DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the center of Tropical Depression Thirteen was located near latitude 12.3 North, longitude 71.9 West. 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 over the southwestern Caribbean Sea today through Saturday. The system is forecast to pass near San Andres and Providencia Islands Saturday night, and approach the coast of Nicaragua on Sunday morning. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Gradual strengthening is forecast today, and the depression is expected to become a tropical storm later this morning or this afternoon. A faster rate of strengthening is forecast on Saturday and Saturday night, and the system is expected to become a hurricane before it reaches San Andres and Providencia Islands and the coast of Nicaragua this weekend. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Depression Thirteen can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Hurricane conditions are possible on the Colombian islands of San Andres, Providencia, and Santa Catalina Saturday night into early Sunday, with tropical storm conditions possible by Saturday afternoon. Tropical storm conditions are expected along the coast of Colombia within the warning area this morning. Gusts to tropical storm force are possible across portions of the northwestern coast of Venezuela during the next several hours. RAINFALL: The tropical depression is expected to produce the following rain accumulations through early Monday: Northern Venezuela, Aruba, Bonaire, and Curacao...additional 1 to 3 inches Guajira Peninsula...3 to 6 inches, isolated 10 inches. San Andres and Providencia...6 to 12 inches Portions of Central America...5 to 10 inches, isolated 15 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 are affecting the ABC Islands and portions of the coasts of northwestern Venezuela and the Guajira Peninsula of Colombia. These swells are forecast to spread westward and reach Jamaica late tonight, Providencia and San Andres Islands on Saturday, and portions of the coast of Central America on Saturday night and Sunday.
