HURRICANE CONDITIONS EXPECTED ON THE COAST OF NICARAGUA OVERNIGHT…LIFE-THREATENING FLASH FLOODS AND MUDSLIDES POSSIBLE FROM HEAVY RAINS OVER CENTRAL AMERICA AND SOUTHERN MEXICO THROUGH EARLY NEXT WEEK

NHC Advisory number 10

Julia is moving toward the west near 17 mph (28 km/h). A continued westward motion with some decrease in forward speed is expected during the next couple of days. On the forecast track, the center of Julia is expected to reach the coast of Nicaragua overnight, move across Nicaragua on Sunday, and then move near or along the Pacific coasts of Honduras, El Salvador, and Guatemala through Monday.

Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some additional strengthening is forecast this evening and tonight, and Julia could become a hurricane while passing near San Andres and Providencia Islands this evening. Julia is also expected to be a hurricane when it reaches the coast of Nicaragua overnight.

Weakening is expected once Julia moves inland, but it is forecast to still be a tropical storm when it moves off the Pacific coast of Nicaragua late Sunday. Julia should weaken to a tropical depression on Monday and dissipate by Monday night.

Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center.
