273 AXNT20 KNHC 072226 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Wed Oct 8 2025 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 1800 UTC surface analysis and satellite imagery through 2200 UTC. ...SPECIAL FEATURES... Tropical Storm Jerry is centered near 12.0N 46.4W at 07/2100 UTC or 1030 nm ESE of the Northern Leeward Islands, moving W at 20 kt. Estimated minimum central pressure is 1003 mb. Maximum sustained wind speed is 45 kt with gusts to 55 kt. Seas are peaking between 12 and 15 ft just north and east of the center. Numerous moderate to isolated strong convection within 120 nm of the center. A decrease in forward speed and a turn to the west- northwest is expected during the next couple of days. On the forecast track, the core of the system is expected to be near or to the north of the northern Leeward Islands late Thu and Fri. Steady strengthening is forecast, and Jerry is expected to become a hurricane in a day or so. 2 to 4 inches of rain are expected Thu across the Leeward Islands due to Jerry. This rainfall brings a risk of flash flooding, especially in areas of higher terrain. Swells generated by Jerry are expected to reach the Leeward Islands on Thu, and will likely cause life- threatening surf and rip current conditions. Please consult products from your local weather office Please read the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.SHTML for more details.

Significant Rainfall Across Eastern Mexico: An upper-level low and its related surface trough will gradually drift westward across the Bay of Campeche toward eastern Mexico over the next few days. Aided by abundant tropical moisture across the region, there is a high potential for heavy rain for the coastal areas from southern Tamaulipas State southward to southern Veracruz State, including the eastern parts of San Luis Potosl, Hidalgo and Puebla States. The heaviest rainfalls are expected near the Tamaulipas/San Luis Potosi border, and across northern and central Veracruz State. With the ground in the region already saturated from earlier rainfall, this will greatly increase the chance for flash and urban flooding. Please stay up to date with the latest forecast and possible flood statements from your local weather agency. ...TROPICAL WAVES... An eastern Atlantic tropical wave is east of the Cabo Verde Islands near 20W from 20N southward, and moving west at 5 to 10 kt. Scattered moderate convection is from 04N to 07N between 17W and 24W. A tropical wave is over the eastern Caribbean along 64W, moving west around 10 kt. Numerous moderate convection is active from 16N to 21N between 61W and 65W. Scattered moderate convection is farther south from 12N to 16N between 61W and 65W. A tropical wave is over the western Caribbean along 75W, moving west at 5 to 10 kt. Scattered moderate convection is from 17N to 21N between 75W and 80W. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic along the Senegal coast just south of Dakar, then curves west-southwestward across 10N23W to 09N33W. Widely scattered moderate convection is present south of the trough from 01N to 06N between 17W and 37W. ...GULF OF AMERICA... Please refer to the Special Features section on potential heavy rain across eastern Mexico. Scattered thunderstorms and fresh to strong E winds follow a trough moving west across the Bay of Campeche in the southwest Gulf. Seas are 3 to 5 ft in this area. Moderate E winds and 2 to 4 ft seas over the northeast Gulf follow another trough south of Mobile Bay in the north-central Gulf. Gentle breezes and 1 to 3 ft are noted elsewhere. For the forecast, high pressure across the eastern U.S. will build modestly across the Gulf basin throughout the week. Moderate E to SE winds and slight to moderate seas will become moderate to locally fresh NE to E through the remainder of the week. A trough of low pressure located over the Yucatan Peninsula is producing a large area of disorganized showers and thunderstorms. This system is expected to emerge over the Bay of Campeche later today, and some slow development is possible before it moves inland over southern Mexico late Wednesday or early Thursday. Regardless of development, showers and thunderstorms and strong gusty winds are likely across waters north of the Yucatan Peninsula and across the southwestern Gulf through Wed night. A cold front is expected to sink southward across the northern Gulf Thu night through Fri. ...CARIBBEAN SEA... Please read the Special Features section about newly formed Tropical Storm Jerry in the central tropical Atlantic which might affect the northern Leeward Islands toward the weekend. In addition to the thunderstorms discussed in the Tropical Waves section, trade wind convergence is supporting a few showers and thunderstorms over the southwest Caribbean between Colombia and Nicaragua. Gentle to moderate E to SE breezes dominate the basin this evening. NE swell from the Atlantic is penetrating through the Mona and Anegada Passages, supporting 3 to 5 ft combined seas reaching the coast of central Venezuela and northeast Colombia. Elsewhere, generally 2 to 4 ft seas are noted across the basin. For the forecast, the main forecast issue will be the impact of Jerry on the northern Leeward Islands Thu and Fri. Elsewhere, moderate trade winds will persist across the south- central basin. Moderate E to SE winds will pulse to fresh in the Gulf of Honduras through tonight. ...ATLANTIC OCEAN... Please refer to the Special Features section at the very beginning on newly formed Tropical Storm Jerry. A stationary front extends southwestward from the northeastern Atlantic across 31N42W and 25N60W to near the northwest Bahamas, then continues as a surface trough to the Florida Straits. Scattered showers and thunderstorms are active along the front. Fresh to strong E winds and 7 to 10 ft seas are evident north of the front. Farther east, fresh to strong NE winds and 7 to 10 ft seas are noted over the eastern Atlantic, mainly north of 15N and east of 30W. Saharan dust is also noted in this region. Gentle to moderate breezes and 5 to 7 ft seas primarily in northerly swell persist elsewhere, outside the main impact area of Jerry. For the forecast west of 55W, Jerry will move to 12.8N 49.4W Wed morning, strengthen to a hurricane near 14.2N 53.0W Wed afternoon, 15.5N 56.4W Thu morning, 17.2N 59.3W Thu afternoon, 18.9N 61.2W Fri morning, and 21.1N 62.6W Fri afternoon. Jerry will change little in intensity as it moves to near 25.8N 63.3W Sat afternoon. Elsewhere, rough seas in N to NE swell across the regional waters will gradually subside from north to south over the Atlantic waters through tonight. Fresh to strong NE to E winds north of a stationary front extending from the central Atlantic near 28N55W to 24N68W then through the NW Bahamas will diminish early this evening. Winds will diminish midweek as the front drifts northward and dissipates. $$ Christensen
