DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1000 PM EST (0300 UTC), the center of Hurricane Otto was located
near latitude 10.7 North, longitude 79.8 West. Otto is moving toward
the west-northwest near 3 mph (6 km/h).  A westward to
west-northwestward motion and an increase in forward speed are
expected during the next couple of days.  On the forecast track,
the center of Otto is expected to move near or over the coasts of
southern Nicaragua and northern Costa Rica on Thursday.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Gradual strengthening is expected until the hurricane makes
landfall in Central America.

Hurricane-force winds extend outward up to 10 miles (20 km) from the
center and tropical-storm-force winds extend outward up to 60 miles
(95 km).

The estimated minimum central pressure is 988 mb (29.18 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  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 Wednesday.  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.

WIND:  Hurricane conditions are expected within the hurricane
warning area on Thursday, and are possible in the hurricane watch
area in Costa Rica and Nicaragua on Thursday.  Tropical storm
conditions are expected within the warning area in Panama tonight
and in the warning area in Nicaragua on Wednesday night and
Thursday. Tropical storm conditions are also possible in the
tropical storm watch area in Panama on Wednesday and in San Andres
by late Wednesday.

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.
