Chennai: A low-pressure area is expected to take shape over the Bay of Bengal on Saturday, the Regional Meteorological Centre (RMC), Chennai, said in a weather bulletin.

The anticipated system is linked to an upper-air cyclonic circulation currently positioned over the east-central Indian Ocean and the adjoining southeast Bay of Bengal. Meteorologists said this circulation is likely to strengthen and develop into a low-pressure system.

In its latest advisory, the weather department observed that atmospheric conditions are turning favourable for the system’s formation. No warning of heavy rainfall has been issued at present. However, officials are closely tracking the developing weather pattern over the Bay, as such systems can alter rainfall and wind conditions along coastal Tamil Nadu in the coming days.

Meanwhile, several districts in Tamil Nadu are expected to experience foggy conditions.

The RMC has further forecast moderate fog in Chennai, Tiruvallur and Chengalpattu districts on Saturday morning.

Motorists have been advised to exercise caution during early morning hours due to potential low visibility in these regions.

In addition to fog, temperatures are expected to rise gradually across Tamil Nadu, Puducherry and Karaikal over the next 24 hours.

The weather department noted that maximum temperatures may increase by a few degrees Celsius, particularly in interior districts.

Residents are advised to stay hydrated and avoid prolonged exposure to direct sunlight during peak afternoon hours. Weather officials said further updates will be issued as the situation over the Bay of Bengal becomes clearer.

Fishermen and coastal residents have been advised to keep track of official advisories in view of the possible formation of the low-pressure area.

The formation of a low-pressure system over the Bay of Bengal during this time of the year is not uncommon, but its intensity and movement will determine its eventual impact on Tamil Nadu and neighbouring regions.
