DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1000 PM EST (0300 UTC), the center of Hurricane Otto was located
near latitude 11.2 North, longitude 82.2 West. Otto is moving toward
the west near 9 mph (15 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.

Maximum sustained winds are now near 85 mph (140 km/h) with higher
gusts.  Additional 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 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 tonight.

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 tonight.
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 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.
