Southwest monsoon (June-September), which officially ended on September 30, has been weak for the Telugu states. Though the deficit was high during July-August, a deep depression over the Bay of Bengal in the last week of September improved the rainfall scenario.

Three low-pressure systems formed during September, of which two intensified into the Deep Depression category. These systems contributed to good rainfall over parts of Peninsular and Central India, as well as the Indo-Gangetic Plains.
The rainfall over the south Peninsular India during the post-monsoon season (October to December is most likely to be normal (88-112 per cent of LPA).
The LPA of rainfall over South Peninsular India during the post-monsoon season based on data from 1971 to 2020 is about 334.13mm.
