DISCUSSION AND OUTLOOK
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Bonnie was
located just inland over southeastern Nicaragua near latitude 10.9
North, longitude 83.8 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 into Saturday night. A
west-northwestward motion is expected to begin late Saturday night
or on Sunday and continue into Monday. On the forecast track,
the system will move across southern Nicaragua and 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.
Reports from an Air Force Reserve Hurricane Hunter aircraft indicate
that before landfall maximum sustained winds increased to near 50
mph (85 km/h) with higher gusts. Weakening is likely while the
center of Bonnie crosses Nicaragua and Costa Rica. The storm
is forecast to re-intensify over the eastern Pacific Saturday night
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.
The minimum central pressure estimated from the Hurricane Hunter
aircraft data is 997 mb (29.44 inches).
