Assam, May 1: A trough stretching east-westward over central India attracts moisture from the Bay of Bengal to eastern and northeastern India during this forecast period, leading to heavy rainfall with thunderstorms across the regions.
Total rainfall accumulation of 100-150 mm in five days is forecast for Assam and adjoining areas. As per the India Meteorological Department (IMD), isolated heavy rains are likely over Assam and Meghalaya from May 1 to 3, over Nagaland, Manipur, Tripura, and Mizoram on May 3 and 4, and over Odisha, Sikkim, and West Bengal from May 3 to 5.
A cyclonic circulation over southern India will produce rain with thunderstorms across Kerala and adjoining areas throughout this period. Isolated heavy rains are likely over Kerala between May 1 and 4, over coastal Andhra Pradesh on May 3, and over the southern interiors of Karnataka on May 4.
Maximum temperatures will be above normal across North India throughout the next five days and above normal over northeast India over the next 2-3 days. Daytime temperatures could be well below normal across much of eastern India later in the forecast period.
Minimum temperatures will be well above normal over northern India and above normal across the Arabian Sea coast during this period. Due to prevailing thunderstorm activities across the country, now significant heatwave conditions are expected during this period by the forecasters.
