Weathermen are now focused on the track of the remnant of erstwhile typhoon Damrey that is heading into the Gulf of Thailand and onward into the Andaman Sea.
The Thailand Met Department located the incoming remnant, which is a depression now, to 150 km north-east of Phnom Penh, Vietnam, as it continued to travel west-southwest.
'Damrey' hit the Vietnam coast yesterday morning, and has weakened into a depression today. It is expected to weaken into a low-pressure area in the Gulf.
INCOMING 'THAI LOW'
India Met Department (IMD) expects the 'low' to enter the South Andaman Sea day after tomorrow (Tuesday) and is widely thought to be what is needed to boost the ongoing North-East monsoon.
The Andaman Sea has already set out a trough to receive the incoming 'low' from the Gulf; another trough waits over the South-West Bay of Bengal off Tamil Nadu-South Coastal Andhra Pradesh.
Yet another trough is lurking over the Lakshadweep area and its neighbourhood. All these in tandem would help the North-East monsoon flows to sustain themselves into early this week.
The US Climate Prediction Centre sees excess rainfall for the southern tip of peninsular India during the week ending November 10, while the rest of Tamil Nadu and Kerala may receive normal rain.
During the week that follows (November 11 to 17), it sees most of the rain activity to be concentrated over the Odisha and Bengal coasts.
MOST CLOUD COVER IN SOUTH
As for today, the IMD has forecast heavy rain at isolated places over Tamil Nadu and Puducherry. Thunderstorms accompanied by lightning are likely at isolated places over Tamil Nadu, Puducherry, Kerala, South Coastal Andhra Pradesh and Rayalaseema.
Today's satellite pictures shows the cloud cover extending from the north of Chennai all the way along the Andhra Prades coast to Visakhapatnam-Srikakulam.
The heavier clouds are located over South Tamil Nadu and Kerala and cover the Kanya Kumari-Nagercoil-Thiruvananthapuram-Tirunelveli-Tenkasi-Kayathar-Thoothukudi belt.
This is attributed to the confluence of flows generated by the troughs over the South-West and adjoining West-Central Bay of Bengal and over the Lakshadweep region.
In the outlook for tomorrow, the IMD said heavy rain would spread out from Tamil Nadu and Puducherry to South Coastal Andhra Pradesh and Kerala.
