WX ARC PLUS 2017 01 DEC



Synopsis: Good morning. High pressure near 26N/51W will move E and merge with a ridge over the Central Atlantic tomorrow morning. A trough of low pressure over the Turks/Caicos NE to a low near 27N/67W will track NE to near 29N/54W by tomorrow morning. This low will strengthen into a gale near 34N/45W by the morning of the 03. A cold front will extend SW from the gale to the north of Puerto Rico on the 03 before lifting NE thru the 04.


Conclusion:


Zone QQ: Persistent trade winds are expected over the next several days with ridging continuing. E-SE shorter period swell will mix with N long period swell thru today, then N-NE swell will take over and build on the 02/03.


Zone RR: E across this zone will become more E-SE and decrease tomorrow and thru much of the 03 thanks to the aforementioned trough/front. Shorter period E-SE swell will mix with long period NE sets by the 03.
