There’s a successor waiting further West over East Afghanistan, with a third one expected to come into the reckoning by February 28.
An offspring cyclonic circulation over south-west Rajasthan is setting up most of the violent weather over the western half of North India, while a line-up of troughs left behind by away-going disturbances is doing the honours over the eastern half.

Troughs in East

Apec’s forecast
