Northeast Monsoon has been fairly active over the South Peninsula for the last couple of days. South Coastal Andhra Pradesh (CAP), Tamil Nadu, and Kerala have witnessed heavy downpours in some pockets. Moderate showers were widespread over most other parts of these sub-divisions. Active monsoon conditions are likely to prevail for another 48 hours and slow down later.
Kavali in CAP recorded first 3-digit rainfall of this season and measured 101mm in 24 hours, ending at 8.30a.m today morning. Parangipettai, in coastal Tamil Nadu, had a repeat of 14 Nov and recorded yet another 3 digit rainfall of 129mm in 24 hours. Karaikal missed the century mark and measured 93mm of rainfall. Nungambakkam, the record observatory for Chennai added another 51mm splash, taking the monthly total to 335.7mm, very close to the normal of 373.6mm. Coonoor and Valparai in Kerala also observed decent showers and recorded 77mm and 58mm rainfall, respectively. Adequate showers of varying spread and intensity were observed over many pockets of these three sub divisions.
An easterly wave travelling across coastal Tamil Nadu and coupled with cyclonic circulation over Comorin and Lakshadweep area has resulted in active northeast monsoon conditions for the last 2-3 days. More rains are likely for the next 24 hours and a marginal drop in the subsequent 24 hours. Thereafter, the activity is likely to slow down, as the systems move westward away from the landmass. However, the streaming northeasterly winds will keep thronging the south CAP and North Coastal Tamil Nadu for another 2 days. Accordingly, rain and thundershowers will continue over these parts on 24th and 25th November, as well.
