Discussion and outlook
At 1000 AM CDT (1500 UTC), the center of Subtropical Storm Alberto was located near latitude 19.7 North, longitude 86.8 West. The storm is moving toward the north-northeast near 6 mph (9 km/h). A general slow motion toward the north is expected through the weekend, followed by a northwest turn by Monday.
On the foreast track, Alberto is expected to pass near the eastern coast of the Yucatan peninsula on Friday, be near the western tip of Cuba Saturday morning, emerge over the southeastern Gulf of Mexico by Saturday night, and approach the north-central Gulf Coast on Monday.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual strengthening is forecast for the next 72 hours.
Winds of 40 mph extend outward up to 115 miles (185 km) from the center.
The estimated minimum central pressure is 1005 mb (29.68 inches).
Hazards affecting land
RAINFALL: Alberto is expected to produce total rain accumulations of 10 to 15 inches with isolated totals of 25 inches across the northeastern portions of the Yucatan Peninsula and western Cuba.
These rains could produce life-threatening flash floods and mudslides. Rainfall accmumulations of 4 to 8 inches with maximum amounts of 12 inches are possible across the Florida Keys and southern and southwestern Florida. Heavy rain will likely begin to affect the central Gulf Coast region and the southeastern Untied States later this weekend and continue into early next week.
Flooding potential will increase across this region early next week as Alberto is forecast to slow down after it moves inland.
WIND: Tropical storm conditions are possible within the watch area through Saturday.
SURF: Swells generated by Alberto are affecting portions of the coast of eastern Yucatan Peninsula and western Cuba. These swells are likely to cause life-threatening surf and rip current conditions. Hazardous surf conditions are likely to develop along much of the central and eastern U.S. Gulf Coast this weekend. For more information, consult products from your local weather office.
The next advisory will be issued at 4:00 pm Friday.
