DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1000 AM EST (1500 UTC), the eye of Hurricane Otto was located
near latitude 11.0 North, longitude 83.4 West. Otto is moving toward
the west near 9 mph (15 km/h), but 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 during the next several hours, and
then 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 or early
Friday.
Otto is a dangerous hurricane with maximum sustained winds near
110 mph (175 km/h) and higher gusts. Some additional strengthening
is possible during the next several hours before landfall. Weakening
is expected after landfall, and Otto is forecast to become a
tropical storm by tonight and additional weakening is anticipated
thereafter.
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 975 mb (28.80 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 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 today
over San Andres and Providencia Islands.
WIND: Hurricane conditions are expected to reach the hurricane
warning area during the next several hours, while tropical storm
conditions are likely to be occuring already. Hurricane conditions
are possible in the hurricane watch area today.
Tropical storm conditions are likely occurring within the warning
area on the Caribbean coast of Nicaragua. 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. Please consult
products from your local weather office.
