through Saturday night. A west-northwestward motion is expected to
begin on Sunday and continue into Monday. On the forecast track,
the system will make landfall near the border of Nicaragua and
Costa Rica in the next few hours, 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

Mexico Saturday through Monday.
Maximum sustained winds are near 45 mph (75 km/h) with higher
gusts. Some strengthening is possible before landfall. After
