Tropical Storm Gamma near 21.3N 88.0W 990 mb at 11 PM EDT moving NW at 6 kt. Maximum sustained winds 50 kt gusts 60 kt. Gamma will move to 21.8N 88.2W Sun morning, 22.2N 88.5W Sun evening, 22.1N 88.9W Mon morning, 21.8N 89.9W Mon evening, 21.3N 90.9W Tue morning, and 20.7N 91.7W Tue evening. Gamma will change little in intensity as it moves southwestward through the eastern Bay of Campeche. A stationary front from SW Florida near 26N81W to the SE Gulf near 23N86W will dissipate late Sun into Mon, ahead of low pressure expected to move from the northern Caribbean across western Cuba into the southeast Gulf Tue. A cold front will move into the northern Gulf Mon, then stall and dissipate over the central Gulf through mid week as the low pressure moves northward. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Tropical Storm Gamma is over the northern coast of Yucatan near 21.3N 88.0W 990 mb at 11 PM EDT moving NW at 6 kt. Maximum sustained winds 50 kt gusts 60 kt. Gamma will continue to move NW into the south-central Gulf, allowing winds and seas over the Yucatan Channel to diminish through Sun. Meanwhile, another area of low pressure is developing along a tropical wave south of Hispaniola. There is a medium chance this low may form into a tropical depression or tropical storm through late Mon as the low moves through the NW Caribbean. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A stationary front extending from 31N73W to 27N80W will gradually dissipate through early Sun. Another stationary front extending from 31N79W to just N of Cape Canaveral, Florida will dissipate through late Sun. Otherwise, the Bermuda High north of our area will support moderate to fresh trades south of 22N, occasionally pulsing to strong north of Hispaniola during the overnight hours through Sun night. Looking ahead, a third weak front will move over the Atlantic waters east of NE Florida late Sun or early Mon, drift south through Tue then stall from 31N73W to near W Palm Beach Florida by mid week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ019...CENTRAL GULF FROM 22N TO 26N BETWEEN 87W AND 94W...
