A mid to upper low will meander over the E Gulf of Mexico through the middle of next week supporting showers. A surface trough will develop along the Yucatan Peninsula late each afternoon, drift westward across the southwest Gulf during the overnight hours, then dissipate along 96W during the late mornings. Fresh northeast to east to southeast wind shift is expected in the vicinity of the trough. An east to west ridge will meander across the northern Gulf waters through the period accompanied by a moderate southeast return flow in the W Gulf. Fresh to strong winds and associated seas are expected in the Yucatan Channel and SE Gulf S of 25N Wed evening associated with a tropical wave or developing area of low pressure. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A tropical wave will move west across the Gulf of Honduras through tonight. The wave interacts with an upper trough, thus resulting in the continuation of rainshowers across the NW Caribbean. A second tropical is in the far E Caribbean supporting showers in the Leeward Islands and NE waters. Strong high pressure N of the area continue to support near gale force winds along the NW coast of Colombia. The pressure gradient will relax this afternoon and trades in the south-central basin will diminish to fresh to strong continuing through mid next week. A tropical wave is forecast to move across Central America by Wed and the pressure gradient will tighten, thus resulting in fresh to strong winds in the Gulf of Honduras and NW Caribbean. ...SW N ATLANTIC INCLUDING THE BAHAMAS... An east to west ridge will meander between 27N and 29N through Wed. Fresh to locally strong nocturnal easterly winds are forecast along the northern coast of Hispaniola, with moderate easterly low forecast elsewhere south of the ridge. Gentle to moderate southerly flow is expected north of the ridge. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
