The Monsoon Trough extends from the coast of Guinea near 13W to 19W. The ITCZ continues from 19W to 30W to the coast of Brazil near 45W. Scattered moderate convection is from 04N- 04S between 30W-50W.
Gulf of Mexico
As of 01/1500 UTC, a cold front extends from the straits of Florida at 80W to 90W to the bay of Campeche at 97W. Scattered showers are within 45 nm of the front. Strong north winds are over the east Gulf east of 90W, north of the front.
The cold front will cross the Yucatan channel this evening. Fresh to locally strong northwest winds following the front over the northeast Gulf will diminish tonight. Then, winds and seas will remain relatively tranquil through the upcoming weekend as high pressure builds over the northeast Gulf.
Strong winds are occurring off the coast of Colombia, otherwise gentle to moderate winds prevail as high pressure continues to settle into the basin. Dry conditions are also being observed except along the coast of Costa Rica and west Panama.
As high pressure over the west Atlantic weakens and moves southeast, winds and seas in the Caribbean will remain fairly tranquil through the rest of the week. A cold front will pass through the Yucatan channel this evening, then stall along 20N thu and dissipate by fri. Winds will freshen through the windward passage and in the Lee of Cuba fri night through the weekend.

A cold front is presently over the west Atlantic from 68W to the straits of Florida near 80W. An area of broken cold air stratocumulus clouds clouds are over the west Atlantic behind the cold front. Another cold front stretches from 34W to 50W to 56W. Still a third cold front is located in the eastern Atlantic from 26W to 39W. Scattered showers and thunderstorms are occurring along both of these boundaries. A 1015 mb high pressure is centered just north of the Virgin Islands near 58W.
The western cold front will move quickly east, passing Bermuda and the Bahamas tonight, then just north of Puerto Rico fri. Intensifying low pressure off the mid-Atlantic coast will pull this front across the waters this evening through thu night. Gale force southwest winds and very large seas will prevail ahead of the front north of 28N through this evening. Gale force winds may develop over the far west Atlantic fri into early sat as the associated low pressure system dives southeast and passes just north of the forecast waters. Northerly swell will produce large seas across the southwest north Atlantic waters through the weekend.
