As many as 22 districts in the State are likely to receive heavy to very heavy rainfall on Thursday due to a depression near Cape Comorin.
This weather system is likely to become a deep depression by Wednesday night and further intensify into a cyclonic storm by Thursday or Friday.
These districts would have rainfall between 7 cm and 24 cm on Thursday. “The weather system may have an impact over the State till Friday after which the rainfall may start to reduce,” said S. Balachandran, Deputy Director General of Meteorology, Chennai.
As the system is likely to move across Lakshadweep islands, heavy rainfall would be restricted to a few places in the State from Thursday afternoon. From November 1, rainfall would begin to steadily decrease. “If the weather disturbance becomes cyclonic storm, it may be called Maha , a name given by Oman,” he said.
Heavy rains
Nearly 80 weather stations across the State received heavy to very heavy rains during the past 24 hours ending 8.30 a.m. on Wednesday.
Among the various places, Tiruttani registered a highest volume of 19 cm of rainfall in the State. This rainspell that covered a vast geographical space has helped boost the State’s seasonal average from a marginal deficit on Tuesday to slightly excess on Wednesday, Mr. Balachandran said.
