Overview of the Changing Weather Pattern
Large parts of the country are set for a mix of sharp temperature drops and widespread rain over the next few days.
The India Meteorological Department has indicated that sections of West Madhya Pradesh may continue to face intense cold
on 20 November, while some areas could see milder cold on 21 November. Similar chilly conditions are expected across
Madhya Maharashtra, East Madhya Pradesh and Telangana on 20 November.
The southern and island regions are preparing for significant rainfall too. The Andaman and Nicobar Islands are expected
to receive heavy to very heavy rain on 21 November, while several southern states will see prolonged wet spells
stretching through the week.
Rainfall Outlook for Southern and Island Regions
Rain will continue to dominate over Tamil Nadu until 25 November, with occasional strong spells. Kerala and Mahe are likely
to see intermittent rain today and again between 21 and 24 November. Lakshadweep can expect a wet day today, while
Coastal Andhra Pradesh, Yanam and Rayalaseema may get showers on 25 November. The Andaman and Nicobar group is heading
for a rainy stretch from 19 to 23 November, with exceptionally heavy showers projected for 21 November.
Recent Weather Highlights
During the last 24 hours, a few pockets of Tamil Nadu recorded extremely intense showers above 21 cm. Several parts of
Kerala and Lakshadweep also saw heavy to very heavy rain. Cold wave conditions persisted in parts of Maharashtra and both
East and West Madhya Pradesh, along with Telangana. Dense fog was observed in Odisha, while milder fog appeared in Assam,
Meghalaya, Tripura and Himachal Pradesh.
Systems Driving the Current Weather
A low pressure system that developed near the Comorin region has now shifted closer to Lakshadweep and the Maldives.
Its associated wind pattern extends into the middle atmospheric layers and is expected to drift slowly west-northwest.
Another circulation remains active over the southwest Bay of Bengal.
From 22 November, a fresh low pressure system is likely to form over the southeast Bay of Bengal. This system may grow
stronger and turn into a depression by 24 November while moving toward the central parts of the southern Bay. It could
intensify further as it progresses into the southwest Bay during the next two days.
Thunderstorms and Temperature Trends
Lightning and thunderstorms may occur frequently in Tamil Nadu until 23 November. Kerala, Mahe and Lakshadweep may also
experience similar activity for short periods. Parts of Coastal Andhra Pradesh, Yanam and Rayalaseema may see thunder
between 21 and 23 November.
Minimum temperatures across northern and central India have dipped sharply. Some areas of Jammu and Kashmir, Ladakh and
Gilgit-Baltistan reported values below 6°C. Punjab, East Rajasthan and regions of Haryana and Delhi recorded temperatures
between 7°C and 10°C. The lowest temperature reported over the plains was 5.5°C in Sikar, East Rajasthan.
Expected Temperature Movement
Central India may see a gradual 2°C to 4°C rise in minimum temperatures over the next five days. Northwest India is
expected to witness no major change during the coming week. Maharashtra and Gujarat may also warm slightly over the
next four to five days. Eastern India could experience a small temperature increase over the next two days.
What Fishermen Should Know
Fishermen have been advised to avoid several maritime regions from 19 to 24 November. Unsafe zones include the Arabian Sea
near the south Kerala coast, Lakshadweep, Maldives and the Comorin area today. Hazardous sea conditions are also expected
across parts of the Bay of Bengal, especially the Gulf of Mannar, southeast Bay regions, east central Bay and the Andaman
Sea on specific dates during this period.
Delhi Weather Outlook for 19–22 November
Delhi is likely to remain mostly clear through the week with light fog during early mornings. Temperatures will stay
slightly below seasonal norms, with daytime levels between 25°C and 28°C and night temperatures ranging from 9°C to
12°C. Winds will remain calm during mornings and become gentle through the afternoons, mainly from the north and
northwest.
Expected Impact of Heavy Rain and Cold Conditions
The heavy rain predicted for the Andaman and Nicobar Islands on 21 November may lead to waterlogging, reduced visibility
and minor damage to roads and crops. Communities in low-lying areas are advised to stay alert.
Cold wave conditions in parts of West Madhya Pradesh on 20 November may trigger discomfort, frost-like symptoms and
health risks linked to prolonged cold exposure. People are encouraged to stay warm, limit outdoor activity, use safe
heating options and take extra care of vulnerable individuals and livestock.
Agriculture and Livestock Advice
Farmers in Tamil Nadu, Kerala and the Andaman and Nicobar Islands are advised to safeguard harvested produce and drain
excess water from crop fields. Support for banana and other tall crops is essential to prevent lodging. Sowing in heavy
rainfall zones should be avoided for now.
Livestock keepers should ensure dry shelter, proper ventilation and secure storage of fodder during this wet and cold
spell.
