From WEATHER ROUTING INC. (WRI)

Synopsis: Good morning. A ridge of high pressure extends from east of the Azores SW across the Central Atlantic through the E Caribbean. This ridge will remain in place through the 10/12, then weaken on the 11/12-12-12 as the gale track north of 30N becomes more active.  A cold front will extend from a gale north of the Azores SW through 27N/40W on the 11/12. This front will track E to waters north of the Canaries through the 14/12. Another cold front will extend from 33N/45W SW to 23N/60W on the 13/12 and will move E over mid-ocean through the 15/12, while weakening.

High pressure will build off the U.S. Coast near the Carolinas on the afternoon of the 12/12. Associated ridging will cover waters across the Bahamas into the N and NE Caribbean. This high will move E towards 32N/60W through the afternoon of the 14/12.

Conclusion: Largest swell is currently in the grid JJ. This swell will propagate S and W into grids PP, QQ, and RR by tomorrow morning. Swell will then begin to ease across the area on the 11/12. Winds across the area are fairly consistent in magnitude as ridging continues to persist across the area. Over waters east of about 50W, the winds are slightly north of east and winds are more E between 50W and the Caribbean. Winds across the whole area will be mostly E by tomorrow afternoon.
