DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 AM EST (1200 UTC), the eye of Hurricane Otto was located by a reconnaissance plane near latitude 11.0 North, longitude 82.9 West. Otto is moving toward the west near 8 mph (13 km/h), and this motion is expected to continue today. A faster motion toward the west or west-southwest is forecast to begin tonight and continue through early Saturday. On this track, the center of Otto will make landfall within the hurricane warning area today, and move across southern Nicaragua and northern Costa Rica through this evening. The center of Otto is expected to reach the Pacific coast of southern Nicaragua or northern Costa Rica tonight. Data from a reconnaissance plane indicate that the maximum sustained winds have increased to near near 105 mph (165 km/h) with higher gusts. Some additional strengthening is possible before landfall. Weakening is expected after landfall, and Otto is forecast to weaken to a tropical storm by tonight. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The minimum central pressure just reported by an Air Force Reserve reconnaissance plane was 976 mb (28.82 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 today. These rains will likely result in life-threatening flash floods and mudslides. 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 this morning. WIND: Hurricane conditions are expected to reach the hurricane warning area late this morning or early this afternoon, with tropical storm conditions expected to begin shortly. Hurricane conditions are possible in the hurricane watch area today. Tropical storm conditions are expected within the warning area on the Caribbean coast of Nicaragua today. 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 4 to 6 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.
