Red alert in 3 Kerala districts The Chief Minister's Office in Kerala stated that the India Meteorological Department (IMD) has predicted that the formation of a low-pressure area over Southeast Arabian Sea tomorrow is very likely. "It is likely to concentrate into a depression & move Northwestwards during the subsequent 48 hrs. It is also likely to intensify into a cyclonic storm thereafter," the CMO says. The government has decided to take precautionary measures on a war footing and directions have been issued to the district collectors. "No one must venture into seas after October 4th. This information will be communicated to people in coastal areas using loudspeakers and other facilities. The low pressure will cause strong winds & rough sea. Hence, the fishermen who had gone to sea were advised to reach the safest coastline before October 5," the Chief Minister's Office has warned. "IMD issued red alerts in 3 districts of Central Kerala Idukki, Palakkad and Thrissur along with several parts of the state on October 7. Most parts of Kerala will see heavy rainfall by October 5," the CMO stated.
