At 800 AM EDT (1200 UTC), the center of Tropical Storm Ian was located near latitude 14.2 North, longitude 74.5 West. Ian is moving toward the west-southwest near 15 mph (24 km/h). A westward to west-northwestward motion is expected through early Sunday. A turntoward the northwest is forecast late Sunday, followed by a north-northwestward turn by late Monday. On the forecast track, the center of Ian is forecast to move across the central Caribbean Sea today, pass southwest of Jamaica on Sunday, and pass near or over the Cayman Islands Sunday night and early Monday. Ian will then approach western Cuba on Monday.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Strengthening is forecast during the next few days, and Ian is expected to become a hurricane late Sunday or Sunday night.

Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center.

HAZARDS AFFECTING LAND
----------------------

WIND: Hurricane conditions are possible in the Cayman Islands by early Monday, with tropical storm conditions possible by Sunday night. Tropical storm conditions are possible in Jamaica on Sunday.

RAINFALL: Ian is expected to produce the following rainfall:

Southern Haiti and Southern Dominican Republic: 2 to 4 inches, with local maximum up to 6 inches
Jamaica and the Cayman Islands: 4 to 8 inches, with local maximum up to 12 inches
Western to central Cuba: 6 to 10 inches, with local maximum up to 14 inches
These rains may produce flash flooding and mudslides in areas of higher terrain, particularly over Jamaica and Cuba.
Florida Keys and South Florida: Heavy rains could begin as early as Monday. Limited flash and urban flooding is possible with this
rainfall.

STORM SURGE: Storm surge could raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds in the Cayman Islands Sunday night into Monday. Localized coastal flooding is possible along the coast of Jamaica in areas of onshore winds on Sunday.

SURF: Swells generated by Ian will begin affecting Jamaica, the Cayman Islands, and Cuba over the next several days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
