Tamil Nadu’s weather narrative is flipping from drought-like dryness to deluge as a potent low-pressure zone in the Bay of Bengal gathers force. The RMC in Chennai forecasts heavy rains battering 10 key districts on February 21, urging widespread preparedness.
This cyclonic circulation over the west-central Bay of Bengal and south-east Arabian Sea is strengthening progressively. Statewide aridity persists through February 18, but southern coastal and Delta zones may see initial light-to-moderate precipitation on February 19.
Escalation hits February 20 with moderate rains spanning Tamil Nadu and Puducherry. The climax unfolds February 21: heavy falls in Mayiladuthurai, Nagapattinam, Thiruvarur, Thanjavur, and Pudukkottai of the Delta; isolated heavy showers in southern Ramanathapuram, Thoothukudi, Tirunelveli, Kanyakumari, and Tenkasi.
February 22 brings squally weather with thunder and heavy rain to Tenkasi, Tirunelveli, and Kanyakumari. Fishermen are strictly advised against sea voyages in southern waters due to hazardous conditions. Flood-vulnerable communities in lowlands should stock essentials, monitor updates, and comply with evacuation orders if needed.
As this system tracks closer, it promises much-needed moisture but carries perils of urban flooding and crop damage. Vigilant oversight by meteorological authorities will be crucial in navigating this volatile weather shift.
