  10. “A low pressure area is predicted to form on the Bay of Bengal coast around November 8 or November 9. This could intensify and lead to a wet Diwali,“ said Regional Meteorological Centre deputy director general S B Thampi.

    According to independent weather blogger Pradeep John, the sea temperature and wind shear is poised to form a system near the Andaman coast. “The surface sea temperature is high at 30°C and it is being accompanied by low wind shear. According to numerical weather models, we are expecting a rapid intensification of a low pressure system that could bring plenty of rain to the city any time soon,“ John said.
