LUCKNOW: As dry hot westerly winds coming from deserts of Rajasthan continued to lash north India, the state was gripped by a severe heat wave. Almost all the districts of UP recorded hottest day of this summer on Monday. No respite is in sight as weatherman predicted that heat wave will continue for next 2-3 days. The monsoon has revived, but is still weak, hence chances of moisture laden currents reaching the state till June 25 seem bleak. The normal date of monsoon arrival in UP is June 15, but this year it has now been delayed by almost 12 days. Ideally, it should be raining at this point of time. Instead, the state is sizzling under heat wave. If Sultanpur recorded 46.2 degrees Celsius
