DISCUSSION AND 48-HOUR OUTLOOK
At 500 PM EDT (2100 UTC), the center of Tropical Storm Nate was
located near latitude 14.9 North, longitude 84.3 West. Nate is
moving toward the north-northwest near 10 mph (17 km/h) and this
motion is expected to continue during the next couple of days with a
significant increase in forward speed. On the forecast track, the
center of Nate should move across eastern Honduras this evening and
over the northwestern Caribbean Sea tonight and Friday. The center
is then expected to move near or over the northeastern part of the
Yucatan Peninsula and the adjacent islands late Friday or Friday
night, and move into the Gulf of Mexico on Saturday.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Strengthening is likely once the center moves over the northwestern
Caribbean Sea tonight and Friday, and Nate could be near hurricane
strength as the center approaches the Yucatan Peninsula.
Tropical-storm-force winds extend outward up to 50 miles (85 km)
mainly to the northeast of the center.
The estimated minimum central pressure is 1000 mb (29.53 inches).
HAZARDS AFFECTING LAND
RAINFALL: Nate is expected to produce the following rain
accumulations into Saturday:
Southern Honduras and western Nicaragua: 6 to 10 inches, max 20
Eastern El Salvador and northern Costa Rica: 3 to 6 inches, max 10
Northern Honduras/Nicaragua, eastern Yucatan/Belize and western
Cuba: 2 to 4 inches, max 8 inches
Central Honduras: 2 to 4 inches
Cayman Islands and Jamaica: 1 to 2 inches
Heavy rainfall will occur over a wide area, including locations well
away from the center along the Pacific coast of Central America.
Rainfall across all of these areas may produce life-threatening
flash floods and mudslides.
WIND: Tropical storm conditions are expected within portions of the
warning area in Nicaragua and Honduras tonight. Hurricane
conditions are possible within the hurricane watch area in Mexico
Friday night, with tropical storm conditions expected by late
STORM SURGE: A storm surge will raise water levels by as much as 1
to 3 feet above normal tide levels along the immediate coast near
and to the north of where the center of Nate makes landfall on the
Yucatan Peninsula and the adjacent islands. Near the coast, the
surge will be accompanied by large and destructive waves.
SURF: Swells generated by Nate are affecting portions of the coast
of Nicaragua, and will begin to affect other land areas around the
northwestern Caribbean during the next day or two. These swells are
likely to cause life-threatening surf and rip current conditions.
