938 AXNT20 KNHC 011630 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1815 UTC Sun Nov 1 2026 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 1200 UTC surface analysis and satellite imagery through 1700 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough axis reaches the Atlantic through the coast of W Africa near 15N18W, and continues southwestward to 12N23W, where it transitions to the ITCZ. The ITCZ then continues to 07N39W and to 12N59W. Numerous moderate to isolated strong convection is seen from 06N to 14N and east of 33W. Scattered moderate convection from 07N to 14N between 33W and 61.5W. ...GULF OF AMERICA... Fresh to strong east winds are over the NE Gulf along with seas of 4 to 6 ft. An upper-level trough is supporting scattered to numerous convection north of 24N and east of 88W. This activity is capable of producing strong gusty winds and heavy rainfall. Elsewhere, light to gentle NE winds prevail along seas 2 to 4 ft. For the forecast, the pressure gradient between high pressure over the SE U.S. and lower pressure over the deep tropics will maintain fresh NE to E winds and moderate seas through the NE Gulf through Mon night. A cold front will move into the NW Gulf Tue, then move slowly E across the basin through Thu night, as high pressure builds in behind it. ...CARIBBEAN SEA... The pressure gradient between higher pressure over the U.S. and the western Atlantic, and lower pressure over Colombia supports fresh trades along with seas of 5 to 7 ft in the south- central Caribbean offshore Colombia. Moderate to fresh trades and seas of 4 to 6 ft are across the remainder of the central and eastern Caribbean. The eastern end of the Pacific monsoon trough is supporting a cluster of moderate convection south of 13N and west 79W. For the forecast, moderate to fresh trades along with moderate seas over the central and eastern Caribbean will continue through Mon, with locally strong winds and rough seas offshore Colombia. The pressure gradient will relax starting Mon night as broad low pressure forms north of the area, leading to overall weaker winds and diminishing seas through Thu. ...ATLANTIC OCEAN... A cold front extends from near 31N48W southwestward to 24N70W, and continues as a trough to 26N82W. Numerous convection is found along and north of the trough from 24N to 29N and west of 73. Elsewhere along the cold front, scattered moderate convection is noted. A secondary cold front extends from 31N58.5W to 30N69W. No significant convection is presently occurring with this front. Fresh to strong northeast to east winds along with seas of 7 to 9 ft are northwest of the first front, north of 24N west of 60W. Farther east, low pressure of 1012 mb is north of the area west of Madeira near 34N24W, with a cold front extending from it to 31N18W and to near 23.5N25W. An area of scattered moderate convection is east of this front to the along and inland the coast of Africa north of 25N. Gentle to moderate north winds and seas of 7 to 10 ft in north swell are behind the front north of 23N between 18W and 32W. Gentle to moderate winds and seas of 4 to 6 ft are elsewhere across the basin. For the forecast west of 55W, the fronts will move SE today and weaken as high pressure builds southward behind it across the western Atlantic. Widespread fresh to strong NE to E winds and rough seas develop behind the front Mon N of 26N and W of 60W as the cold front stalls and the pressure gradient tightens. These conditions will prevail through Tue night, when the front will dissipate. The high pressure in the western Atlantic will slide east Wed into Thu, allowing the next cold front to move offshore Florida late Thu night. $$ KRV
