2012-10-23 18:26:47 | (0 Comments)
The Met Service is reporting that the centre of Sandy is forecast to reach the southern coast of Jamaica near midday tomorrow.
This graph indicates that central and eastern parishes of Jamaica will get some of the strongest winds associated with Sandy - National Hurricane Center
The eye of the system is expected to first pass over land in the vicinity of Clarendon and St Catherine.
It will then move northward across the island, exiting the island by way of St Ann, heading towards eastern Cuba by Wednesday evening.
According to the Met Service, the hurricane warning remains in effect for the island.
This means that the following dangerous effects of a hurricane are expected to affect Jamaica in 36 hours or less:
· Dangerously high water or a combination of dangerously high water and exceptionally high waves, even though winds expected may be less than hurricane force.
· Average winds 64 knots (118 km/h) or higher.
At 4:00 p.m. the centre of Tropical Storm Sandy was located near Latitude 14.3 degrees North, Longitude 77.6 degrees West, or about 420 kilometres (260 miles) south-southwest of Kingston, Jamaica or 290 kilometres (180 miles) south of the Pedro Cays.
Sandy is moving towards the north-northeast near 9 km/h (6 mph) and this general motion is expected to continue at a faster forward speed today and tomorrow.
Maximum sustained winds remain near 85 km/h (50 mph), with higher gusts, and Sandy is expected to strengthen into a hurricane while approaching Jamaica tomorrow morning.
Tropical storm force winds extend outward up to 165 kilometres (105 miles), mainly east of the centre.
Rainfall, associated with Tropical Storm Sandy is forecast to increase this evening, tonight and tomorrow morning producing rainfall amounts in excess of 150 millimetres per day; hence, flash flooding is expected.
Hurricane-force winds will gradually develop during Wednesday morning and could generate storm surge of 1-2 metres (3-7 feet) along Jamaica’s southeastern coastline.
The Met Service say periods of heavy rainfall and gusty winds are likely to persist through Thursday.
It says all small craft operators including fishers from the cays and banks should by now have completed all the necessary safety precautions and are advised to remain in safe harbour until all warning messages have been lifted and wind and sea conditions have returned to normal.
The next Bulletin on Tropical Storm Sandy will be issued at 8:00 p.m. today.
