ARC Weather Forecast 15/12/2016

Synopsis: Relatively weak ridging from mid-ocean high pressure covers waters from the S Bahamas E to the NE Caribbean and this ridging will retreat E to be confined to the NE Caribbean by tomorrow. A cold front will move SE over S Florida through midday tomorrow and then will continue moving over the Central Bahamas through the 16th, where it will stall and gradually dissipate through the 18th. Behind this front, strong ridging from broad high pressure over the Central U.S. will build across Florida by tomorrow night. The ridging will remain strong as it expands S over the Bahamas through Hispaniola during 16/12. By 17/12, the strong ridging will encompass waters from the Florida Straits through the NE Caribbean and will persist as such through 18/12.

Conclusion: Fresh E winds cover the remaining grids (QQ, RR and LL) and are forecast to ease slightly across Grids RR and LL by late on 15/12 but will then increase again by the morning of 16/12. Strong ENE winds can be expected across the middle part of Grid QQ by the afternoon of 16/12 and then will expand across Grid RR and most of Grid QQ by the morning of 17/12. Moderate to short period swells will abate slightly through the morning of 16/12, but then will build again from east to west across Grid QQ by late on 16/12 through morning of 17/12.
