DISCUSSION AND OUTLOOK ---------------------- At 800 PM EDT (0000 UTC), the center of Tropical Storm Julia was located near latitude 12.8 North, longitude 75.2 West. Julia is moving toward the west near 18 mph (30 km/h). A westward motion with some decrease in forward speed is expected through Sunday night. On the forecast track, the center of Julia is expected to pass near or over San Andres and Providencia Islands Saturday evening and then reach the coast of Nicaragua Sunday morning. Julia or its remnants will then turn west-northwestward over Central America by Monday. Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are now near 45 mph (70 km/h) with higher gusts. Additional strengthening is forecast while Julia moves across the southwestern Caribbean Sea during the next day or two, and the system is expected to become a hurricane by the time it passes near or over San Andres and Providencia Islands and reaches the coast of Nicaragua. Quick weakening is anticipated after Julia moves inland on Sunday, and it is likely to become a remnant low or dissipate by Monday. Tropical-storm-force winds extend outward up to 80 miles (130 km) mainly to the northeast of the center. The estimated minimum central pressure from the Hurricane Hunter aircraft data is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Julia can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Hurricane conditions are expected on the Colombian islands of San Andres, Providencia, and Santa Catalina by Saturday evening, with tropical storm conditions beginning by Saturday afternoon. Hurricane conditions are expected along the coast of Nicaragua within the hurricane warning area Sunday morning, with tropical storm conditions beginning by Saturday night. Hurricane conditions are possible along the coast of Nicaragua within the hurricane watch areas Sunday morning. Tropical storm conditions are expected along the coast of Nicaragua within the tropical storm warning areas by Saturday night or early Sunday. Tropical storm conditions are possible along the coast of Honduras within the watch area on Sunday. RAINFALL: Julia is expected to produce the following rainfall accumulations through early Monday: San Andres and Providencia...6 to 12 inches. Eastern Nicaragua...5 to 10 inches, isolated 15 inches. The rest of Nicaragua, southern Honduras, eastern El Salvador... 4 to 8 inches, isolated 12 inches. Pacific basins of Costa Rica and western Panama...3 to 6 inches, isolated 10 inches. Northern Honduras, southern Belize, central Guatemala...4 to 7 inches, isolated 12 inches. This rainfall may cause life-threatening flash floods and mudslides through this weekend. STORM SURGE: A storm surge is likely to raise water levels by as much as 2 to 4 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. A storm surge could raise water levels by as much as 4 to 6 feet above normal tide levels along the immediate coast of Nicaragua in areas of onshore winds. Large and damaging waves will likely accompany the storm surge near the coast. SURF: Swells generated by Julia are expected to reach Jamaica tonight, Providencia and San Andres Islands on Saturday, and portions of the coast of Central America late Saturday into Sunday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
