At 400 PM EST (2100 UTC), the center of Hurricane Otto was located
near latitude 10.5 North, longitude 79.6 West. Otto is moving toward
the west near 2 mph (4 km/h).  Otto should move a little faster
toward the west or west-northwest for the next couple of days.  On
the forecast track, Otto is expected to approach the coasts of Costa
Rica and Nicaragua on Thursday.

Maximum sustained winds have increased to near 75 mph (120 km/h)
with higher gusts.  Additional strengthening is expected for the
next couple of days until landfall.

Hurricane-force winds extend outward up to 10 miles (20 km) from the

(110 km).

The estimated minimum central pressure is 984 mb (29.06 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
