Cyclone Murasu Stalls Early Winter in Bengal, Mercury to Dip Post November 5 Moisture pulled by the cyclone over coastal Andhra Pradesh has raised nighttime temperatures across West Bengal, but skies clearing from Wednesday will pave the way for cooler days ahead of Kali Puja. A cyclonic disturbance spinning over the Bay of Bengal has interrupted the customary transition into autumn chill across eastern India. Instead of crisp morning breezes, residents across West Bengal are experiencing sticky humidity and above-average temperatures as the indirect cloud canopy from Cyclone Murasu continues to linger over the region. The cyclonic storm, which made landfall along the Andhra Pradesh coast, has held back the winter chill that typically begins to settle across the plains during the first week of November. Severe Downpours Across Coastal Corridors While the core circulation made its strike in coastal Andhra Pradesh, the system has triggered widespread atmospheric turbulence across the eastern seaboard. Coastal swathes of Andhra Pradesh, Odisha, and Tamil Nadu remain braced for intense precipitation, with meteorological authorities issuing red alerts for vulnerable sectors facing extreme downpours. Even though West Bengal remains shielded from a direct strike, the storm's extensive peripheral feeder bands are dragging substantial oceanic moisture inland. This atmospheric blanket kept the skies partially overcast across every district on Tuesday, accompanied by intermittent light spells. District-Wise Rainfall Dynamics The system's indirect footprint reflects contrasting patterns across the northern and southern halves of the state. In North Bengal, isolated light drizzle remains confined to select sub-Himalayan pockets, specifically Darjeeling, Kalimpong, Jalpaiguri, Alipurduar, and Cooch Behar. The remaining three northern districts are slated to stay largely dry throughout this transitional spell. Conditions across South Bengal have been more dynamic, with convective cloud formation sparking scattered thundershowers. Localized showers paired with lightning were forecast across North 24 Parganas, South 24 Parganas, Kolkata, Howrah, Hooghly, Purba Medinipur, Paschim Medinipur, Jhargram, Bankura, and Purulia. Other southern pockets are projected to see primarily dry spells. Starting Wednesday, November 5, and lasting through Saturday, rain activity will dissipate statewide, establishing a sustained stretch of predominantly dry conditions as cloud decks thin out. Elevated Heat and Humidity in Kolkata The influx of coastal moisture has severely compromised comfort levels in Kolkata. On Monday, the city logged a peak daytime temperature of 31.04 degrees Celsius, edging slightly beyond the seasonal baseline of 31 degrees Celsius. More significantly, the overnight minimum settled at 25.02 degrees Celsius, registering 2.03 degrees above what is normal for early November. Relative humidity levels oscillated sharply between 67 and 95 percent throughout the day. This trapped moisture layer has arrested radiation cooling, forcing residents to endure oppressive mugginess rather than welcome autumn breezes. Clearing Skies to Usher in Pre-Kali Puja Chill Atmospheric models indicate that the trapped warmth will break once the remnants of the cyclonic system dissolve entirely. Beginning November 5, dissipating cloud cover will allow nocturnal terrestrial radiation to escape freely, setting off a progressive decline in night readings. Meteorologists anticipate that this gradual cooldown will introduce a noticeable nip in the air right before the Kali Puja festivities slated for November 8. The pace and intensity of this impending drop will ultimately hinge on how rapidly dry continental winds replace the prevailing maritime air mass. What this means for you Persistent cyclonic moisture is causing uncomfortable humidity across West Bengal, but a marked shift toward cooler and drier weather will begin after midweek. • In West Bengal: Scattered showers and heavy humidity will cause muggy conditions across most districts through Tuesday. Skies will clear from November 5 onwards, pulling nighttime temperatures down just in time for comfortable outdoor festivities during Kali Puja on November 8. • In coastal Andhra Pradesh and Odisha: Extreme rain alerts and strong coastal winds pose localized flooding and travel hazards. Fishermen and coastal communities must adhere to red alerts and avoid venturing near the turbulent surf. • For daily households: High relative humidity touching up to 95 percent in Kolkata means air conditioning or fans remain necessary despite early November dates. Once nighttime temperatures drop after Wednesday, households can expect the gradual arrival of pleasant winter conditions. • For festive shoppers: Brief thundershowers in ten southern districts on Tuesday could disrupt street commerce temporarily. Clear and predominantly dry conditions from Wednesday through Saturday will offer ideal weather for open-air market visits. Why this happened The sudden stall in autumn cooling stems from the peripheral reach of Cyclone Murasu, which pumped vast plumes of maritime moisture across the eastern seaboard after hitting the Andhra Pradesh coast. • Peripheral cloud cover: Although the storm center made landfall along coastal Andhra Pradesh, its extensive outer moisture bands pushed directly across West Bengal. This thick cloud envelope acted as an insulating layer, trapping surface heat and causing minimum readings to hover above normal. • High moisture block: Relative humidity surged to 95 percent in Kolkata, creating severe mugginess. The steady influx of humid sea breezes effectively blocked the entry of dry, cool continental northerly winds that usually usher in early winter. • Upcoming synoptic change: As the cyclonic system gradually dissolves, the moisture supply will cut off from Wednesday onward. Cloud-free skies from November 5 will allow unhindered radiative cooling at night, steadily driving down the mercury toward seasonal norms. Questions & Answers 1. Why has the arrival of winter been delayed in West Bengal? The indirect influence of Cyclone Murasu over the Andhra Pradesh coast has trapped thick cloud cover and high humidity over Bengal, keeping temperatures above normal. 2. When is the weather expected to clear and temperatures to drop in Bengal? Meteorological authorities anticipate conditions will turn predominantly dry from November 5, initiating a gradual decline in night temperatures. 3. What will the weather feel like around Kali Puja in West Bengal? With clouds expected to dissipate after November 5, a perceptible autumn chill is projected to emerge across the state ahead of Kali Puja on November 8. 4. Which states have received red alerts due to Cyclone Murasu? Heavy downpours have been forecast for coastal belts of Andhra Pradesh, Odisha, and Tamil Nadu, where select sectors have been placed under red alerts. 5. What were the temperature and humidity readings recorded in Kolkata on Monday? Kolkata recorded a high of 31.04 degrees Celsius and a low of 25.02 degrees Celsius (2.03 degrees above normal), with relative humidity ranging between 67 and 95 percent. 6. Which South Bengal districts face rain and thundershowers on Tuesday? Scattered thundershowers were forecast for Kolkata, Howrah, Hooghly, North and South 24 Parganas, Purba and Paschim Medinipur, Jhargram, Bankura, and Purulia. https://trendkia.com/en/national/west-bengal-men-chakravata-murasu-ne-barhai-umasa-pancha-navnbara-se-para-lurhakane-ke-asara-55623 TrendKia — Har trend, sabse pehle.
