DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 100 AM EST (0600 UTC), the center of Hurricane Otto was located
near latitude 11.2 North, longitude 82.4 West. Otto is moving toward
the west near 9 mph (15 km/h), and this general motion is forecast
to continue for the next couple of days with an increase in forward
speed expected later today. On the forecast track, the center of
Otto will move onshore within the hurricane warning area later
today, and reach the Pacific coast of southern Nicaragua or northern
Costa Rica early Friday.
Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Some strengthening is possible before landfall, with
weakening expected as the cyclone crosses southern Nicaragua and
northern Costa Rica.
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 estimated minimum central pressure is 981 mb (28.97 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 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 this morning.
WIND: Hurricane conditions are expected within the hurricane
warning area today, with tropical storm conditions expected to begin
in the next few hours. Hurricane conditions are possible in the
hurricane watch area today.
Tropical storm conditions are expected on San Andres overnight.
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 tonight.
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.
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.
