North-East monsoon commenced over the South Peninsula with a delay of around four days. Despite the onset, Northeast monsoon remained weak. Northeasterly winds over the Bay of Bengal were obstructed by Cyclone Hamoon. Now, the cyclone has dissipated and northeasterly winds have strengthened.
Rain activities will now commence over the South Peninsula and the northeast monsoon will also become active. Until now Kerala had been receiving a few good spells of rain and isolated rain was reported over Tamil Nadu. But now, rain activities will intensify over Kerala, Tamil Nadu, Andhra Pradesh, and parts of Karnataka until October 31st.
Rain activities may subside a little bit November 1 onward, but scattered rain may continue over Kerala and Tamil Nadu. Another surge of Northeast monsoon will be between November 3rd and 6th. Although we do not expect heavy to very heavy downpours over Tamil Nadu and Andhra Pradesh. But the weather will not be completely dry and scattered rain will continue.
