According to the India Meteorological Department (IMD), the strong lower-level south-westerly winds blowing in from the Bay of Bengal, coupled with other favourable meteorological conditions, will cause rainfall, thunderstorms, hailstorms, thundersquall and lightning over the Northeast for the next two days, i.e. March 31 and April 1.
Fairly widespread to widespread showers, thunderstorms, hailstorms, thundersquall and lightning are all expected at isolated places across Northeast India on Wednesday and Thursday, although maximum rainfall activity is expected on Wednesday itself.
Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura will all witness isolated heavy falls on Wednesday, whereas Arunachal Pradesh and Sikkim will be in for heavy downpour on Wednesday as well as Thursday.
As per The Weather Channel’s met team, a 3-day total precipitation of 50 mm to 120 mm is possible over Arunachal Pradesh and adjoining areas from Wednesday to Friday.
According to Hindustan Times, dry, dust laden winds from Rajasthan have started blowing over Delhi leading to a deterioration in air quality and visibility in the Capital.
The average air quality index on Tuesday was recorded at 232, in the “poor” category. The concentrations of PM 10 (coarse pollution particles) spiked from 224 micrograms per cubic metres to 326 micrograms per cubic metres at 4pm, according to data with the Central Pollution Control Board.
The PM 10 concentration at 9pm was 361.1 micrograms per cubic metres. The 24-hour safe standard for PM10 as per CPCB is 100 micrograms per cubic metres.
Scientists from the India Meteorological Department said the air quality is likely to deteriorate further as strong, westerly winds is likely to blow over the city till April 1.
“The change in the colour of the sky is mainly due to dust. There is loose soil floating around and strong winds is raising this soil and dust particles. Westerly winds, which is blowing at about 40kmph, is also bringing dust from Rajasthan. These conditions will continue till April 1, following which temperature will rise further,” said Kuldeep Shrivastava, head, regional weather forecasting centre.
The relative humidity was only 16% to 17% on Tuesday afternoon.
According to IMD scientists, dust raising winds are affecting the entire Indo-Gangetic Plains region.
“Our models are showing that these strong winds will prevail for 2-3 days. There is no moisture incursion over the region. Winds are blowing from dry regions to the west and northwest. Heat wave conditions were recorded over parts of Uttar Pradesh, Rajasthan, Gujarat, Madhya Pradesh and Delhi on Monday because of clear skies, uninterrupted solar radiation and low wind speed. But the strong winds will help keep the maximum temperature in check for now. Maximum temperatures will shoot up again from April 2 or April 3,” said K Sathi Devi, head, national weather forecasting centre.
5-Day Nationwide Forecast
According to Weather.com, under the influence of the cyclonic circulation over Southeast Bay of Bengal and adjoining south Andaman Sea, a low pressure area has formed over the same region. The associated cyclonic circulation extends up to 5.8 km above mean sea level, and is likely to become more marked over North Andaman Sea and neighbourhood during the next 24 hours, as per the India Meteorological Department (IMD).
This system will cause widespread rainfall with thunderstorms, lightning and gusty winds over Andaman & Nicobar Islands during the next four days. Isolated heavy to very heavy falls are also on the cards over the Islands during March 31-April 1. Fishermen are also advised not to venture into Southeast Bay of Bengal and adjoining South Andaman Sea on March 31, and over the Andaman Sea and adjoining areas of Bay of Bengal on April 1-2.
Meanwhile, strong lower level south-westerlies from the Bay of Bengal and other favourable meteorological conditions are set to bring fairly widespread to widespread rainfall with thunderstorms, hailstorms, thundersquall and lightning at isolated places of Northeast India on March 31-April 1, with maximum activity on March 31.
Accordingly, isolated heavy falls are expected over Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura on March 31, and over Arunachal Pradesh during March 31-April 1. These conditions may also cause landslides and inundation of low lying areas at isolated places over south Assam, Meghalaya, Tripura and Mizoram during March 31-April 1. 3-day total precipitation of 50 mm to 120 mm is possible over Arunachal Pradesh and adjoining areas from Wednesday to Friday.
A trough and cyclonic circulation also persist over Southern India, which will bring isolated to scattered rain with lightning over Kerala in this period.

Lastly, a fresh western disturbance could affect the Western Himalayan Region from Sunday onwards. Dry weather is likely over Central, Western and Eastern India in this period, and over Northern India from Wednesday to Saturday.
As for mercury levels, heatwave conditions are possible in isolated pockets over East Uttar Pradesh, Bihar, East Madhya Pradesh, Chhattisgarh, Rajasthan, Maharashtra, Jharkhand, West Bengal, Odisha and Telangana on Wednesday, and in isolated pockets over Maharashtra, Odisha and Telangana on Thursday.
However, the maximum temperatures are very likely to fall by 3-5°C over the plains of Northwest India during the next two days, leading to the abatement of heatwave conditions over Rajasthan. Although, another heatwave spell is expected over the plains of Northwest India from April 3.
The maximum temperatures will be below normal over Northeastern India in this period due to rainfall, near-normal or slightly below normal over Eastern and Northern India from Thursday onwards, and slightly higher than average over Western and Southern India in this period.
Dust-raising strong surface winds (speed reaching 30-40 kmph) are very likely to prevail over Rajasthan, Haryana, Delhi, West Uttar Pradesh, Punjab, north Madhya Pradesh, East Uttar Pradesh, Jharkhand and Gangetic West Bengal during March 31-April 1.
