DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Tropical Storm Julia was located near latitude 12.6 North, longitude 80.5 West. Julia is moving toward the west near 18 mph (30 km/h). A general westward motion with some decrease in forward speed is expected through Monday. On the forecast track, the center of Julia is expected to pass near or over San Andres and Providencia Islands later today and then move inland along the coast of Nicaragua early Sunday morning. Julia is then expected to cross Nicaragua on Sunday, and move near or along the Pacific coasts of Nicaragua, Honduras, and El Salvador Sunday night and Monday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Strengthening is forecast, and Julia is expected to become a hurricane later today. Weakening is forecast after the center moves inland over Nicaragua on Sunday, but Julia could still be at or near tropical storm strength when it moves near or along the Pacific coasts of Nicaragua, Honduras, and El Salvador Sunday night and Monday. Julia is forecast to become a remnant low by late Monday and dissipate by Tuesday. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. Data from a recent Air Force Reserve Hurricane Hunter mission indicate that the minimum central pressure is 993 mb (29.32 inches).

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 is likely to 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.
