At long last, the hyperactive trough in South-West Bay of Bengal has given birth to a low-pressure area. But the excess rainfall belt is moving from Chennai to the southern districts and adjoining Kerala.
Under the influence of the ‘low,’ the North-East monsoon has been ‘vigorous’ over Kerala and active over Tamil Nadu, an update from Regional Met Centre, Chennai, said.
Vigorous monsoonRainfall occurred at many places over Tamil Nadu and Kerala and at a few places over Rayalaseema and south interior Karnataka during the 24 hours ending on Thursday morning.
Isolated rainfall was reported from coastal Andhra Pradesh, north interior and coastal Karnataka.
The chief amounts of rainfall (recorded in cm) during the 24 hours ending on Thursday morning are: Cuddalore-13; Srivilliputhur-12; Peraiyur- 11; Valangaiman-9; Panruti-8; Puducherry, Mudukulatur, Cheranmahadevi and Kadaladi-7 each. The forecast for the next three to four days indicated that the excess rainfall belt is leaving Chennai to the South, adjoining Kerala and Lakshadweep.
