Ivan Bears Down on Jamaica

By  | 

Hurricane Ivan continues to bear down on Jamaica, while Floridians look to sweating out a weekend of preparation.

Ivan is now centered about 85 miles southeast of Kingston, Jamaica, and about 660 miles southeast of Key West.

It's moving west-northwest at about 12 miles an hour, expected to bring its center to or near Jamaica Friday night or early Saturday morning.

There's a hurricane warning for Jamaica and the Cayman Islands. Ivan's top sustained winds are near 145 miles an hour, with fluctuation likely.

Forecasters say they're confident in what Ivan is going to do the next couple of days, but they're not sure what happens once it crosses Cuba. Some models show the system on a track similar to Hurricane Charley, going into southwest Florida and up the state.

But steering currents are expected to weaken, so other models show paths near or along the west coast of Florida. One model shows it going even farther west, going into the western Florida Panhandle next Tuesday sometime.

For now, the middle of the official forecast track shows Ivan's center going just offshore from the Tampa Bay area and coming ashore a little farther north.

Ivan centered at latitude 16.8 north, longitude 75.8 west.
