For the Sister Islands
Winds are currently out of the northeast with speed of 40 to 50 mph with higher gusts, gradually increasing to hurricane strength around 8 p.m. as it veers to the south to southeast. We can expect wave heights up to 15 to 20 feet, with a storm surge of 2 to 4 feet near the coast. A maximum speed of 85 mph is forecast for the Sister Islands during these times. The center of the system is expected to pass within 12 miles southwest of the sister Islands.
Winds will shift to the southeast from around 7 p.m., and gradually decrease to below tropical storm force strength by 6 a.m. on Saturday morning.
For Grand Cayman
Tropical storm force winds of around 40 mph from the north and northwest will begin to affect Grand Cayman from around 5 to 7 p.m. tonight; gradually increasing to near 55 mph by midnight tonight. Wave heights of up to 16 – 18 feet can be expected on the north, west and southern coasts of Grand Cayman, with a storm surge of 1 to 3 feet near the coast. Winds will gradually move through the west & southwest from 2 a.m. falling below Tropical storm force by 8:00 a.m. on Saturday morning.
Rain-bands associated with Gustav have already begun to affect the Cayman Islands. Weather models are forecasting around 3-5 inches of rainfall with the passage of Hurricane Gustav, therefore flooding of low lying areas is expected and all residents in such areas should have taken necessary precautions.
All marine interests should remain in safe Harbour.
All residents should now be and remain indoors and should continue to closely monitor the progress of Gustav.
