Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Thu Oct 16 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.
Atlantic Large Swell Northerly swell generated from a developing gale force low over the Atlantic waters N of the discussion area will generate large northerly swell. Very rough seas, with seas greater than 12 ft, generated from the swell will propagate into the discussion waters between 65W and 70W on Friday. The area if 12 ft seas will spread SE, covering the waters N of 27N between 50W and 68W by Sat night. The swell will then start to subside over the discussion waters, falling below 12 ft Sun night. Seas with this swell will peak near 18 ft over the waters N of 30N between 55W and 60W Sat.
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.
The axis of an eastern Atlantic tropical wave is near 31W/32W S of 18N, and moving west around 15 kt. Scattered moderate to isolated strong convection is noted from 06N to 12N between 30W and 34W.
The axis of a central Atlantic tropical wave is near 44W S of 15N, and moving west around 15 kt. Scattered moderate and isolated strong convection is noted from 05N to 10N between 38W and 48W.
The monsoon trough enters the Atlantic near 11N16W and extends SW to near 08N22W to 09N33W. The ITCZ continues from 09N33W to 08N33W. It resumes from 07N45W to 07N50W. Aside from convection noted in the tropical waves section, scattered moderate and isolated strong convection is noted from 02N to 13N between 10W and 20W.
A surface trough extends from the central Gulf SE to the Yucatan channel. Scattered moderate and isolated strong convection is in the vicinity of the trough. High pressure dominates the remainder of the Gulf waters. Gentle to moderate winds are noted E of 90W, with light to gentle winds W of 90W. Seas are in the 2-4 ft range E of 90W and 1-2 ft W of 90W.
For the forecast, a ridge will dominate the Gulf region, resulting in gentle to moderate winds and slight to moderate seas over much of the basin.
A cold front extends from the Atlantic waters across Hispaniola and Jamaica. Scattered moderate and isolated strong convection is in the vicinity of the front. A weak pressure gradient prevails across the Caribbean waters. Gentle to moderate winds are over the far eastern Caribbean with light to gentle winds elsewhere. Seas are in the 2-3 ft range in the far eastern Caribbean, and 2 ft or less elsewhere.
For the forecast, a weak pressure gradient will support moderate or lighter winds and slight to moderate seas over much of the basin through Sat. A tropical wave will move across the tropical Atlantic waters late this weekend with fresh to strong winds, and rough seas accompanying the wave. The tropical wave is forecast to enter the Caribbean waters by early next week, bringing fresh winds and rough seas over the eastern Caribbean waters.
Please refer to the Special Features section for further details on large swell impacting the area waters Fri through the weekend.
A cold front extends from 31N56W SW to Hispaniola. Scattered moderate to strong convection is within 60 nm east of the front. Fresh to strong winds are N of 25N and E of the front to 50W. Gentle to moderate winds are W of the front. Elsewhere N of 20N, high pressure dominates the Atlantic discussion waters anchored by a 1018 mb high centered near 23.5N28.5W. The 1008 mb remnant low of Lorenzo is centered near 25N41W. Scattered moderate convection is in the vicinity of the low. The pressure gradient between the high and Lorenzo remnants is supporting fresh to strong winds over the waters N of 25N between 31W and 40W. Light winds are around the high center. Gentle to moderate winds are noted elsewhere. Seas of 8-12 ft prevail over the waters N of 25N between 30W and 75W. Elsewhere, seas are in the 4-7 ft range.
For the forecast W of 55W, a series of cold fronts will move across the forecast waters through Sat. High pressure will then build in the wake of the fronts. Fresh to strong winds are expected across the waters N of 25N through at least Sat before winds diminish. The fronts will usher in northerly swell across the forecast waters. Rough seas will cover the waters N of 25N through the end of the week, before spreading southward to cover much of the waters E of 70W by Sat. Seas will then subside from west to east the remainder of the weekend into early next week. Very rough seas will move into the waters N of 27N and E of 70W from early Fri through Sat night.
Our Tropical Weather reports - for the most part are put together only during tropical weather season. Our reports are based on a number of online sources and are based on our past experience dealing with tropical weather. We also occasionally include non-tropical weather that would affect the area / footprint that we cover. For additional information check out Crown Weather Services
