The southernmost point of a cold front reaches 23N74W in the SE
Bahamas. A surface trough, the remnants of an already-dissipated
front, is along 18N83W 17N86W, into southern Belize. Widely
scattered moderate to isolated strong rainshowers are from 15N to
19N southward from 80W westward.

The monsoon trough is along 08N/09N between 75W/76W in Colombia
and 83W/84W in the southern parts of Costa Rica. Upper level
anticyclonic wind flow spans the SW corner of the Caribbean Sea.
A middle level inverted trough covers the SW corner of the
Caribbean Sea. 700 mb NE wind flow also is moving across the SW
corner of the area. Isolated moderate rainshowers are from 12N
southward from 75W westward. Scattered moderate to strong
rainshowers are in the eastern Pacific Ocean from 05N to 08N from
83W eastward.

A surface trough, the remnants of a dissipating stationary front,
is just north of the Gulf of Honduras along 18N83W into southern
Belize. Convergence along this trough will continue to support
scattered rainshowers, as well as fresh to strong winds through
this morning. Strong surface high pressure, building N of the
area, is supporting fresh to strong winds along the coast of
Colombia. These winds and associated seas will prevail through
early Tuesday, as the center of high pressure shifts eastward
across the NW Atlantic Ocean waters. Large swell in the
Atlantic Ocean waters will persist through Tuesday night.
