Monsoon Trough Itcz

The monsoon trough enters the Atlantic near 09N13W and extends to 05N19W. The ITCZ continues from 05N19W to 05S35W. Scattered moderate and isolated strong convection is noted from 00N to 05N between 19W and 26W.

Gulf Of America

A stationary front extends across the northern Gulf coast from N Florida Panhandle to Texas. South of this boundary, a 1022 mb high pressure centered near 25N86W. Gentle to moderate winds prevail west of the Yucatan peninsula with light to gentle winds elsewhere. Seas are 3 ft or less.

For the forecast, high pressure will remain in control of the weather pattern across the Gulf waters through Fri, bringing light to gentle SE winds. Southerly winds will increase to moderate to fresh speeds Fri night ahead of a cold front that will moves across the west and central waters Sat night and Sun. Strong winds and rough seas are expected in the northern Gulf with this frontal system, forecast to move SE of the area late on Mon.

Caribbean Sea

The pressure gradient between a ridge N of the area and the Colombian low is supporting fresh to strong winds over the south central Caribbean. Seas are in the 7-10 ft range over these waters. Moderate to fresh winds generally prevail elsewhere, except gentle to moderate over the NW Caribbean. Seas over these waters are in the 4-7 ft range.

For the forecast, pulsing winds to near gale-force are expected near the coast of Colombia again tonight due to the pressure gradient between the Colombia/Panamanian low and high pressure centered N of the region. Winds will continue to pulse to strong speeds nightly thereafter, with moderate to rough seas. Elsewhere, moderate to fresh trades and moderate seas will prevail through the upcoming weekend.

Atlantic Ocean

A cold front has entered the waters from 31N67W to N Florida. Strong to near- gale force winds and seas of 8-12 ft prevail N of 27N and southeast of the front to 55W. N of the front, gentle to moderate winds, and seas of 6-8 ft, prevail. High pressure with gentle to moderate winds prevail over the remainder of the discussion waters. Seas are generally in the 8-10 ft range E of 55W, and 4-6 ft elsewhere.

For the forecast west of 55W, a cold front has entered the north waters and extends from near Bermuda to N Florida. Ahead of the front, strong SW to W winds will prevail N of 28N, along with rough to very rough seas. These hazardous marine conditions will spread east through tonight, then diminish Fri as the front weakens. By Fri night the cold front will extend from near 31N55W to the SE Bahamas, and the boundary will sag SE and out of the area Sat night. On Sun, S winds will increase to strong speeds offshore Florida, in advance of
