LUCKNOW, Oct. 28 -- : Unseasonal rain accompanied by strong winds is expected in the state between October 28 and 31 due to the impact of an 'extremely severe cyclonic storm' called Arnab that has formed over the Bay of Bengal, said a weatherman on Tuesday. The IMD has issued an orange alert for 40 districts of Uttar Pradesh on Thursday and Friday (October 29 and 30}) to brace for the impact of 'Arnab'. This is the second-highest level in the IMD's four-stage colour-coded weather warning system (Green, Yellow, Orange, Red) which means 'be prepared'. Apart from that, the IMD has issued a yellow alert for Lucknow, Kanpur city, Unnao and nearby areas as there is a likelihood of thunderstorms and lightning accompanied by gusty winds (at speeds of 40-50 km/h) on Thursday and Friday.

It is likely to cause a significant drop in day temperatures by 6-9degC....
