New Delhi

Heat wave conditions prevailed over most parts of Haryana, and Delhi, in many parts over south Uttar Pradesh, in some parts over Jammu division, Himachal Pradesh, west Rajasthan, and Punjab and at isolated parts over east Rajasthan and over north Madhya Pradesh on Sunday with Uttar Pradesh's Banda registering highest maximum temperature at 49 degrees Celsius.

Heat wave conditions were observed in many parts over Vidarbha and at isolated pockets over southwest Bihar and Jharkhand, the India Meteorology Department (IMD) said and predicted no significant change in maximum temperatures over many parts of NW India and central India on Monday but fall by 2-4 degrees Celsius during subsequent two days.

The IMD bulletin said there would be reduction in intensity and spatial distribution after Monday as heat wave to severe heat wave conditions would prevail in many parts very likely over isolated pockets over south Uttar Pradesh on Monday. In the meanwhile the IMD has predicted isolated extreme rainfall is likely during next two days over Kerala and heavy to very heavy rainfall during next three days while isolated heavy to very heavy rainfall, with extremely heavy rains too, is likely over Meghalaya till May 17.

India Meteorological Department said on Sunday, several districts in north-east India, especially Assam and Meghalaya, and almost all districts in Kerala received extreme downpours since Saturday. This has led to flood conditions at scores of places in both the regions.

The IMD bulletin also said that the advance of Southwest Monsoon into the South Andaman Sea, Nicobar Islands and adjoining Southeast Bay of Bengal will be during next 24 hours. "Due to strong equatorial flow from Bay of Bengal to Andaman Sea in lower tropospheric levels, widespread rainfall with isolated heavy falls and thunderstorm/lightning/gutsy winds are very likely over Andaman & Nicobar Islands during the next five days."
