As per the RMC, a low-pressure area is currently located over the southeast Arabian Sea, while an upper-air circulation is affecting the southern Andaman Sea and the nearby southeast Bay of Bengal.
This system is projected to strengthen into a low-pressure area within the next 24 hours and shift west-northwestward, gaining strength over the southwest and west-central Bay of Bengal in the subsequent 48 hours.
Consequently, the weather office has issued an orange alert for seven districts: Ramanathapuram, Pudukkottai, Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, and Cuddalore, warning of exceedingly heavy rain on Monday (October 21).
