DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM EST (0900 UTC), the center of Hurricane Otto was located
near latitude 11.2 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 expected to begin tonight and continue through early Saturday. On
the forecast 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.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Some 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 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 to reach the hurricane
warning area late this morning or early this afternoon, with
tropical storm conditions expected to begin soon. 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 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.
