DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Tropical Storm Delta was located near latitude 16.1 North, longitude 79.2 West. Delta is moving toward the west near 7 mph (11 km/h), and a turn toward the west-northwest is forecast later today. A faster northwestward motion is expected on Tuesday and Wednesday. On the forecast track, the center of Delta is expected to move away from Jamaica later today, move near or over the Cayman Islands early Tuesday, and approach western Cuba and the Yucatan Channel Tuesday afternoon or evening. Delta is forecast to move into the southeastern Gulf of Mexico Tuesday night, and be over the south-central Gulf of Mexico on Wednesday. Maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Additional strengthening is expected during the next few days, and Delta is expected to become a hurricane tonight or Tuesday before it nears western Cuba. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Delta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. STORM SURGE: A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels along the south coast of western Cuba near and to right of where the center makes landfall. Near the coast, the surge will be accompanied by large and dangerous waves. WIND: Tropical storm conditions are expected in the Cayman Islands beginning late today or tonight. Hurricane conditions are expected within the Hurricane Warning area in western Cuba by late Tuesday afternoon, with tropical storm conditions expected by Tuesday morning. Hurricane conditions are possible on the Isle of Youth beginning Tuesday afternoon with tropical storm conditions expected by early Tuesday. Tropical storm conditions are possible in the Tropical Storm Watch area in Cuba on Tuesday. RAINFALL: Through midweek, Delta is expected to produce 4 to 6 inches of rain with isolated maximum totals of 8 inches across Jamaica, the Cayman Islands and western Cuba. This rainfall could lead to significant flash floods and mudslides.
