DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Bonnie was
located near latitude 11.1 North, longitude 81.8 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 remain 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 estimated central pressure is 1005 mb (29.68 inches).
