East Atlantic Significant Swell Event: 1004 mb low pressure is located over the far eastern Atlantic between Madeira and the Canary Islands. Large NW swell has been moving through the eastern North Atlantic over the past several days. Seas of 12 to 15 ft continue north of 25N and between 20W and 30W, being generated by a gale- producing low pressure NE of the region. These very rough seas will persist through early today, before subsiding as the low pressure weakens. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center, at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details. ...MONSOON TROUGH/INTERTROPICAL CONVERGENCE ZONE... The monsoon trough extends from Guinea-Bissau to 04N20W, where it transitions to the ITCZ and extends to 03N35W and then to the coast of Brazil near 02S43W. Scattered showers and thunderstorms are active from 01N-06N between 15W-27W. ...GULF OF AMERICA... A 1022 mb high is centered at 27N90W, providing light to gentle winds over the Gulf overnight.

High pressure will build in the wake of the front with moderate to fresh S return flow developing over the W Gulf Sun and Mon. ...CARIBBEAN SEA... A stationary front extends from E Cuba to Honduras with N winds moderate to fresh behind the front. A moderate pressure gradient between the Bermuda-Azores High well northeast of the basin to a 1009 mb Colombian Low is forcing fresh to strong trades over the south-central Caribbeans. Elsewhere, winds are gentle to moderate. Seas are 4-7 ft over the NW Caribbean, 4-6 ft over the south- central Caribbean, and 2-4 ft elsewhere. The Mona and Anegada Passages are experiencing 5-6 ft N swells. Scattered showers are occurring within 60 NM of the front. For the forecast, the stationary front will dissipate later today. The remnants of the front will strengthen winds off Nicaragua Fri and continue through the weekend before diminishing on Mon.

Elsewhere, a moderate pressure gradient between a 1030 mb Bermuda-Azores High at 34N44W to lower pressure within the ITCZ is forcing moderate to fresh trades south of 20N with seas 8-10 ft in mixed wind waves and N swell. For the forecast west of 55W, the near gale NE winds associated with the low north of 28N between 74W-78W will steadily diminish today. The low will gradually weaken through the end of the week, with conditions improving. A new cold front will move off the coast of Florida late Fri. The front will progress across the forecast waters, followed by fresh to strong W to NW winds north of 29N Sat into Mon. High pressure will build in the wake of the front by early next week. Rough seas in N swell over the Atlantic waters east of the Lesser Antilles will subside later today. $$ Landsea
