WIND: Tropical storm conditions are likely occuring along the Pacific coast of northwestern Nicaragua and should spread to the Pacific coasts of Honduras and El Salvador overnight. Tropical storm conditions are possible along the Pacific coast of Guatemala on Monday. RAINFALL: Julia is expected to produce the following rainfall accumulations through 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. Southern Guatemala...4 to 8 inches, isolated 12 inches. This rainfall may cause life-threatening flash floods and mudslides across Central America into Monday. Flash flooding is anticipated across the Isthmus of Tehuantepec in Mexico early this week. SURF: Swells generated by Julia continue to affect Providencia and San Andres Islands and the Caribbean coast of Central America, but should gradually subside through Monday night. Swells not caused by Julia are expected to affect the Pacific coast of Central America during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
