Tropical Cyclone hitting Sri Lanka, South India


A tropical depression over the southwestern Bay of Bengal will gain tropical cyclone status as it makes its way west to the south coast of India.
Flooding rain and damaging winds will threaten parts of Sri Lanka and southeastern India along and near the path of this low.
Seas will be dangerous for fishing boats and other small vessels.

Weekly Hydro-meteorological Report, 01 November 2012


Highlights

Monitoring and Prediction
The tropical storm that started to the West of Sri Lanka propagated North-Westwards drenching the Northeastern seaboard in particular and the rest of the island considerably as well as it intensified to cyclonic speeds. This is an early start to the cyclone that usually lasts from November till February– there has only been one that has made landfall in Sri Lanka recorded during October for the past 140 years. The anomalously warm sea surfaces to the east of Sri Lanka is one of the factors that contributes to enhanced cyclogenesis. The forecasts for the next week are for continued wet weather but only reaching a weekly accumulation of about 75mm..

The drought during the Yala season abated at the start of September and now as is seasonable with the start of the Maha season, we have heavy rainfalls. For the same reasons that Yala was drought ridden (warm Central Indian Ocean and Pacific Ocean surface temperatures), Sri Lanka and the sea towards eastern Africa is likely to have a wetter and warmer period till December.
