For the North Atlantic, Caribbean Sea and the Gulf of America:

Tropical cyclone formation is not expected during the next 7 days.

Today marks the first day of the Atlantic hurricane season, which will run until November 30. The long-term averages for the number of named storms, hurricanes, and major hurricanes are 14, 7, and 3, respectively.

The list of names for 2026 is as follows:

This product, the Tropical Weather Outlook, briefly describes significant areas of disturbed weather and their potential for tropical cyclone formation during the next seven days. The issuance times of this product are 2 AM, 8 AM, 2 PM, and 8 PM EDT. After the change to standard time in November, the issuance times are 1 AM, 7 AM, 1 PM, and 7 PM EST.

A Special Tropical Weather Outlook will be issued to provide updates, as necessary, in between the regularly scheduled issuances of the Tropical Weather Outlook. Special Tropical Weather Outlooks will be issued under the same WMO and AWIPS headers as the regular Tropical Weather Outlooks.

A standard package of products, consisting of the tropical cyclone public advisory, the forecast/advisory, the cyclone discussion, and a wind speed probability product is issued every six hours for all ongoing tropical cyclones. In addition, a special advisory package may be issued at any time to advise of significant unexpected changes or to modify watches or warnings.

NHC has the option to issue advisories, watches, and warnings for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 72 hours. For these land-threatening "potential tropical cyclones", NHC will issue the full suite of advisory and watch/warning products. Potential tropical cyclones share the naming conventions currently in place for tropical depressions, being numbered from a single list (e.g., "One", "Two", "Three", etc.).

The Tropical Cyclone Update is a brief statement to inform of significant changes in a tropical cyclone, to post or cancel watches or warnings, or to provide hourly position updates between intermediate advisories when the storm center is easily followed by radar. It can also be used in lieu of or to precede the issuance of a special advisory package. Tropical Cyclone Updates, which can be issued at any time, can be found under the WMO header WTNT61-65 KNHC, and under AWIPS header MIATCUAT1-5.

Special Features

Atlantic Gale Warning: A cold front enters the tropical Atlantic near 31N60W and continues southwestward to 25N75W, where it becomes a stationary front to NE Florida. A recent scatterometer satellite pass captured strong to gale-force SW winds ahead of the front to 57W and north of 29N. Rough seas are occurring in these waters. Gale-force winds will move north of our area by 0600 UTC. Conditions will improve Mon.

Please read the latest High Seas and Offshore Waters Forecast issued by the National Hurricane Center at websites - https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and https://www.nhc.noaa.gov/marine/offshores.php for more details.

Tropical Waves

An eastern Atlantic tropical wave is along 30W, south of 12N and moving westward at 10 to 15 kt. Scattered moderate convection is present from 02N to 09N and between 24W and 37W.

A central Caribbean tropical wave is along 72W, south of 17N and moving westward at 10 to 15 kt. Relatively dry air over the basin is precluding convection near this wave at this time.

A western Caribbean tropical wave is along 82W, south of 15N and moving westward at around 15 kt. No deep convection is noted around this system.

Monsoon Trough/ITCZ

The monsoon trough enters the Atlantic through the coast of Mauritania near 18N16W, then curves southwestward to 06N29W. The ITCZ extends from 06N29W to 04N51W. Scattered moderate convection is evident from 03N to 13N and east of 24W. Similar convection is seen within 120 nm on both sides of the ITCZ.

Gulf Of America

Divergence aloft and diurnal heating supported the development of showers and thunderstorms over Yucatan during the afternoon and evening hours. The storm activity is currently affecting the eastern Bay of Campeche and off northern Yucatan. A few showers are also noted in the central and eastern Gulf. A weak pressure gradient supports moderate to locally fresh E-SE winds and slight to moderate seas west of a line from SE Louisiana to western Cuba. Elsewhere, light to gentle winds and slight seas prevail.

For the forecast, a ridge will continue to dominate the Gulf waters through midweek supporting gentle to moderate E to SE winds with moderate seas. The exception will be evening pulses of fresh winds off the northern Yucatan Peninsula and in the central Gulf through the same period. An upper-level trough across the western Gulf will continue to support showers and thunderstorms across the east and central Gulf through the early part of the week. Expect fresh to strong E winds and moderate to rough seas across the NE Gulf Wed and Wed night as a frontal boundary reaches the area.

Caribbean Sea

The tight pressure gradient between the subtropical ridge NE of the islands and lower pressures in northern Colombia results in fresh to strong easterly trade winds and seas of 5-8 ft across the central Caribbean. Fresh to locally strong easterly breezes and moderate seas are found in the Gulf of Honduras. Moderate to fresh easterly breezes and moderate seas are noted in the eastern and remainder of the NW Caribbean. Elsewhere, light to gentle winds and slight to moderate seas are prevalent.

Divergence aloft and diurnal heating continue to support scattered showers and thunderstorms over Cuba, Hispaniola, Yucatan and Central America and nearby waters. Drier conditions are present elsewhere in the basin.

For the forecast, the Atlantic ridge combined with the Colombian low will support moderate to fresh trade winds across most of the basin into Mon, with fresh to strong winds and rough seas over the south-central Caribbean. The area of fresh to strong winds and rough seas will expand across the east and central Caribbean Mon night into Tue as the ridge north of the area strengthens. Looking ahead, winds and seas will diminish slightly starting late Wed as the ridge north of the basin weakens.

Atlantic Ocean

Please read the Special Features section about a Gale Warning for waters SE of Bermuda.

A cold front extends from 31N60W to 25N75W, followed by a stationary front to NE Florida. Scattered showers are noted ahead of the front to 55W and north of 24N and west of 76W. Fresh to strong SW winds and rough seas are present ahead of the front to 50W and north of 27W. Rough seas are also present behind the front to 65W and north of 27W. Moderate or weaker winds and moderate seas are occurring in the remainder of the SW North Atlantic (west of 55W, north of 20N).

The rest of the tropical Atlantic are dominated by a broad subtropical ridge anchored by a 1029 mb high pressure system centered near 33N33W. The pressure gradient between this ridge and lower pressures in the deep tropics sustain fresh to locally strong N-NE winds and rough seas east of a line from 31N33W to the northern Leeward Islands. Elsewhere, moderate or weaker winds and moderate seas prevail.

For the forecast west of 55W, the cold front will shift southeastward, reaching from 31N58W to 25N70W by early Mon morning when fresh to strong SW winds and moderate to locally rough seas will continue to affect the NE waters. Meanwhile, another low pressure system will move off northeast Florida by late Mon and shift eastward toward Bermuda by late Tue before dissipating. Associated winds to minimal gale-force are likely southeast of Bermuda by late Tue. Looking ahead, a third low pressure area will dissipate as it moves between northeast Florida and Bermuda Wed and Thu.
