TRACKING THE TROPICS
Tropical Storm Imelda has formed near Cuba and moving towards the Bahamas.
A Tropical Storm Warning is in effect for Central Bahamas
A Tropical Storm Watch is in effect for East coast of Florida including Flagler/Volusia County Line
A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, within 36 hours.
A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
The center of Tropical Storm Imelda was located by Air Force reconnaissance data near latitude 23.9 North, longitude 77.3 West.
Imelda is moving toward the north near 7 mph (11 km/h). A faster motion to the north is expected later today and continuing through Monday.
Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. The threshold for a tropical storms is 39 miles per hour. Strengthening is expected during the next few days, and Imelda is forecast to become a hurricane by late Monday or Tuesday.
Tropical-storm-force winds extend outward up to 30 miles (50 km) from the center. The minimum central pressure estimated by aircraft dropsonde data is 998 mb (29.47 inches).
HAZARDS AFFECTING LAND
Tropical storm conditions are occuring in the central Bahamas and are expected in the northwestern Bahamas later this afternoon. Tropical storm conditions are possible in the watch area along the east coast of Florida on Monday.
RAINFALL: Tropical Storm Imelda is expected to produce additional rainfall of 2 to 6 inches across eastern Cuba and 6 to 12 inches across the northwest Bahamas through Tuesday. This rainfall will likely produce flash and urban flooding. Mudslides are also possible in areas of higher terrain across eastern Cuba. Storm total rainfall amounts of 2 to 4 inches with local maxima of 7 inches are expected into Wednesday morning across portions of the coastal Carolinas.
STORM SURGE: A storm surge will raise water levels by as much as 1 to 3 feet above ground level along the immediate coast in areas of onshore winds in the northwestern Bahamas.
Near the coast, the surge will be accompanied by large waves.
Minor coastal flooding is possible in areas of onshore winds over the Southeastern U.S. coastline. The water could reach the following heights above ground somewhere in the indicated areas if the surge occurs over the next several high tide cycles...Volusia/Brevard County Line, Florida to the South Santee River, South Carolina...1 to 2 ft
SURF: Swells generated by Tropical Storm Imelda and Hurricane Humberto will affect portions of the Bahamas this weekend, and spread to much of the east coast of the U.S. early this week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
HURRICANE HUMBERTO
According to the National Hurricane Center the center of Hurricane Humberto was located near latitude 24.6 North, longitude 64.3 West. Humberto is moving toward the west-northwest near 13 mph (20 km/h). A gradual turn toward the northwest, and then north is expected over the next couple of days.
