DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Tropical Storm Erika was located near latitude 19.1 North, longitude 75.1 West. Erika is moving toward the west-northwest near 20 mph (31 km/h), and this general motion is expected to continue through tonight. A turn toward the northwest and a decrease in forward speed are expected on Sunday. On the forecast track the center of Erika will move near over portions of eastern Cuba later today and move across central Cuba tonight. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Erika is expected to weaken to a tropical depression today as it moves over land. It is also possible that Erika could degenerate into a trough of low pressure today while it moves over the high terrain of eastern Cuba. An Air Force Reserve Hurricane Hunter aircraft will be investigating Erika later this morning. Tropical storm force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Erika is expected to produce total rainfall accumulations of 3 to 6 inches with maximum amounts of 10 inches possible across portions of the Dominican Republic, Haiti and eastern Cuba through Sunday. These rains could cause life-threatening flash floods and mud slides. In addition, the outer bands of Erika are also expected to produce rainfall amounts of 1 to 3 inches across the Turks and Caicos Islands as well as the southeastern and central Bahamas through Sunday. WIND: Tropical storm conditions across Haiti will gradually subside this morning, and will continue in portions of the Turks and Caicos Islands and the southeastern Bahamas for the next few hours. Tropical storm conditions are possible over eastern Cuba today. NEXT ADVISORY ------------- Next intermediate advisory at 800 AM EDT. Next complete advisory at 1100 AM EDT. $$ Forecaster Brennan |
