Even as the monsoon season begins to weaken, atmospheric instability is driving a fresh spell of severe weather across large parts of the country. A series of active weather systems has triggered rain and storm warnings across 14 states, including Uttar Pradesh, Bihar, Delhi, Jharkhand, Rajasthan, Madhya Pradesh, and Punjab. In several vulnerable pockets, wind speeds could escalate up to 70 kilometers per hour, while eastern India faces an elevated threat of lightning strikes and thunderstorms.
Travelers planning road or train journeys over the weekend have been urged to monitor regional forecasts closely. In mountainous terrains, heavy downpours carry a heightened risk of landslides, while plains could witness disruptions from sudden gale-force winds and waterlogging.
Multiple Cyclonic Circulations Fueling Widespread Instability
The sudden intensification of weather activity stems from multiple synchronized circulations over maritime and inland regions. A weather system developing over the Bay of Bengal is projecting its influence across central and eastern India. Simultaneously, an upper air cyclonic circulation persists over the southeast Arabian Sea near the Kerala coastline, mirrored by another active system hovering above the southwest Bay of Bengal.
Atmospheric circulations are also active over Sikkim and its neighboring regions. Detail from the India Meteorological Department's update on X shows that an upper air cyclonic circulation is positioned over northeast Assam and adjacent tracts, featuring a north-south trough in the lower tropospheric levels aligned near 92.5 degrees East and 24.8 degrees North, accompanied by an upper air cyclonic circulation over the west-central Arabian Sea. These interacting mechanisms are sparking severe convective activity, raising the likelihood of thunderstorms and hail in localized areas. The unstable conditions pose operational challenges for farmers with standing crops, while fishermen have been advised to stay clear of open sea areas and remain in safe harbors.
Delhi and Surrounding Areas Brace for Changing Conditions
The national capital region is slated for a noticeable weather shift on October 4. Forecasters anticipate localized showers accompanied by squally winds across Delhi-NCR. Daytime mercury levels in the capital are likely to settle near 35 degrees Celsius, while nighttime minimum temperatures could drop to around 24 degrees Celsius.
While the precipitation will bring welcome relief from recent sultry conditions, the combination of gusty winds and rain is likely to hinder traffic movement along major transit corridors. Commuters navigating open stretches and arterial highways have been advised to take precautions, as peripheral NCR sectors are also expected to experience fluctuating weather patterns.
Uttar Pradesh Faces Heavy Rain and Gusty Winds Across Multiple Districts
Extensive weather disturbances are projected across a vast swathe of Uttar Pradesh on October 4. Moderate to heavy rainfall warnings have been put in place for Meerut, Ghaziabad, Gorakhpur, Agra, Mathura, Kanpur, Siddharthnagar, Shravasti, Sitapur, Balrampur, Sant Kabir Nagar, Mau, Prayagraj, Maharajganj, and Kushinagar.
Wind gusts across these districts are anticipated to clock between 30 and 40 kilometers per hour. Such sudden bursts of wind alongside sustained rain threaten to flatten mature crops in agricultural belts, requiring growers to take protective measures. In the state capital Lucknow, the maximum temperature is expected to reach 34 degrees Celsius, with the minimum settling at 24 degrees Celsius.
Severe Downpours and Lightning Hazards Across Bihar
Bihar is set to witness widespread stormy conditions affecting northern, central, and southern territories alike. Regions placed on alert include East Champaran, West Champaran, Siwan, Saran, Gopalganj, Vaishali, Samastipur, Darbhanga, Madhubani, Araria, Katihar, Purnia, Kishanganj, Supaul, Saharsa, Begusarai, Bhagalpur, Gaya, and Patna.
Meteorological projections warn of squalls reaching speeds of 30 to 40 kilometers per hour, accompanied by frequent lightning discharges and concentrated downpours. Residents have been strongly cautioned against taking shelter under isolated trees or near electrical infrastructure during convective storms. In Patna, daytime temperatures are projected at 33 degrees Celsius, dropping to 24 degrees Celsius overnight.
Jharkhand Forecasts Strong 50 Kmph Winds Alongside Showers
Weather systems across Jharkhand are projected to remain vigorous through October 4 and October 5. Alerts for moderate rainfall and associated convective storms have been issued for Ranchi, Jamshedpur, Chatra, Deoghar, Bokaro, Gumla, Hazaribagh, East Singhbhum, West Singhbhum, Godda, and Palamu.
Wind speeds in specific districts could peak between 40 and 50 kilometers per hour during squall lines. These atmospheric conditions carry a serious danger of lightning strikes in rural and open landscapes. In Ranchi, the daytime high is forecast at 29 degrees Celsius, with nighttime readings dipping to a cooler 20 degrees Celsius.
West Bengal on Guard Against Stormy Winds and Rain
The impact of active circulations will be strongly felt across West Bengal. Heavy rain and gusty winds are projected to sweep across Darjeeling, Kalimpong, Jalpaiguri, Alipurduar, and Cooch Behar in the north, alongside Bankura, Birbhum, Purba Bardhaman, Paschim Medinipur, Durgapur, and Kolkata.
Wind gusts ranging from 40 to 50 kilometers per hour are expected across several zones. In hilly sectors like Darjeeling and Kalimpong, continuous rainfall raises the risk of landslides and traffic blockages on crucial mountain routes. In Kolkata, the maximum temperature is expected to hover around 34 degrees Celsius with a minimum of 26 degrees Celsius, with potential drainage challenges in low-lying urban pockets.
