Extended Severe Weather Pattern Grips Multiple Indian Regions
The India Meteorological Department has issued a significant weather alert predicting an extended period of intense weather activity that will affect substantial portions of southern, eastern, and northeastern India throughout the coming week. According to the All India Weather Summary and Forecast Bulletin released on November 24, the period from November 25 to November 30 will witness multiple weather disturbances including heavy to very heavy rainfall, thunderstorms accompanied by strong winds, rough sea conditions, and fog in specific northern and northeastern areas.
Tamil Nadu Braces for Most Intense Rainfall Phase
Tamil Nadu is expected to experience the most prolonged and severe rainfall episode during this weather event. The forecast indicates heavy rainfall from November 25 to 27, escalating to very heavy rainfall from November 28 to 30. Both interior and coastal regions, including Puducherry and Karaikal, will be significantly affected by what meteorologists describe as one of the season's strongest rainfall events, connected to developing systems over the Bay of Bengal.
Kerala and Mahe regions will receive heavy rainfall on November 25 and 26, with precipitation intensity expected to diminish afterward. The IMD attributes this widespread rainfall activity to moisture convergence and the influence of a cyclonic circulation developing over the Comorin region during the initial two days.
Andaman & Nicobar Islands Face Extended Rainy Spell
The Andaman & Nicobar Islands are preparing for nearly a full week of unsettled weather conditions. The archipelago will experience heavy rainfall on November 25, followed by heavy to very heavy rainfall from November 26 to 28. Another round of heavy precipitation is anticipated on November 29, making this one of the most prolonged rainy phases in recent months.
Coastal Andhra Pradesh and Yanam will encounter heavy rainfall toward the end of the forecast period, with significant precipitation expected on November 29, escalating to heavy to very heavy rainfall on November 30 as strong easterly winds intensify over the region.
Thunderstorms and Severe Sea Conditions Expected
Frequent thunderstorm activity accompanied by lightning is forecast across Tamil Nadu, Kerala, Mahe, and Coastal Andhra Pradesh on various days throughout the week. However, the Andaman & Nicobar Islands will experience the most severe thunderstorm-related weather, including gusty winds reaching 40-50 kmph between November 25 and 30.
Maritime conditions will deteriorate significantly from November 26 to 27 over the southeast Bay of Bengal and south Andaman Sea. Weather models predict squally winds of 45-55 kmph gusting up to 65 kmph, with some sectors experiencing gale-force winds reaching 60-80 kmph and gusting up to 90 kmph. These dangerous conditions are associated with a developing cyclonic system expected to intensify in the coming days.
Fishermen Warned Against Venturing into Sea
With rough sea conditions anticipated across multiple oceanic sectors, the IMD has issued stringent warnings for fishing communities. Fishermen have been strongly advised to avoid several maritime areas including:
- South Andaman Sea until November 27
- Southeast Bay of Bengal from November 25 to 28
- Southwest Bay of Bengal, Gulf of Mannar, Comorin area, and Tamil Nadu-Sri Lanka coasts until November 29
- Westcentral Bay of Bengal and Andhra Pradesh coasts from November 27 to 30
- Southeast Arabian Sea, Lakshadweep, Maldives, and Kerala coast from November 25 to 27
Fishermen already at sea in vulnerable regions, particularly near the Andhra Pradesh coast, have been instructed to return to shore before November 28. The IMD emphasized that offshore and deep-sea conditions will be extremely hazardous for small vessels due to gale-force winds and high waves.
Temperature Drop and Fog Conditions Ahead
A noticeable change in minimum temperatures is expected across northwest India, with the IMD predicting a gradual fall of 2-3 degrees Celsius between November 25 and 27. This temperature decline will be most apparent in states including Rajasthan, Punjab, Haryana, Delhi, and western Uttar Pradesh.
Central India will maintain relatively stable temperatures until November 26, after which night temperatures are forecast to drop by 2-3 degrees Celsius from November 27 to 29. Most other regions of the country are not expected to experience significant temperature variations during this period.
On November 25, isolated areas of west Uttar Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura may experience dense fog during nighttime and early morning hours. The reduced visibility could lead to flight operation delays, slower road traffic, and disruption of morning commutes.
Potential Impacts and Safety Advisories
The IMD has warned of possible localized flooding, waterlogging, traffic disruption, and temporary road closures in regions expecting very heavy rainfall. Urban centers might experience significant delays due to inundated roads, while damage to kutcha roads, vulnerable structures, and standing crops is possible in areas with persistent water accumulation.
Residents are advised to avoid waterlogged areas, check traffic conditions before traveling, and follow local advisories. The weather bulletin also highlights the potential for localized landslides or mudslides, particularly in hilly regions of Tamil Nadu and the Andaman Islands.
Throughout the seven-day period, rainfall intensity will transition from widespread moderate showers to heavy and very heavy spells, with thunderstorms being most frequent between November 25 and 28. Sea conditions will remain rough for most of the week, posing continued risks to maritime activities.
