DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 PM EST (0000 UTC), the center of Hurricane Otto was located near latitude 11.2 North, longitude 81.8 West. Otto is moving toward the west near 8 mph (13 km/h). This general motion is expected for the next couple of days with an increase in speed on Thursday. On the forecast track, the center of Otto will move onshore within the hurricane warning area on Thursday, and reach the Pacific coast of southern Nicaragua or northern Costa Rica early Friday. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that sustained winds have increased to 75 mph (120 km/h) with higher gusts. Additional strengthening is expected before landfall before weakening occurs over Central America after landfall. Hurricane force winds extend outward up to 10 miles (15 km) from the center, while tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The minimum central pressure estimated from Hurricane Hunter aircraft data is 984 mb (29.06 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 Thursday. These rains will likely result in life-threatening flash floods and mud slides. Outer rain bands from Otto are expected to produce rainfall accumulations of 4 to 8 inches over San Andres and Providencia islands, and the higher terrain of central and western Panama and southern Costa Rica through today. WIND: Hurricane conditions are expected within the hurricane warning area on Thursday, with tropical storm conditions expected to begin late tonight or Thursday morning, making outside preparations difficult or dangerous. Hurricane conditions are possible in the hurricane watch area on Thursday. Tropical storm conditions are expected on San Andres this evening. Tropical storm conditions are expected within the warning area on the Caribbean coast of Nicaragua tonight and Thursday. Tropical storm conditions are expected in the warning area along the Pacific coasts of Costa Rica and Nicaragua by Thursday night. STORM SURGE: The combination of a dangerous storm surge and large and destructive waves could raise water levels by as much 2 to 4 feet above normal tide levels in areas of onshore flow within the hurricane warning area. 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.
