"But due to the formation of two low-pressure areas, the easterlies will travel all the way to Rajasthan.
So, the withdrawal of monsoon
from west Rajasthan
is unlikely to happen until September 24, IMD director general Mrutunjay Mohapatra said.
A low-pressure area has formed off the coast of Andhra Pradesh, while another one is expected to form by September 20, Mohapatra added.
The IMD has also issued an orange colour alert for peninsular India.
"A low-pressure area lies over the west-central Bay of Bengal off north Andhra Pradesh coast," the IMD said.
"It is likely to move west-northwestwards towards central India across Telangana during the next 2-3 days. The monsoon trough lies south of its normal position. An off-shore trough lies off south Gujarat coast to north Karnataka coast," it said.
Due to this, widespread rainfall with isolated heavy to very heavy showers are very likely over coastal Andhra Pradesh, Yanam and Telangana on September 13 and 14, over Vidarbha on September 15 and over Marathwada on September 16, the IMD added.
