Pune to have partly cloudy Diwali evening, rain expected later this week | Pune News

“IMD has issued a yellow alert for Vidarbha and some other parts, but that is because thunderstorms are expected in isolated places. No severe weather event, such as flooding, is expected,” said S D Sanap, scientist with IMD Pune.

He added that October, November and December are the months when cyclones form in the north Indian Ocean, i.e. the Bay of Bengal and Arabian Sea.

“Whenever they are moving in certain directions, the region experiences the weather associated with it. The Southern peninsular India and the East Indian region experience cyclones at times and low-pressure systems,” explained Sanap.

Anupam Kashyapi, Former IMD head weather forecaster and crop advisor, stated that there is a well-marked low-pressure system in the southeast-Arabian Sea at present that is likely to intensify and move west-northwestwards. “Another low-pressure area is forming in the Southeast Bay of Bengal that is likely to intensify and move west-northwestward, bringing moisture to the region of Vidarbha and south Maharashtra. This is likely to be the reason for the partly cloudy skies and isolated to scattered rain with thunder, lightning from the afternoon of October 20 for three or four days in these parts,” said Kashyapi.

Pune has been experiencing several days without rain, with temperatures ranging between 19 degree Celsius and 32 degree Celsius. The rise in day temperature is a normal occurrence that follows the withdrawal of the South-West Monsoon from the state. The rise in day temperature is a normal occurrence that follows the withdrawal of the South-West Monsoon from the state, because there is little lingering moisture in the air. This phenomenon is known as ‘October Heat’.

“Now, due to the low-pressure systems forming over the Bay of Bengal, moisture is entering through the easterly winds, resulting in the skies turning partly cloudy and light or scattered rainfall towards the afternoons and evenings,” said Kashyapi.
