This year, most areas of South Peninsula received good rains. In fact, only three meteorological divisions are rain-deficient as of now. Currently, Rayalaseema is the most deficient at 45%, while North Interior Karnataka is rain deficient by 21% and Lakshadweep is 43% deficient. Rest of the regions in Southern Peninsular India are in the normal category.
The state of Kerala has received excess rainfall during this Monsoon and is 34% surplus. This had led to extreme flooding conditions in the state last month and was considered the worst floods in Kerala in nearly a century with over 483 people dead and 14, still missing.
As we do not expect the formation of any significant weather system over Southeast Arabian Sea or South Bay of Bengal, now, subdued Monsoon conditions will continue over the entire South Peninsula for at least one week. This will lead to the rain deficiency of Rayalaseema, North Interior Karnataka to increase further and other areas will also witness a dip in rain.
Indian Monsoon arrives in two phases, the first phase is known as the Southwest Monsoon and the second phase is known as the Northeast Monsoon. Monsoon starts withdrawing from Northwest India after September 1 and Northeast monsoon commences over the South Peninsula by the beginning of October. Therefore, we do not expect any significant rain activity over South India until the onset of the Northeast monsoon.
