In Short

  • Rainfall expected in Andaman and Nicobar Islands due to Bay of Bengal system
  • Dry weather likely in northwest, central and western India on Friday
  • Delhi to experience dip in night temperatures mid-next week with winter chill

Weather conditions across India are set to see varying developments on Friday, November 13, as a developing system over the Bay of Bengal is expected to bring rainfall to the Andaman and Nicobar Islands, while parts of northern India remain under the influence of a fresh spell of showers.

The India Meteorological Department (IMD), in its latest weather forecast, said the system over the southeast Bay of Bengal could strengthen over the next few days, making it the key weather development to watch.

Meanwhile, most parts of northwest, central and western India, including Delhi, Haryana, Rajasthan and Uttar Pradesh, are expected to experience largely dry weather on Friday.

However, temperatures in the national capital are forecast to dip next week, bringing the seasonal winter chill.

RAIN AND THUNDERSTORMS TO ARRIVE

The IMD has forecast fairly widespread to widespread rainfall over Jammu and Kashmir, Ladakh and adjoining areas on November 13.

Isolated to scattered rainfall is also expected over Himachal Pradesh and Uttarakhand, while Punjab could receive isolated showers.

Thunderstorms accompanied by lightning and gusty winds reaching 40-50 kmph are likely at isolated places over Jammu and Kashmir and adjoining areas.

Himachal Pradesh could also experience isolated thunderstorms and lightning.

BAY OF BENGAL SYSTEM TO INTENSIFY

The more significant development is unfolding over the Bay of Bengal, where a low-pressure area is likely to form over the southeast Bay around November 13.

According to the IMD, the system is expected to move northwestwards and intensify into a well-marked low-pressure area around November 14, before potentially developing into a depression around November 15.

A low-pressure area is a region where atmospheric pressure is lower than its surroundings. It encourages winds to converge, potentially generating rain-bearing clouds. If it strengthens, it can bring more organised rainfall and stronger winds.

The Andaman and Nicobar Islands are likely to receive fairly widespread to widespread rainfall on November 13, with isolated heavy rainfall, thunderstorms, lightning and gusty winds.

WILL IT GET COLDER?

While a widespread temperature drop is not expected immediately, the IMD has forecast a gradual rise of around 2°C in Delhi's night temperatures on November 13 and 14, followed by little change on November 15.

However, colder conditions could return towards the middle of next week, with minimum temperatures expected to fall by 3–5°C between November 16 and 19.

This could bring a more noticeable chill to Delhi and adjoining areas as winter gradually sets in.
