Chennai, Nov 25
With a heavy rain forecast from Wednesday onwards in many districts of Tamil Nadu, the Regional Meteorological Centre (RMC) was expected to issue a red alert for the Delta districts on Thursday and Friday (November 28 and 29).
The weather department has already issued an orange alert for Chennai, Karaikal, and Puducherry on Monday.
The state was bracing for heavy to very heavy rainfall over the next few days.
The RMC, in a statement on Monday, said that a depression over the southeast Bay of Bengal was expected to intensify into a deep depression. It is anticipated to strengthen further as it moves northwestward.
The Delta districts of Tamil Nadu were likely to experience heavy to very heavy rainfall during this period.
The RMC has also issued an advisory for fishermen, urging them to refrain from deep-sea fishing between November 25 and 28 due to the depression over the central parts of the southern Bay of Bengal.
A new low-pressure area, which formed over the East Equatorial Indian Ocean and adjoining Southeast Bay of Bengal on Saturday morning, was expected to bring heavy rain to the Delta region, Chennai, surrounding districts, and the southern parts of Tamil Nadu.
