The tropical wave is passing through Honduras, Nicaragua, and Costa Rica. Broad upper level cyclonic wind flow is along the western coast of Central America. Numerous strong rainshowers are along the W coast of Central America, from Costa Rica to Nicaragua, and within 120 nm of the coast of El Salvador and Guatemala. The monsoon trough is along 09N/10N between 74W in Colombia and 86W in the eastern Pacific Ocean. Isolated moderate to locally strong rainshowers are in the SW corner of the Caribbean Sea from 14N southward from 76W westward. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal areas of Guinea near 10N14W, to 09N20W, 09N27W, and 08N29W. The ITCZ continues from 08N29W to 06N35W and 07N42W.

A surface trough cuts through Georgia and the Florida Big Bend into the NE Gulf of Mexico near 28N84W. Isolated moderate to locally strong rainshowers are within 100 nm of the coast of the U.S.A. from SE Louisiana toward the E and SE, to Florida near 25N. Weak high pressure will dominate the western Gulf of Mexico into mid week. It is possible that a low pressure center may form along a trough in the NE Gulf of Mexico by the middle of the week. The low pressure center is forecast intensify slowly through Friday, as it drifts westward. Strong to near gale-force winds and building seas for the north central Gulf of Mexico will be generated.

Numerous strong rainshowers are along the W coast of Central America, from Costa Rica to Nicaragua, and within 120 nm of the coast of El Salvador and Guatemala. The monsoon trough is along 09N/10N between 74W in Colombia and 86W in the eastern Pacific Ocean. Isolated moderate to locally strong rainshowers are in the SW corner of the Caribbean Sea from 14N southward from 76W westward. High pressure to the north of the area will support fresh to strong trade winds in the south central Caribbean Sea during the entire period. A tropical wave will move across the Lesser Antilles on Tuesday, with strong winds affecting mainly the Windward Islands. Rainshowers and thunderstorms that are associated with this wave will affect the SE part of the basin through the middle of the week. ATLANTIC OCEAN...
