Friday, November 11: Parts of Tamil Nadu, including its capital city Chennai, have been placed on rough weather alerts for the next 48 hours, as the South Indian state braces for very heavy to extremely heavy rains.
The India Meteorological Department (IMD) has forecast fairly widespread to widespread rains, along with isolated heavy to very heavy showers (64.5 mm-204 mm) across Tamil Nadu from Friday to Sunday, November 11-13. Furthermore, isolated extremely heavy downpours (204 mm) are expected to drench north-coastal Tamil Nadu on Friday and north Tamil Nadu on Saturday.
Given these predictions, the IMD’s regional met centre based in Chennai has issued red warnings (meaning ‘take action’ to stay safe from extreme weather) over the districts of Thiruvallur, Ranipettai and Kancheepuram on Friday and Nilgiris, Dindigul and Theni on Saturday.
Moreover, the department has also placed orange alerts (meaning ‘be prepared’ for rough conditions) across Chennai, Vellore, Tiruppattar, Thiruvannamalai, Chengalpattu, Villupuram, Cuddalore, Ariyalur, Nagapattinam, Thanjavur, Thiruvarur and Karaikal on Friday.
Come Saturday, these 12 districts will be joined by Thiruvallur, Ranipettai, Kancheepuram, Vellore, Thiruvallur, Thiruvannamalai, Thiruppur and Coimbatore in being on orange alert.
Along with heavy to very heavy showers, Chennai city and its surrounding areas may also experience thunderstorms and lighting for the next 48 hours.
In view of these warnings, the Tamil Nadu school education department has declared a holiday for schools and colleges in Chennai, Tiruvallur, Kancheepuram, Chengalpattu, Vellore and Ranipet districts on Friday and Saturday.
Overall, these intense showers will be caused by a well-marked low-pressure area located over southwest Bay of Bengal and adjoining areas of northeast Sri Lanka, along with its associated cyclonic circulation. The low is very likely to move northwestwards (towards Tamil Nadu-Puducherry coasts) till Saturday, and then move west-northwestwards (across Tamil Nadu-Puducherry and Kerala) over the weekend.
Its presence in the sea will trigger squally weather with wind speeds reaching 40-45 kmph, gusting to 55 kmph, across the southern states — especially across the Tamil Nadu, Puducherry and Andhra coasts. The sea conditions will also be rough, which is why the fisherfolk have been advised against venturing into the waters during this forecast period.
