000 AXNT20 KNHC 060554 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Sat Feb 06 2021 Tropical Weather Discussion for North America, Central America Gulf of Mexico, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 32N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0530 UTC. ...SPECIAL FEATURES... ...GALE-FORCE WINDS FOR THE CARIBBEAN SEA... NE-to-E gale-force winds, and sea heights ranging from 10 feet to 12 feet, are present, in the coastal waters of Colombia, from 11N to 12N between 74W and 76W. The wind speeds will slow down to less than gale-force by Friday morning. Please, refer to the following website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml, for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal sections of Sierra Leone near 07N12W, to 04N20W. The ITCZ continues from 04N20W, to 02N30W, and 01N38W. Precipitation: scattered strong is from 03N to 07N between 10W and 12W. Isolated moderate to locally strong is from 07N southward between 10W and 24W. Isolated moderate rainshowers are elsewhere from 10N southward from 60W eastward. GULF OF MEXICO... A cold front extends from the border of SE Georgia and Florida, across north central Florida, into the north central Gulf of Mexico, to NE coastal Mexico. Precipitation: broken to overcast multilayered clouds and possible rainshowers are from 25N northward. Other broken to overcast multilayered clouds and possible rainshowers cover the Gulf of Mexico from 27N southward from 88W eastward. A surface trough is along 26N94W to the coast of Mexico near 20N97W. Precipitation: broken to overcast multilayered clouds and possible rainshowers are from 24N southward from 94W westward. The current cold front, from the Florida Bend Bend to the Texas/Mexico border, will stall overnight. The front will begin to move northward as a warm front on Saturday, but be replaced by a reinforcing cold front. This merged cold front then will stall on Sunday, from near Fort Myers Florida to the Bay of Campeche. Looking ahead, the front will move northward and dissipate early next week. Moist southerly flow may allow areas of fog across the northwest and north central Gulf of Mexico early next week. CARIBBEAN SEA... An upper level trough is 150 nm to the southwest of the line from NW Cuba to the Dominican Republic. Precipitation: isolated moderate from 18N northward between 76W and 85W. Broken to overcast low level clouds, and isolated moderate rainshowers, span the rest of the Caribbean Sea. The clouds and isolated moderate precipitation are moving with the surface-to-low level wind flow. Some of the those clouds are from 16N southward from 75W westward, and from 70W eastward. High pressure, building to the north of the Caribbean Sea, will support fresh to strong trade winds in the south central Caribbean Sea into mid week. The winds will pulse to gale-force nightly, through the weekend, off the coast of Colombia. ATLANTIC OCEAN... A stationary front extends from 32N50W to 31N52W. The stationary front is dissipating from 31N52W, to 25N60W, 20N70W, to the interior sections of the NW part of the Dominican Republic from 19N to 20N between 70W and 71W. Precipitation: widely scattered moderate to isolated strong is from 31N to 33N between 47W and the frontal boundary. Nearby precipitation that is mostly not related to the frontal boundary: broken to overcast multilayered clouds and isolated moderate rainshowers cover the Atlantic Ocean from 07N northward between 50W and 60W. Broad surface anticyclonic wind flow covers the Atlantic Ocean, on either side of the dissipating stationary front. A ridge extends from a 1026 mb high pressure center, that is near 31N57W, to 29N61W 25N70W and 23N79W. A 1033 mb high pressure center is near 36N35W. The current weakening stationary front, from 22N65W to the Dominican Republic, will dissipate overnight. A weak cold front will move off the NE Florida coast tonight then stall Sat from 31N73W to near Daytona Beach, Florida. Strong S winds will develop N of 28N, as the front moves northward as a warm front, on Saturday night. Another cold front will move off the Florida coast on Sunday morning. This front will move SE, then stall on Monday, from Bermuda to near Miami, Florida, and then lift northward and dissipate through mid week. $$ mt/sk
