Depression in Bay of Bengal Triggers Severe Weather Warning: Heavy Rain and Gusty Winds Across 23 States A depression over the Andaman Sea and the Bay of Bengal has prompted warnings of 70 km/h squalls in the archipelago, while active weather systems bring widespread rainfall and sharp temperature drops to 23 Indian states. A newly formed atmospheric depression over the seas has intensified wet conditions across India, triggering widespread warnings for heavy precipitation, thunderstorms, and intense wind activity spanning 23 states. The marine system concentrated over the Andaman Sea and the adjoining south-east Bay of Bengal threatens to batter the archipelago with torrential downpours and perilous maritime disturbances. Concurrently, extensive moisture movement across northern, eastern, central, and peninsular regions has produced an unseasonal cooling effect and substantial atmospheric instability. Andaman and Nicobar Islands Brace for Squally Conditions and Rough Seas Owing to the active depression, the Andaman and Nicobar Islands face forecasts of widespread to very widespread precipitation accompanied by lightning on September 29. Intermittent showers and thunderstorm activity are projected to persist across scattered locations between September 30 and October 4. Atmospheric dynamics on September 29 could generate squall conditions over the islands, with sustained winds blowing at 50 to 60 km/h and peak gusts accelerating up to 70 km/h. Sea conditions are anticipated to remain rough to very rough with towering swells through the evening of September 29 across the Andaman Sea, the adjacent south-east Bay of Bengal, and adjacent waters near the Myanmar coastline, prompting stringent warnings against venturing into the waters. Delhi-NCR Shatters 25-Year Minimum Temperature Mark Amid Steady Showers The National Capital Region has experienced a stark meteorological shift driven by continuous overcast skies, light showers, and cool breezes. This persistent pattern has driven mercury levels downward across the urban belt. In the Ridge area of Delhi, the minimum temperature plummeted below 17 degrees Celsius, establishing the lowest reading observed in the past 25 years. Atmospheric instability is slated to sustain periodic rain and thunderstorm episodes over scattered localities in Delhi and adjacent satellite towns on September 29, 2026. Uttar Pradesh Grapples with Devastating Floods and High Fatality Toll Consecutive days of torrential precipitation over the past forty-eight to seventy-two hours have triggered catastrophic flooding across several districts in Uttar Pradesh. Waterlogging and surging waterways have caused severe disruption, and weather-related incidents have tragically claimed more than 80 lives statewide. Eastern sectors of the state remain under precipitation warnings through September 30, with sporadic rain and overcast conditions expected to prevail over other portions of the state as well. Persistent Wet Spell Grips Eastern Belt: Bengal, Bihar, Jharkhand, and Odisha The eastern states have endured non-stop moisture influx for over a week, leading to repeated rain cycles across Bihar, Jharkhand, Gangetic West Bengal, and Odisha. In Bihar, rainfall probabilities remain active through October 1. Isolated to fairly widespread showers accompanied by thunder and lightning are forecast to affect Gangetic West Bengal, Odisha, Jharkhand, as well as Sub-Himalayan West Bengal and Sikkim, through October 4. Hill Regions Face Landslide Risks and Gusty Conditions North-western montane territories are observing an elevation in weather-induced hazards. Himachal Pradesh has been placed on alert for heavy downpours accompanied by above-normal wind velocities, bringing severe threats of hillside landslips and debris flow. Authorities and commuters in the region have been cautioned to maintain heightened vigilance. In Uttarakhand, wet spells are slated to continue from September 29 through October 4, depressing daytime maximums and night-time minimums well below regional averages. Over Jammu, Kashmir, and Ladakh, multiple sectors are expecting thunderous showers coupled with unusually brisk winds. Plains of Punjab, Haryana, and Rajasthan Experience Weather Shifts The plains of north-west India continue to register broad impacts from the prevailing circulation. Punjab has experienced a notable temperature dip following two to three days of light to moderate precipitation, keeping atmospheric conditions pleasant, with scattered showers predicted on September 29. Haryana is likely to see further lightning and scattered precipitation alongside brisk breezes that keep day and night readings lower than seasonal baselines. In Western Rajasthan, localized rain is expected on September 29, after which largely dry conditions should establish control over most districts from September 30 onward. Central Belts: Trajectory Across Madhya Pradesh and Chhattisgarh Central Indian geography shows a staggered distribution of rainy spells. Western Madhya Pradesh is slated for precipitation on September 29, whereas eastern districts could witness thunder and showers extending until October 2. Weather systems over Vidarbha are projected to bring rain through September 30, while Chhattisgarh remains susceptible to isolated showers and thunderstorm activity until October 4. Northeastern Frontiers Expect Heavy Downpours Through October 4 All seven northeastern states are witnessing heightened monsoon activity fueled by strong humidity surges. Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura will observe scattered to widespread rain through October 4. Specifically, intense and heavy rainfall alerts have been issued for Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura on September 29 and 30. Arunachal Pradesh is projected to receive localized heavy falls later in the cycle, spanning October 3 and 4. Western Coast: Gusty Winds and Showers in Maharashtra and Gujarat Parts of western India will navigate both rainfall and high-velocity wind gusts. On September 29, Madhya Maharashtra faces squally conditions with winds traveling at 40 to 50 km/h and peak gusts hitting 60 km/h. Coastal belts of Konkan and Goa are expected to experience breezes blowing at 30 to 40 km/h with gusts touching 50 km/h. Showers are forecast to persist over Konkan, Goa, and Madhya Maharashtra until October 4. Marathwada is on rain watch for September 29, whereas Gujarat region remains wet through October 1, and the Saurashtra-Kutch pocket receives showers between September 30 and October 1. Peninsular South: Intense Wet Spells for Karnataka, Kerala, and Tamil Nadu The southern peninsula faces an extended period of precipitation and squally weather across multiple corridors. Coastal Andhra Pradesh, Yanam, Lakshadweep, Rayalaseema, North Interior Karnataka, Tamil Nadu, Puducherry, and Karaikal will experience localized showers from September 29 to October 4. South Interior Karnataka is slated for widespread rainfall from September 29 to October 1, with heavy precipitation persisting through October 2. Coastal Karnataka is set for widespread rain on October 1 and 2. Tamil Nadu, Puducherry, and Karaikal face heavy downpours through October 1, while Kerala and Mahe anticipate heavy rain from September 30 to October 3, culminating in very widespread and intense wet spells between October 1 and 4. What this means for you The synchronized activation of severe weather across 23 states directly influences daily transport, agricultural security, and public health. • Transport and Commuter Disruptions: Sustained winds and squalls of up to 70 km/h across the Andaman Sea and coastal belts threaten to delay maritime and aviation services. Passengers traveling through or toward coastal airports must confirm schedules in advance. • Severe Threat to Standing Crops: Persistent waterlogging across Uttar Pradesh, Bihar, and Madhya Pradesh risks lodging and submergence damage to near-harvest crops. Farmers must immediately clear field drainage channels to prevent substantial yield write-offs. • Landslide Hazards Along Mountain Corridors: Downpours over Himachal Pradesh and Uttarakhand significantly raise the danger of slope instability and road closures. Commuters and tourists are urged to avoid treacherous ghat segments and heed local administration advisories. • Sharp Drop in Ambient Temperatures: Unseasonal temperature plummets below 17 degrees Celsius in Delhi-NCR signal an early cold transition. Residents should prepare for seasonal respiratory sensitivities and sudden temperature swings. Why this happened A deep marine depression coupled with multiple interacting low-level moisture channels across the subcontinent has driven this widespread rainfall episode. • Formation of Bay of Bengal Depression: The concentration of a tropical depression over the Andaman Sea and adjacent southeastern waters rapidly channeled intense moisture, creating squally winds and stormy seas. • Concurrent Regional Circulation Systems: Multiple regional troughs and cyclonic circulations became active simultaneously across the plains, the northeastern states, and peninsular India. • Unprecedented Moisture Trapping Over Plains: Relentless rainbands and cool easterly currents trapped over northern India suppressed diurnal heating, precipitating a 25-year minimum temperature record in Delhi.
