Many schools reopened on Monday after the Durga Puja vacation and students were inconvenienced due to the heavy rain. The Weather Department said the inclement weather was triggered by a deep depression.
The reason for good spells of rains over the area was the existence of deep depression that was persisting over Gangetic West Bengal. The condition of the sea off the coast of Odisha will be rough and fishermen have been advised against venturing into the waters. "The deep depression is likely to weaken into a depression and then into a well-marked low pressure and continue to move in a west-northwestward direction towards the Jharkhand border", Das said.
Squally wind speed reaching 40-50 kmph gusting to 60 kmph would prevail over Gangetic West Bengal and 30-40 kmph gusting to 50 kmph very likely over adjoining areas of Jharkhand during next 12 hours and gradually decrease thereafter.
"Due to heavy rain and strong wind in Panagarh-Asansol-Sitarampur section of Eastern Railway?s Asansol Division, train services in the section were affected today", Eastern Railway spokesman R N Mahapatra said.

"All trains of South Eastern Railway are running as per schedule and there is no disruption so far", SER spokesman Sanjoy Ghosh said.
