Chennai, Feb 14 || A low-pressure area is likely to form over the Bay of Bengal on Saturday, according to a weather bulletin issued by the Regional Meteorological Centre (RMC), Chennai.
The development is attributed to an upper-air cyclonic circulation prevailing over the east-central Indian Ocean and adjoining southeast Bay of Bengal, which is expected to intensify into a low-pressure system.
In its latest advisory, the weather department stated that atmospheric conditions are becoming favourable for the formation of the system. While no immediate heavy rainfall warning has been issued, meteorologists are closely monitoring the evolving weather pattern over the Bay, as such systems can influence rainfall and wind conditions over coastal Tamil Nadu in the coming days.
Meanwhile, several districts in Tamil Nadu are expected to experience foggy conditions.
On Friday, light fog is likely to occur in at least 13 districts, including Chennai, Tiruvallur, Kancheepuram, Chengalpattu, Krishnagiri, Dharmapuri, Salem, Namakkal, Dindigul, The Nilgiris, Ranipet, Vellore and Tirupattur.
The RMC has further forecast moderate fog in Chennai, Tiruvallur and Chengalpattu districts on Saturday morning.
