DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Tropical Storm Bonnie was 
located inland along the Nicaragua-Costa Rica border near latitude 
11.0 North, longitude 84.5 West. Bonnie is moving toward the west 
near 16 mph (26 km/h), and a continued westward motion with a 
gradual decrease in forward speed is expected later today.  A 
west-northwestward motion is expected to begin tonight or on Sunday 
and continue into Monday.  On the forecast track, Bonnie will move 
across southern Nicaragua and northern Costa Rica during the next 
several hours and emerge over the eastern Pacific Ocean later this 
morning.  Bonnie will then move offshore of but parallel to the 
coasts of El Salvador, Guatemala, and southern Mexico today through 
Monday.

Maximum sustained winds have decreased to near 45 mph (75 km/h) with 
higher gusts.  Additional weakening is likely during the next 
several hours while the center of Bonnie crosses Nicaragua and Costa 
Rica.  The storm is forecast to re-intensify over the eastern 
Pacific beginning later today and continuing through Monday.

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

The estimated minimum central pressure is 999 mb (29.50 inches).
