Interests elsewhere along both the Caribbean and Pacific coasts of
Nicaragua and Costa Rica, as well as the Pacific coasts of El
Salvador, Guatemala, and southern Mexico, should monitor the
progress of this system.

products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Bonnie was
located near latitude 11.2 North, longitude 81.0 West. Bonnie is
moving toward the west near 20 mph (31 km/h) and a continued 
westward motion with a gradual decrease in forward speed is 
expected through Saturday night.  A west-northwestward motion is 
expected to begin on Sunday and continue into Monday.  On the 
forecast track, the system will move across the southwestern 
Caribbean Sea today, cross southern Nicaragua or northern Costa 
Rica tonight, and emerge over the eastern Pacific Ocean on Saturday. 
The system will then move offshore of but parallel to the coasts of 
El Salvador, Guatemala, and southern Mexico Saturday through Monday.

Maximum sustained winds are near 40 mph (65 km/h) with higher 
gusts.  Bonnie is expected to strengthen before it makes landfall 
tonight.  After landfall, short term weakening is forecast on 
Saturday, but Bonnie is expected to restrengthen later this weekend 
and early next week over the eastern Pacific.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
north of the center.

The minimum central pressure is estimated to be 1005 mb (29.68 
inches) based on data from the Air Force Hurricane Hunters.
