India's Prolonged Monsoon: Rainfall Expected Through Year End
The usual rainy season in India is lasting longer than usual.
This is because of weather patterns in the Bay of Bengal and the Indian Ocean.
This means some parts of India will keep getting rain, even as others dry out.
The northeast of India will get a lot of rain in October through December.
People in the south need to get ready for strong storms.
Cities should keep their drains clear.
This means that even though the main rainy season is ending, rain will still be happening in some places through the end of the year.
The southwest monsoon is retreating slowly, extending the rainy season.
Low-pressure systems in the Bay of Bengal are driving the prolonged rainfall.
A negative Indian Ocean Dipole is contributing to the wetter conditions.
Central and peninsular India will see rainfall extending into late September.
The northeast monsoon will bring rain to the south from October to December.
