ECONOMYNEXT – Sri Lanka has been warned of a tropical weather system that will intensify into deep depression on November 7 and move parallel to the island’s eastern coast, bringing heavy rains and somewhat strong winds.
Shortly before midnight on November 7, the system was in the Bay of Bengal, about 490 kilometres east-southwest of Pottuvil, Sri Lanka and 640 South East of Trincomalee and moving at a speed of 15 kilometres an hour, the Indian Meteorological Office said in tropical weather outlook for the Indian Ocean region.
“It is very likely to intensify further into a deep depression during next 12 hours,” the advisory said.
“It is very likely to move west-northwestwards initially across southwest Bay of Bengal during next 36 hours.”
“Thus, Equatorial waves are likely to support enhanced convective activity in association with the low pressure area over the region till 8th January. Thereafter, slight weakening of these features is indicated.
“There is good consensus among various models with respect to west-northwestwards movement of the system across southwest Bay of Bengal during next 3 days.
“However, The 07th/00 UTC run ECMWF model is indicating the initial west northwestwards movement till 9th/00 UTC and thereafter it is indicating north-northwestward movement over southwest Bay of Bengal parallel to Sri Lanka coast till 10th/00 UTC.”
Sri Lanka’s met department is warning of winds around 50 to 60 kilometres and rains of 100 millimetres to the Northern, Eastern, North Central, Uva, Central Provinces in particular as as well as some other parts of the island on the November 08 and 09.
Sri Lanka has issued multiple landslide warnings. After Cyclone Ditwah many mountain slopes in Sri Lanka are already weakened.
Cyclone Ditwah left 820 people dead or missing, with bodies buried deep under mudslides which could not be recovered.
