Heavy rainfall is likely at isolated places over Tamil Nadu and Kerala on April 22 and 23 as part of a wet spell during the next 5 days due to a western disturbance, according to a forecast by the weather office.

“Light isolated to scattered rainfall with thunderstorms, gusty winds very likely over Andhra Pradesh, Telangana, Interior Karnataka, Tamil Nadu, Puducherry & Karaikal and Kerala during next 5 days,” India Meteorological Department (IMD) said.

A cyclonic circulation lies over northwest Madhya Pradesh and another over interior Tamil Nadu in lower levels. This has been created by a western disturbance which is an extratropical storm originating in the Mediterranean region that brings sudden rain to the Indian subcontinent.

Apart from the peninsular region, IMD has also predicted a wet spell for Madhya Pradesh and Maharashtra and northeast India for the next four days.

Hailstorms are very likely at isolated places over Sub-Himalayan West Bengal and Sikkim on Saturday, over Odisha during till April 24 and over Bihar on April 24 and 25, according to the forecast.

Meanwhile, there will be no heatwave over most parts of the country during the next five days, it added.
