DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Pilar was
located near latitude 11.4 North, longitude 89.8 West. Pilar is
moving toward the east-northeast near 3 mph (6 km/h).  A slower 
northeastward motion is expected to begin later today.  Pilar is 
forecast to move little tonight and early Wednesday.  On the 
forecast track, Pilar could move a little closer to the coast of El 
Salvador or Nicaragua late today through early Wednesday, though 
the core of the system is expected to remain offshore.  The storm 
is forecast to begin moving west-southwestward away from land by 
Thursday.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Some slight strengthening is possible over the next day or so
before gradual weakening likely begins on Thursday.
 
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
 
The estimated minimum central pressure is 1000 mb (29.53 inches).

RAINFALL:  Pilar is expected to produce storm total rainfall of 5
to 10 inches, with local amounts to 15 inches, over portions of
Central America from southern El Salvador, across southern Honduras,
western Nicaragua into northern Costa Rica through Wednesday.  This
rainfall will produce flash and urban flooding, along with mudslides
in areas of higher terrain.
 
SURF:  Swells generated by Pilar are expected to continue affecting
the Pacific coast of Central America during the next few days. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
 
WIND:  Tropical storm conditions are possible within the Tropical
Storm Watch area during the next day or so.
