DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the center of Hurricane Julia was located inland over Nicaragua near latitude 12.4 North, longitude 84.6 West. Julia is moving toward the west near 16 mph (26 km/h). This general motion is expected to continue through tonight, followed by a slight turn to the west-northwest on Monday. On the forecast track, the center of Julia is expected to continue moving across Nicaragua today and emerge over the eastern Pacific by tonight. Julia is then forecast to move near or along the Pacific coasts of Honduras, El Salvador, and Guatemala on Monday and Monday night. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Additional weakening is expected today as Julia moves over Nicaragua, but it is still forecast to be a tropical storm when it emerges off the Pacific coast of Nicaragua by tonight. Julia is forecast to weaken to a tropical depression on Monday night and dissipate by Tuesday. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). The Bluefields International Airport in Nicaragua reported a sustained wind of 81 mph (130 km/h) a few hours ago a little after Julia had made landfall. The estimated minimum central pressure is 989 mb (29.20 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 and on the web at hurricanes.gov/text/MIATCDAT3.shtml. WIND: Hurricane conditions will continue near Julia's center and along the coast of Nicaragua within the warning area this morning. Hurricane conditions are possible along the coast of Nicaragua within the hurricane watch area this morning. Tropical storm conditions will continue along the Caribbean coast of Nicaragua within the tropical storm warning areas through this morning. Tropical storm conditions are possible along the coast of Honduras within the watch area through this morning. Tropical storm conditions are expected along the Pacific coasts of Nicaragua, Honduras, and El Salvador within the warning area beginning this afternoon into tonight. Tropical storm conditions are possible along the Pacific coast of Guatemala within the watch area on Monday. RAINFALL: Julia is expected to produce the following rainfall accumulations through early Tuesday: Nicaragua and El Salvador...5 to 10 inches, isolated 15 inches. Honduras, Belize, northern Guatemala, and the Isthmus of Tehuantepec in Mexico...3 to 6 inches, isolated 10 inches. San Andres, Providencia, and Panama...an additional 2 to 4 inches, isolated 12 inch storm total amounts. Southern Guatemala and Costa Rica...4 to 8 inches, isolated 12 inches. This rainfall may cause life-threatening flash floods and mudslides across Central America today and Monday. Flash flooding is anticipated across the Isthmus of Tehuantepec in Mexico early this week. STORM SURGE: A dangerous storm surge is likely still occurring along the coast of Nicaragua in areas of onshore winds, but water levels should subside today. Large and damaging waves will likely accompany the storm surge near the coast. SURF: Swells generated by Julia are affecting Jamaica, Providencia, and San Andres, and the coast of Central America. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
