Tuesday, August 2: The already-heavy rains that have been lashing Tamil Nadu and Puducherry all through last week are only likely to worsen, after favourable low-pressure systems and shear zones decided to take a group vacation in the southern areas of the country over the previous weekend.
This week, the same shear zone over south peninsular India as well as the north-south trough that now resides from south Chhattisgarh all the way to the Comorin area are likely to team up and continue dumping extraordinary amounts of moisture over the southernmost parts of the country.
As a result, the India Meteorological Department (IMD) has forecast fairly widespread to widespread showers accompanied by thunderstorms and lightning over Tamil Nadu and Puducherry till Friday (August 5).
While heavy to very heavy rains (64.5 mm-204 mm) will supplement the inclement weather in localised areas during this time period, there are additional chances of extremely heavy downpours (204 mm) ravaging the two southern regions on Tuesday and Wednesday (August 2-3).
As a result, the IMD has placed Tamil Nadu and Puducherry on a red warning (meaning ‘take action’) for the next 48 hours, following which it will likely be downgraded to an orange alert (meaning ‘be prepared’) for Thursday (August 4).
As for specific district-level warnings, the following areas will be under significant alerts over the next few days:
- Tuesday, August 2: Kanyakumari, Theni, Tenkasi and Tirunelveli on red warning; Dindigul, Tirupattar, Virudhunagar and Tiruppur on orange alert.
- Wednesday, August 3: Dindigul, Tiruppur, Theni and Tenkashi on red warning; Kanyakumari, Tirunelveli, Virudhunagar and Madurai on orange alert.
- Thursday, August 4: Dindigul, Tiruppur and Theni on orange alert.
Owing to the brewing tumultuous weather, the district administration in Tamil Nadu has decided to take all the necessary precautions ahead of time. Around four disaster response teams were deployed to Kanyakumari, Nilgiri, Tirunelveli and Coimbatore districts on Monday itself to respond to any emergencies in the areas.
However, the upcoming spell of rain is nothing new for Tamil Nadu and Puducherry this monsoon. Both regions have racked up splendid amounts of rainfall since June, resulting in a massive 88% rainfall excess (230 mm against the normal of 122 mm) during the first half of the season.
