DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 PM EST (2100 UTC), the center of Hurricane Otto was located inland over southern Nicaragua near latitude 11.0 North, longitude 84.3 West. Otto is moving toward the west near 12 mph (19 km/h), but a faster motion toward the west or west-southwest is expected to begin tonight and continue through early Saturday. On the forecast track, the center of Otto will continue to move across southern Nicaragua and northern Costa Rica through this evening, and emerge off of the Pacific coast of southern Nicaragua or northern Costa Rica by early Friday. Maximum sustained winds have decreased to near 100 mph (155 km/h) with higher gusts. Rapid weakening is forecast and Otto is expected to become a tropical storm by tonight. Additional weakening is anticipated after Otto moves over the Pacific Ocean. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The estimated minimum central pressure is 979 mb (28.91 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Total rainfall of 6 to 12 inches, with isolated amounts of 15 to 20 inches, can be expected across northern Costa Rica and southern Nicaragua through tonight. These rains will likely result in life-threatening flash floods and mudslides. Recent reports from amateur radio operators indicate that mudslides are occurring over portions of northern Costa Rica. Outer rain bands from Otto are expected to produce rainfall accumulations of 3 to 6 inches with total rainfall amounts of up to 10 inches over the higher terrain of far western Panama and southern Costa Rica through Friday. Additional rainfall amounts of 1 to 3 inches can be expected tonight over San Andres and Providencia Islands. WIND: Hurricane and tropical storm conditions are occurring in the warning area. Tropical storm conditions are expected in the warning area along the Pacific coasts of Costa Rica and Nicaragua by this evening. STORM SURGE: The combination of a dangerous storm surge and large and destructive waves could raise water levels by as much 3 to 5 feet above normal tide levels in areas of onshore flow within the hurricane warning area. Water levels will subside by tonight. SURF: Swells generated by Otto are likely to cause life-threatening surf and rip current conditions over the next several days along the coasts of Panama, Costa Rica, and Nicaragua.
