India's monsoon crisis has intensified after two cloudbursts struck Jammu and Kashmir within hours, triggering flash floods and damaging homes, shops, schools, and commercial establishments.

The first cloudburst hit the Chhatru area of Kishtwar district, while another struck Pahalipora village in Doda district, sending torrents of water and mud through residential areas. Emergency teams, including the State Disaster Response Force (SDRF), police, and district authorities, launched rescue operations and safely evacuated residents. Authorities have reported no casualties so far, while damage assessments continue.

The latest incidents come as devastating floods continue across several Indian states. Assam remains the worst-affected state, with at least 82 flood-related deaths, while Odisha, Gujarat, Uttarakhand, Chhattisgarh, and Himachal Pradesh are also grappling with heavy rainfall and widespread flooding.

The last time the capital witnessed a colder January night was on January 11, 2023, when the mercury fell to 1.4 degrees Celsius. Across weather stations, daytime temperatures largely stayed below average. Safdarjung Observatory, the city’s primary weather station, reported a maximum of 18.8 degrees Celsius.

Delhi Pollution: IndiGo, Air India War of Delays, Cancellations as Toxic Fog Blankets Delhi-NCR

Delhi Pollution: IMD Warns Cold-Wave Like Conditions, Issues Yellow Alert

Amid the ongoing Northeast monsoon, two weather systems are brewing in the Bay of Bengal, off India's southeast coast. One of them is a well-marked low-pressure area adjoining the Andaman Sea, and this system is likely to move west-northwestwards and concentrate into a depression over the South Andaman Sea by Tuesday, (25th Nov). In addition to this, a low-pressure area is likely to form between the Indian mainland's southernmost tip and Sri Lanka, around Tuesday, and intensify thereafter, warned the Indian Meteorological Department(IMD).&nbsp;In meteorology, a low-pressure area is one where the atmospheric pressure is lower than the surrounding areas. It is associated with cloud formation, increased, humidity and rainfall. It causes moderate rain, cloudy skies. If multiple factors are favourable, a low-pressure area could gradually intensify in a phased manner into a depression and later into a cyclonic storm.&nbsp;Rainfall data shared on Monday (23rd Nov), showed that two locations in Tirunelveli district in Southern Tamil Nadu recorded over 22 cms of rainfall over the last 24 hours. Over 20 cm of rainfall in 24 hours is categorised as extremely heavy rainfall. Dozens of locations along coastal Tamil Nadu recorded over 11 cm of rainfall over the same period.&nbsp;Owing to the two weather systems that are evolving in the Bay of Bengal, an alert for heavy rain has been issued for multiple districts across coastal Tamil Nadu through this week. Heavy to very heavy rainfall has been forecast for Chennai and adjoining districts on Saturday, (29th Nov), followed by heavy rain on Sunday.&nbsp;Owing to rough sea conditions and gusty winds, fishermen have been warned against venturing out to sea along the Tamil Nadu coast through this week. Wind speeds are expected to touch 65kmph along parts of the Tamil Nadu coast, warned the IMD.

Two weather systems brewing in Bay of Bengal; Cyclone likely, says IMD

Tamil Nadu is likely to experience very heavy to extremely heavy rain, as the Bay of Bengal is set to witness a low-pressure area intensify into a depression on Wednesday. This weather condition will trigger widespread downpours across the coastal and northern districts of the state.&nbsp;Meanwhile, the India Meteorological Department (IMD) has issued a red alert for Mayiladuthurai, Chengalpattu, Villupuram, and Cuddalore districts. It also forecasted intense showers through the next few days.&nbsp;In addition, the impact of incessant rain has already begun; however, there have still been no reports of extremely heavy rainfall. After the continuous rain, water has entered homes in low-lying areas of the Tuticorin and Tiruvarur districts, prompting citizens to wade through knee-deep water.&nbsp;A large part of the paddy fields also remain submerged in the Tiruvarur and Nagapattinam districts, sparking anxiety among farmers. "The submerged paddy will sprout if the rain doesn't stop. It will be a major loss for us," a farmer in Nagapattinam told NDTV.<h3>Educational institutions remained closed</h3>Cuddalore received the heaviest rainfall at 174 mm, followed by Puducherry with 147 mm and the Nungambakkam area of Chennai with 86.4 mm over 21 hours ending at 5:30 am on Tuesday. Educational institutions remained shut in 13 districts and in Puducherry, while in Chennai, Salem, Namakkal, and Pudukkottai, only schools were closed.&nbsp;Chief Minister MK Stalin has designated 12 IAS officers as monitoring officers for districts under red alert and instructed authorities to prepare relief camps, evacuate residents from vulnerable areas, and carry out immediate relief operations. Stalin also instructed officials to speed up paddy procurement and ensure safe storage in the delta districts.&nbsp;Meanwhile, Deputy Chief Minister Udhayanidhi Stalin reviewed preparedness on the ground and district collectors assured readiness for the residents. Chengalpattu Collector D Sneha told NDTV, "We've completed pre-monsoon desilting work. Water pumps, relief centres, and community kitchens are ready. We would also hold special medical camps soon after the rain."&nbsp;The IMD data indicated that heavy to very heavy rain is likely to continue over the next three days, and extremely heavy rainfall could also hit the isolated places in Cuddalore, Chengalpattu, Villupuram, Mayiladuthurai, and Puducherry.&nbsp;Several other districts, which include Chennai, Thanjavur, Kancheepuram, Tiruvarur, Tiruvallur, and Nagapattinam, are also likely to witness intense spells of rain till Friday.
