Low pressure to bring very heavy rain in south Bengal for two days
Kolkata, Jul 24 (PTI) A low-pressure area over the Bay of Bengal will bring heavy to very heavy rainfall, with isolated extremely heavy downpour, in the southern districts of West Bengal for the coming two days, the IMD said on Thursday.
A low-pressure system, which has formed over the north Bay of Bengal, will become well-marked by Friday and move west-northwestwards towards West Bengal and adjoining north Odisha coasts, the Indian Meteorological Department (IMD) said in its forecast.
It said that owing to the low-pressure area and strong monsoon flow, heavy to very rainfall is very likely to occur at one or two places over North and South 24 Parganas, Purba and Paschim Medinipur districts and heavy rainfall at one or two places in the other districts of south Bengal on Thursday.
The IMD said that heavy to very heavy rainfall will occur at a few places, with extremely heavy downpour at one or two places is very likely over Bankura and Paschim Medinipur districts, while heavy to very heavy downpour will occur at one or two places over Jhargram, Purba Medinipur, Purulia, Hooghly and South 24 Parganas districts on Friday.
The sub-Himalayan districts of Darjeeling, Kalimpong and Jalpaiguri are likely to receive heavy rainfall from Friday to Sunday, it said.
Advising fishermen not to venture into the sea over the north and central Bay of Bengal and along and off the coasts of West Bengal and Odisha, the IMD said squally weather with surface wind speed reaching up to 55 kmph is likely to prevail over these areas from July 24 to 28.
The weather office warned of heavy rainfall in Kolkata till Saturday morning owing to the low pressure over north Gangetic West Bengal. PTI AMR NN

Uttarakhand flash floods: State seeks Doppler radars, high-tech warning systems
Uttarakhand has urged the Union government to set up three Doppler radars in the state's higher reaches, like Kedarnath and Bhagirathi valleys, and help it with high-tech early warning systems for flash floods and landslides to deal with extreme weather events. Climate change and environmental degradation have triggered a string of disasters in Uttarakhand. (PTI) The request was made days after flash floods in Uttarkashi. Climate change and environmental degradation have triggered a string of disasters in Uttarakhand over the last few years. 'We requested NDMA [the National Disaster Management Authority] to set up three Doppler radars in the higher reaches of Uttarakhand,' said secretary (home) Shailesh Bagauli on Friday. 'We have three Doppler radars. But three in higher reaches will help us in dealing with extreme weather there.' The Doppler radars provide advanced information, enhancing the lead time essential for saving lives and property in the event of a disaster associated with severe weather. Conventional radars can track and predict cyclones. Doppler radars provide detailed information on the internal wind flow and structure. The severity of the weather systems can thus be quantitatively estimated more accurately, and more precise warnings can be generated to save lives and property. Uttarakhand has Doppler radars at Lansdowne (Pauri Garhwal), Mukteshwar (Nainital), and Surkanda (Tehri Garhwal). They were set up a year after the 2013 flash floods in Kedarnath, which killed 4,127 people, under a programme to improve weather forecast services in the Himalayan states and help in reducing human losses due to extreme weather events. Activist Ajay Gautam, who has filed petitions related to disasters in the state, said higher Himalayan valleys are more susceptible to tragedies like the one in Kedarnath in 2013, and in Chamoli in 2021, when a glacial burst claimed 204 lives. He said such incidents will continue, and the government has to prepare and take measures to lessen human losses. 'One of the best ways to do this is to establish advanced warning systems and more Doppler radars, for which I had filed a plea in the Uttarakhand high court in the aftermath of the 2013 tragedy. Three have been set up, but we need more in higher reaches. The severity of the weather systems, many of which trigger landslides and cloud bursts, can help authorities to quantitatively estimate the weather more accurately and issue more precise warnings for saving human lives.' Over 51% of the state is in very high landslide susceptible zones, according to Dehradun's Wadia Institute of Himalayan Geology.

Flash floods kill at least 10 people, leave 33 missing in northwestern China
Beijing, Aug 8 (AP) At least 10 people have died and 33 are missing after flash foods in Yuzhong County in China's northwestern Gansu province, Chinese state media reported. Heavy rains since Thursday have triggered flash floods and at least one landslide in mountainous areas near the city of Lanzhou, according to state broadcaster CCTV. The downpour knocked out power and telecommunications services in the Xinglong mountain area, leaving more than 4,000 people across four villages stranded. Chinese President Xi Jinping urged all-out rescue and flood prevention efforts in the area. (AP) GSP First Published: Disclaimer: Comments reflect users' views, not News18's.

How ISRO's Satellite Insights Are Helping Uttarkashi Disaster Relief Ops
Satellite images, extracted by the Indian Space Research Organisation (ISRO), have revealed the scale of destruction caused by the deadly flash floods in Uttarakhand's Uttarkashi earlier this week. The disaster, on August 5, killed five people and left over 50 people missing. Experts suspect the burst of a glacial pond triggered the deluge. Two days after the floods, ISRO's Cartosat-2S satellite captured high-resolution images of the affected zone. The pictures, taken on August 7, show a large, fan-shaped deposit of mud and debris, covering nearly 20 hectares (approximately 750 metres by 450 metres), at Dharali village, where the Kheer Gad stream meets the Bhagirathi River. ISRO says this mapping is guiding search and rescue teams to priority locations, identifying submerged areas, and helping officials restore connectivity to cut-off villages. The National Remote Sensing Centre (NRSC) in Hyderabad conducted a rapid assessment, comparing the post-disaster images with cloud-free pre-event data from June 13, 2024. Satellite Insights Aiding Rescue & Relief Ops ISRO/NRSC used Cartosat-2S data to assess the devastating Aug 5 flash flood in Dharali & Harsil, Uttarakhand. High-res imagery reveals submerged buildings, debris spread (~20ha), & altered river paths, vital for rescue teams on… — ISRO (@isro) August 7, 2025 The analysis shows widened stream channels, altered river morphology, and severe destruction of infrastructure. Several houses in the flood-affected zone have disappeared, likely swept away or submerged under mud and debris. Roads, bridges, plantations, and homes were either destroyed or heavily damaged. The before-and-after images show the aftermath. Dharali and the Bhagirathi River appear intact in June 2024, with houses lining the riverbank. The August 2025 images show thick mud and sediment deposits across the floodplain, with many structures gone. "A number of buildings appear to be submerged with mud-debris in Dharali village. The satellite images will assist ongoing search and rescue efforts to reach stranded individuals and restore connectivity to the isolated region," ISRO said in its official statement. The space agency also said the image showed the increasing vulnerability of Himalayan settlements to natural disasters. ISRO Findings: Widened stream channels and altered river flow due to the flash floods. Fan-shaped deposit of sediment and debris at Dharali (about 20 hectares in size). Partial or complete destruction of several buildings in the affected area. Extensive mud and sediment deposition covering riverbanks and houses. The NRSC said the rapid mapping was conducted in a short timeframe and quality-checked under ISRO procedures. Geographic details are subject to limitations due to image resolution and interpretation. Search and rescue operations are underway in the affected villages, with efforts focused on locating the missing and restoring essential connectivity.
