Weather Tomorrow: Met Department Forecasts Widespread Rain Across North India After Cyclone Arnab

Moderate rain is possible at isolated places in the morning. Maximum temperatures are likely to be 26-28 degrees Celsius, appreciably below normal, and minimums 16-18 degrees Celsius.

Fairly widespread to widespread rainfall is forecast over the Andaman and Nicobar Islands from October 28 to 31. Gangetic West Bengal and Jharkhand will see similar rain from October 28 to 30. Odisha is expected to see it on October 28-29.
