After the deluge caused by Cyclone Fengal, Tamil Nadu finds itself bracing for another weather event. A low-pressure system has developed in the southwest Bay of Bengal, currently situated east of Sri Lanka. This system is showing signs of strengthening, with increasing convection near its center and a gradual reduction in wind shear. There is a moderate possibility of the system intensifying into a depression as it tracks west-northwest towards the Tamil Nadu and Andhra Pradesh coasts.
Expected Landfall and Rainfall Impact
The system is projected to make landfall between Nagapattinam and Ramanathapuram on December 12th or 13th, likely as a low-pressure area or a depression. Under its influence, Tamil Nadu and parts of southern Andhra Pradesh are expected to experience widespread moderate to heavy rainfall over the next few days, up to December 14th or 15th.
Key Areas to Watch
Regions along the Puducherry-Nagapattinam-Ramanathapuram belt in Tamil Nadu and southern districts of Andhra Pradesh are particularly vulnerable to intense rainfall during this period. Local authorities and residents in these areas should remain alert for potential flooding and waterlogging.
Northeast Monsoon Update
The active phase of the Madden-Julian Oscillation (MJO) over the Maritime Continent and the western Pacific is enhancing northeast monsoon activity. This could pave the way for another low-pressure area to form in the Bay of Bengal next week, with potential impacts on Tamil Nadu and Andhra Pradesh around December 16th to 19th. Further updates on this developing system will follow.
Preparedness and Safety Tips
- Monitor Weather Updates: Stay tuned to official weather bulletins for the latest forecasts and warnings.
- Emergency Kits: Prepare emergency kits with essentials like food, water, flashlights, and medicines.
- Avoid Travel: Refrain from non-essential travel during heavy rain periods, especially in vulnerable areas.
- Local Authorities: Follow instructions from local authorities regarding evacuations and safety measures.
As Tamil Nadu and Andhra Pradesh continue to recover from Cyclone Fengal’s impact, proactive measures and timely information will be crucial in mitigating the effects of this emerging weather system. Stay safe and prepared for the days ahead.
