WX ARC PLUS 2017 29 Nov



Synopsis: Good morning. A ridge of high pressure currently extend S across the Bahamas and towards the E Caribbean, and SE towards about 15N/45W. Ridging will tend to weaken thru today, then remain weak thru the 01 . By tomorrow morning, a trough of low pressure will begin to form, extending from the E Caribbean NNE across the Leeward Islands towards about 25N/65W. A weak area of low pressure will develop near this area, drifting E towards 25N/55W thru the 01 , then continuing NE towards about 33N/52W thru the 02 .


Conclusion: Generally moderate E-NE are expected to persist across the zones thru the next few days (fresh at times) with ridging persisting.

Breezes will tend to weaken marginally by the 30/01 as the aforementioned trough develops (while also shifting more E-SE , especially in zone RR). Long period NE swell will mix with some shorter period E-SE sets beginning on the 01 , especially in more S areas along the zones and in zone QQ/RR.
