Both Gangetic West Bengal and Bihar, according to the India Meteorological Department (IMD), are anticipated to experience heatwave conditions in some regions and severe heatwave conditions in isolated areas over the next 24 hours. Following that, isolated regions of both states will see hot conditions on Thursday and Friday, April 20-21.
When the local temperature is projected to exceed 40°C while also rising 5°C to 6°C over the region's typical temperature, the IMD declares a heatwave. A severe heatwave is declared when the temperature is expected to exceed the average by 7°C or more.
Given these forecasts, both states have issued an orange alert ('be prepared' for severe weather) for today and a yellow watch ('be aware' of local weather conditions) for tomorrow and the following day.
Severe heatwaves are expected in Patna, East Champaran, Khagaria, and Banka districts in Bihar, and Purulia, Bankura, and Paschim Bardhaman districts in West Bengal. As a result, an orange alert has been issued for these areas on Wednesday.
Physical exertion, discomfort, dehydration, heat cramps, heat exhaustion, and heat strokes are all real risks in such heatwave circumstances.
As a result, people of the region, particularly youngsters, the elderly, and those with pre-existing morbidities, should avoid going outside, particularly in the afternoon. If going out is inevitable, remain hydrated and choose breathable, lightweight clothing made of natural fibres.
According to the IMD forecast, these hot conditions are likely to last until Friday, when unseasonal storms are expected to help temper the area weather.
Light rains, thunderstorms, and lightning appear to be on the way for West Bengal, Bihar, and its surrounding states of Jharkhand and Odisha beginning April 21.
