Tropical Weather Discussion

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.
Central Atlantic Significant Swell: A cold front will continue to move E across Central Atlantic waters through Wed, with strong to near gale-force N winds behind it. Significant NW to N swell, with period of 8 to 12 seconds, generated by gales N of the region is combining with wind-waves to induce very rough seas SE of Bermuda that will spread SE across waters N of 21N into Wed night. Widespread seas of 12 to 17 ft can be expected from 35W to 67W during this period. Another cold front may bring similar conditions late this week.
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 information.
The monsoon trough enters the eastern Atlantic near 06N10W and extends southwestward to 04N20W to 03N27W. The ITCZ extends from 03N27W to 03N37W to 02N48W. Scattered moderate convection is noted from 01N to 05N between 02W and 19W, and from 02S to 02N between 44W and 50W.
A surface trough prevails over the far SW Gulf from N of Tampico to the offshores of Veracruz, which continues to generate scattered to isolated showers. Surface ridging dominates elsewhere. Moderate to fresh winds and moderate seas are ongoing over much of the eastern half of the basin, except for fresh to strong E winds across the Florida Straits where seas are rough. West of 90W, winds are moderate or weaker and seas are slight to moderate.
For the forecast, strong high pressure centered off the Mid- Atlantic States will move eastward farther into the western Atlantic today. This system will support fresh to strong winds and moderate to rough seas across the Straits of Florida and the SE Gulf through today, then mainly fresh winds will prevail through Wed night. A ridge will remain in control of the weather pattern across the Gulf region trough the middle of the week. A high pressure center will settle over the NE Gulf Thu through Fri producing mainly a gentle to moderate wind flow.
Strong high pressure over and offshore the Carolinas continues to build southward, tightening the pressure gradient between it, the Colombian low and a cold front with tail reaching the Turks and Caicos this morning. This is resulting in the continuation of fresh to strong trades in the central and western basin with moderate to rough seas, highest off Colombia. Moderate or weaker winds are over the eastern Caribbean E of 68W while seas remain in the 4 to 6 ft range.
For the forecast, strong high pressure N of the area combined with the Colombian low will support fresh to strong winds in the lee of Cuba, the Windward Passage, and the central Caribbean through Thu night, except through Sat night off Colombia. Otherwise, long period northerly swell will reach the NE Caribbean and the waters just E of the Leeward Islands, including the Atlantic passages, by Wed morning and subside late Thu.
See Special Features section above for information on significant swell that will bring very rough seas to parts of the central Atlantic into mid-week.
A cold front extends from 31N51W to the Turks and Caicos Islands. Behind the cold front, strong to near gale-force NE winds are ongoing along with very rough seas to 16 ft. Ahead of the front, a pre-frontal trough is generating scattered heavy showers N of 23N between the front and 45W. The remainder subtropical Atlantic is under the influence of broad high pressure of 1025 mb centered just to the S of the Azores Islands. Winds from 20N to 30N and E of 45W are moderate or weaker, except moderate to fresh between the coast of NW Africa and the Cape Verde Islands where seas are rough to 10 ft. In the tradewind belt S of 20N from Africa to the Lesser Antilles, moderate or weaker trades and seas to 7 ft dominate.
For the forecast W of 55W, the cold front will rapidly progress eastward reaching the SE waters later this morning. At that time, the cold front will extend approximately from 25N55W to eastern Cuba near 21N76W. Then, the front will reach from 22N55W to 20N74W by Wed morning while dissipating. Strong winds and rough to very rough seas in northerly swell are expected in the wake of the front through the middle of week. A second cold front is forecast to reach the N waters on Wed, and extend from 30N55W to the NW Bahamas by Thu morning. Strong winds and rough seas are expected behind the front. A third cold front will move across the northern offshore waters Thu night into Fri 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
