A low pressure in the Bay of Bengal will spin near Sri Lanka and southeastern India this week, bringing rounds of heavy rain to the island.
AccuWeather.com meteorologist have been monitoring this storm's development over the past few days. There is still a low chance that this system could develop into an organized tropical cyclone.
However, even without strengthening this storm will bring heavy rains for Sri Lanka through Thursday. The nearly unmoving storm will bring round after round of rain, leading to significant rainfall.
As much as 200 mm (8 inches) of rain could fall, especially along the eastern side of the island. A few isolated areas could see as much as 300 mm (12 inches) of rain through the end of the week.
Southeastern India could see some of this rain also. However, with the storm staying rather stationary much of the rain will stay over Sri Lanka.
All this rain concentrated over Sri Lanka brings the threat for flooding across the country. Heavy rains can lead to overflowing rivers and streams, water running over roadways, and mudslides.
Early in November, the remnants of tropical depression Wilma reorganized into a new depression and moved close to this area, passing over southern India and dumping 50-100 mm (2-4 inches) of rain on Sri Lanka and southern India.
However, the strongest system of the season so far was Phailin which stayed far away from Sri Lanka, instead affecting Andhra Pradesh and Orissa in northern India.
