It seems like May is about to bring some good news for East India. A rainy spell is approaching Jharkhand, West Bengal and Bihar commencing today. The intensity of the rains is likely to increase by tomorrow and will continue for two days.

East India is prone to Nor’westers during the Pre-Monsoon season. Thunderstorms develop over the Chhotanagpur region and travel up to Kolkata resulting in rains accompanied by strong winds over the area. However, these activities are highly localized in nature.
