DISCUSSION AND OUTLOOK ---------------------- At 300 PM CST (2100 UTC), the center of Tropical Storm Eta was located by satellite and Cuban radar data near latitude 23.2 North, longitude 85.1 West. Eta is moving toward the north near 7 mph (11 km/h). A motion toward the north or north-northeast is forecast through Wednesday night, followed by a turn toward the northeast on Thursday. On the forecast track the center of Eta will move parallel to but offshore of the Florida west coast on Thursday and move near or over Apalachee Bay Thursday night and Friday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some strengthening is forecast through Thursday morning, and Eta could be near hurricane strength by Wednesday night or Thursday morning. Gradual weakening is expected to begin Thursday afternoon or evening. Satellite-derived wind data indicate that tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 992 mb (29.30 inches).

Eta is expected to produce the following rainfall amounts through Thursday: Portions of West Florida and the Sun Coast, including the Tampa Bay area: 1 to 2 inches, with isolated totals of 4 inches. Flash and river flooding will be possible in western Cuba, along with landslides in areas of higher terrain. Additional flash and urban flooding will be possible in South Florida, especially across previously inundated areas, and eventually along portions of West Florida and the Sun Coast.
