A change in wind direction from west to southwest will bring a momentary relief from the heat wave conditions as temperatures may go down during the next 24 hours. But thereafter, the heat wave in Delhi will continue with the least temperature at around 29 degrees in the morning hours and highest temperature of 45 degrees or more in different parts of the city.
Similar dry and hot conditions would prevail in most of the parts of north and northwest India. Some parts will continue to witness severe heat wave. They may bear dust-raising winds during the next two to three days.
Pre-monsoon rain will continue in east India over West Bengal, Sikkim, Bihar and Jharkhand for a couple of days. This rain will also remain intact over northeastern states. There will be rain at many places in northeast. The cyclonic circulation continues over Assam.
The trough of low pressure runs from east Uttar Pradesh to Tamil Nadu across Madhya Pradesh, Vidarbha and interior Andhra Pradesh. Owing to this seasonal weather system, rain at one or two places will occur in these areas.
Westerly winds from the Arabian Sea are turning into southwesterly winds right in the middle of lower south Peninsula over south interior Karnataka and adjoining Kerala and Tamil Nadu. Such curve in wind direction is creating chances of rain (mostly light) in these areas. One or two places like Chitradurga in Karnataka could get moderate to heavy rain during the period. This area has received heavy rain since Saturday.
