The influence of a persisting low-pressure area over North Bangladesh and adjoining West Bengal is largely being confined to Northeast India.
This trend is likely to hold for the next two days, according to an India Met Department outlook posted this morning.
The localised extremely heavy rainfall pattern for wet spot Cherrapunji in Meghalaya continued through the day yesterday when the town recorded 15 cm until 5.30 pm.
This came on the back of the 38 cm recorded during the 24 hours ending at 8.30 am yesterday morning.
The Met forecast for today said that heavy to very heavy rainfall would occur at a few places over Assam and Meghalaya and at isolated places over Arunachal Pradesh today.
Heavy rainfall is also forecast for isolated places over Sub-Himalayan West Bengal, Sikkim, Nagaland, Manipur, Mizoram and Tripura.
HEAVY IN EAST
As for tomorrow, heavy to very heavy rainfall has been forecast at a few places over Assam and Meghalaya and at isolated places over Arunachal Pradesh.
Heavy rainfall would occur at isolated places over Sub-Himalayan West Bengal, Sikkim, Nagaland, Manipur, Mizoram and Tripura.
Meanwhile, the feeble southeasterly winds from the Bay pushed in by the 'low' has been triggering thunderstorms over the plains of East and Northwest India over the past few days.
This has helped bring the peak mercury to manageable levels in the region, including in the national capital.
THUNDERSTORM FORECAST
Thunderstorms are forecast to break out over the region from this morning also.
The thunderstorm alert for today covers regions extending from Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Delhi, Chandigarh, North Rajasthan, Uttar Pradesh, Assam, Meghalaya, West Bengal, Sikkim, Tripura, Jharkhand and Odisha to coastal Andhra Pradesh and Tamil Nadu.
