Tropical Weather Discussion for North America, Central America Gulf of America, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 31N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 0800 UTC.

...SPECIAL FEATURES...

Hurricane Melissa is centered near 35.9N 64.0W at 31/0900 UTC or 220 nm N of Bermuda, moving NE at 36 kt. Estimated minimum central pressure is 973 mb. Maximum sustained wind speed is 80 kt with gusts to 100 kt. Peak seas are currently around 39 ft (12.0 m) just N of the area and W of Bermuda. Numerous moderate isolated strong convection is now confined to N of the area within 43N71W to 47N62W to 34N56W to 33N66W. Melissa is rapidly moving toward the northeast. This general motion is expected to continue into Saturday, followed by a gradual slowdown and turn toward the east-northeast later this weekend. On the forecast track, the center of Melissa is expected to pass to the south of the Avalon Peninsula of Newfoundland as a post-tropical cyclone tonight. Melissa is expected to become a strong post-tropical cyclone later today, with gradual weakening forecast over the weekend. Swells generated by Melissa will continue to affect portions of Hispaniola, Cuba, the Bahamas, the Turks and Caicos Islands, and Bermuda during the next couple of days. These swells are expected to reach the coast of the Northeastern United States and Atlantic Canada today and persist into the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

...TROPICAL WAVES...

A tropical wave has its axis along 57W, south of 18.5N, moving westward at around 10 kt. Deeper convection has diminished during the past several hours with widely scattered showers and isolated thunderstorms possible S of 19N between 50W and 62W.

...MONSOON TROUGH/ITCZ...

The monsoon trough axis enters the Atlantic at the coast of Senegal near 13N16.5W and extends southwestward to near 09N20.5W, where it transitions to ITCZ, continuing to 05N48W. Widely scattered to numerous moderate convection is noted on conventional satellite imagery from 03.5N to 10N between 11W and 28W, and from 01N to 09.5N between 28W and 43W.

...GULF OF AMERICA...

A surface ridge has built across the Gulf in the wake of a departed cold front. Winds behind the front have diminished with moderate winds noted E of 87W and light to gentle winds W of 87W per earlier ASCAT scatterometer data. A lingering area of locally rough seas is in the SE Gulf just N of the Yucatan Channel with slight seas in the far NW waters and moderate elsewhere.

For the forecast, gentle to moderate N to NW winds and moderate seas will diminish and subside today. A cold front will enter the NW Gulf Sat night into Sun, with fresh to locally strong winds and building seas behind the front. The front will reach from the Florida Panhandle SW to off Veracruz, Mexico Sun morning, clearing the basin by Mon morning. Winds and seas behind the front should gradually decrease into midweek.

...CARIBBEAN SEA...

A stationary front extends from eastern Cuba to eastern Honduras, with moderate to fresh winds and moderate seas behind it. A pair of surface trough is analyzed ESE of the front, one from 17N79.5W to 09N81W and the other from SW Haiti near 19N73W to northern Colombia at 10.5N75W. Scattered moderate isolated strong convection is noted S of 11N including near the eastern end of the eastern Pacific monsoon trough, with similar activity noted within 30-60 nm of the eastern trough. Some additional convection is in the far SE Caribbean and near Trinidad and Tobago. Moderate E-SE winds are E of 72W, with mainly light to gentle winds between 72W and the western trough. Winds W of the western trough to the front are moderate to fresh. Seas are 3-5 ft E of the western trough, and 4-7 ft elsewhere.

For the forecast, the front will wash out today, becoming a stationary remnant trough into the weekend. Trade winds will freshen, locally strong, over the E Caribbean tonight into Sat as the pressure gradient between a tropical wave entering the region and a ridge building N of the area tightens. These winds will expand to the central Caribbean by Sat evening as the wave continues to move westward and the ridge further builds, with seas locally to rough. Easterly winds will diminish to moderate speeds early next week as the wave weakens and the ridge starts retreating eastward, loosening the pressure gradient. Meanwhile, another cold front may push into the NW Caribbean by early Mon, reaching from eastern Cuba to just offshore Nicaragua Tue. Moderate to fresh winds will follow the front, locally strong offshore Nicaragua into midweek.

...ATLANTIC OCEAN...

Please read the Special Features section for the details related to Hurricane Melissa.

Hurricane Melissa is N of the area near 35.9N 64.0W at 5 AM EDT, and is moving northeast at 36 kt. Maximum sustained winds are 80 kt with gusts to 100 kt, and the minimum central pressure is 973 mb. A cold front is to the W of Melissa from 31N70.5W to 21.5N76.5W. Fresh to strong winds and reinforcing seas are behind this front. Ahead of the front and N of Hispaniola, a surface trough is supporting scattered showers between 58W and 74W. A frontal trough is well to the E, from 31N34W to 23.5N43W with scattered moderate convection N of 27N between 29W and 38W. Moderate to locally fresh winds are N of 26N between 25W and 48W with seas to 8 ft near 31N and near the front. Moderate to fresh trades are S of 17N between 35W and 60W with 6-8 ft seas in the wake of the tropical wave discussed above and with a building ridge reaching from the Canary Islands southwestward through 22N35W, then to the WNW to 27N53.5W. Winds are moderate or weaker with 4-7 ft seas across the remainder of the waters including under the ridge.

For the forecast west of 55W, Melissa will become extratropical and move to well N of the area 40.4N 58.9W this afternoon. A cold front W of Melissa from 31N70.5W to the SE Bahamas and eastern Cuba with fresh to strong winds and reinforcing seas behind it will quickly weaken today as it moves E and Melissa departs, reaching from 31N60W to near the Windward Passage by this evening where it will stall and dissipate into the weekend, then shift NW as a remnant trough through Sun night. Remnant seas from Melissa will more slowly subside through Sat. Another cold front may impact the region early next week.
