DISTURBANCE BECOMES A TROPICAL DEPRESSION NEAR THE ABC ISLANDS AND THE COAST OF NORTHWESTERN VENEZUELA…HEAVY RAINS EXPECTED ACROSS THE ABC ISLANDS AND PORTIONS OF NORTHERN SOUTH AMERICA THROUGH FRIDAY
NHC Advisory number 3
The depression is moving toward the west near 15 mph (24 km/h), and a generally westward motion is expected to continue through Sunday.
On the forecast track, the cyclone is expected to move near the ABC Islands, the coast of northwestern Venezuela, and the Guajira Peninsula of Colombia tonight through Friday morning.
The system is then forecast to move across the southwestern Caribbean Sea, moving near San Andres and Providencia Islands Saturday night, and
approaching the coast of Nicaragua on Sunday morning.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Gradual strengthening is expected for the next 12-24 hours, and the
depression is expected to become a tropical storm by Friday morning.
After that, a faster rate of strengthening is likely, with the system expected to become a hurricane by Saturday night as it approaches San Andres and Providencia Islands.
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are possible on the Colombian islands of
San Andres, Providencia, and Santa Catalina Saturday night, with
tropical storm conditions possible by Saturday afternoon.
Tropical storm conditions are expected along the coast of Colombia
within the warning area by early Friday. Gusts to tropical
storm force are also possible across the ABC Islands and the
northwestern coast of Venezuela tonight.
RAINFALL: The tropical depression is expected to produce the following rain accumulations through early Monday:
Northern Coastal Venezuela…3 to 6 inches, isolated 10 inches.
Aruba, Bonaire, and Curacao…3 to 6 inches
Guajira Peninsula…3 to 6 inches, isolated 10 inches.
San Andres and Providencia…6 to 12 inches
Eastern Nicaragua…6 to 10 inches, isolated 16 inches.
Central Nicaragua…3 to 6 inches, isolated 10 inches.
Southwest Costa Rica and Southwestern Panama…4 to 8 inches, isolated 12 inches
This rainfall may cause life-threatening flash floods. There is also the potential for life-threatening mudslides across portions of Central America this weekend.
STORM SURGE: A storm surge could raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds on San Andres, Providencia, and Santa Catalina Islands. Near the coast, the surge will be accompanied by large and damaging waves.
SURF: Swells generated by the cyclone will affect the ABC Islands and portions of the coasts of northwestern Venezuela and the Guajira Peninsula of Colombia through Friday. Swells could reach Jamaica,
Providencia, and San Andres on Saturday, and portions of the coast of Central America on Sunday. These swells are likely to cause life-threatening surf and rip current conditions.
