malaria. Therefore, heat preparedness should connect with broader disease surveillance.

    SEWA’s parametric insurance programme serves as a practical example. It supports informal women workers in India. Women pay 250 rupees each year. When temperatures stay above 40 degrees Celsius for two days, they receive automatic cash assistance. This money helps cover income loss, buy essentials or avoid emergency debt.

    The South Asia Climate-Health Desk provides another useful model. The WHO-WMO Climate and Health Joint Programme launched this initiative. Partners including IITM and IMD help develop decision-support tools. The programme turns climate and weather data into timely health action. Vulnerable communities and health authorities can then respond before and during dangerous heat events.

    Every solution must match how people actually live through heat. Many receive heat alerts on their phones. Yet staying home is rarely possible. Preparedness must therefore support those most exposed and least protected. Workers need ways to earn without risking their health. Children and older people need safety. Cities must keep functioning without shifting the full cost of heat onto those least able to bear it. Building these safeguards remains an urgent priority.

  • Early End to India’s Monsoon: What to Expect This September

    India’s southwest monsoon may end earlier than usual this year. Extended-range weather models show a sharp drop in rainfall after the first week or two of September.

    The next four weeks look disappointing for most rain-dependent areas. East and Northeast India may still receive rain during the coming two weeks. Meanwhile, the rest of the country could see weaker monsoon activity as September continues.

    Models point to a significant rainfall reduction after 5 to 10 September. The weakening is likely to last through the second half of the month. As a result, the monsoon could start withdrawing from extreme northwest India between 10 and 20 September.

    This change would mark a clear shift. Active monsoon conditions would give way to a much drier pattern.

    For now, the main rain-bearing systems remain over East and Northeast India. Those regions may continue to get moisture and showers. Elsewhere, rainfall is expected to turn patchy.

    September normally supplies important late-season rain. Many areas rely on it to make up for earlier shortages. A long dry spell during the month could therefore lower the overall seasonal rainfall total.

    The southwest monsoon usually begins its retreat from northwest India first. It then moves across the rest of the country. Withdrawal requires more than a few dry days. It needs a lasting drop in rain-bearing conditions and a change in the larger monsoon circulation.

    Current model outlooks suggest this transition may start over extreme northwest India in mid-September.

    However, weather models keep updating. A new low-pressure system or a shift in atmospheric patterns could still change the picture.

    For now the signal remains consistent. India may have only a couple of weeks of useful monsoon rain left before September becomes much drier and the annual withdrawal begins.
