The cyclonic storm ‘Burevi’ was parked over South-West Bay of Bengal 240 km away from Trincomalee (Sri Lanka), 470 km away from Pamban (India) to the East-South-East direction, and 650 km to the East-North-East of Kanniyakumari (India) at 5.30 am Wednesday morning, an India Meteorological Department (IMD) update said.
‘Burevi’ is expected to intensify (but below severe cyclone strength) through the course of Wednesday and move to the West-North-West to cross the Sri Lanka coast around close to North of Trincomalee in the evening/night, as a cyclone with a wind speed of 80-90 km/hr gusting to 100 km/hr (just below severe cyclone strength of 89-117 km/hr).
Cyclone status for three days
Burevi is expected to retain the cyclone status post-landfall, and emerge into Gulf of Mannar and adjoining Comorin area on Thursday morning. The cyclone, with wind speeds of 70-80 km/hr gusting to 90 km/hr, would be centered very close to Pamban (South-East Tamil Nadu) around noon, but may later bend its track to West-South-West to cross the South Tamil Nadu coast between Kanniyakumari and Pamban on Friday morning for a second landfall– as a cyclone with wind speeds of 70-80 gusting to 90 km/hr.
This would mean that ‘Burevi’ will remain a cyclone for three days, with proximity to land to its either side (the island of Sri Lanka and Peninsular India) alone, preventing it from intensifying further. Earlier last week, very severe cyclone ‘Nivar’ had crossed the North Tamil Nadu coast near Puducherry.
Sri Lankan agency forecast
The Sri Lankan Meteorological Department said that Burevi will cross the island’s East Coast between Batticaloa and Point-Pedro, close to Trincomalee on Wednesday evening/night, with wind speeds of 75-85 km/hr gusting up to 95 km/hr and later emerge into the Gulf of Mannar.
Intermittent showers/thundershowers will occur in the Eastern, Northern, Northern-Central, North-Western, Central, and Sabaragamuwa provinces. Very heavy rainfall above 20 cm can be expected at some places. Showers or thundershowers at times will occur elsewhere. Heavy rainfall above 10 cm can be expected at some other places. Very strong gusty winds (80-90 km/hr) can be expected in these provinces.
