The wet southerly winds from the Bay of Bengal will extend the rainfall to southern Central India and then East India over the weekend.
The weather forecast also predicts heavy rain over Northeast India, caused by another trough lying in that region. A third trough, present over northern Central India, along with approaching Western Disturbances, is expected to produce light to moderate rain across the northern plains, including NCR, for several days, starting from April 30.
In East India, scattered or fairly widespread rainfall with thunderstorms, lightning, and gusty winds are very likely to occur.
