WX ARC PLUS 2017 24 Nov



Synopsis: Good morning. A developing gale south of the Azores will strengthen as it moves E to the west of Madeira near 32N/23W by am/26, then slowly weakening as it moves to the north of Madeira near 37N/17W by am/28 where it will stall and continue to weaken thru the 29.Generally weak ridging currently extends from 35N S towards about 20N, and roughly between 55W to 40W. This ridging will tend to extend SW towards the E Caribbean tomorrow, followed by persisting thru the 26. This same ridging will also expand SE towards the Cape Verde Islands on the 26 and persist thru the 28th.


Conclusion: Conditions will not vary a whole lot across the zones of concern over the next few days as ridging remains generally weak and the aforementioned gale stays well to the NE of the areas. The main differences will be slightly higher and more present long period swell from the previously mentioned gale across the more E zones (mainly OO and PP), and slightly stronger trades winds on the W two zones thanks to being closer to the aforementioned ridge. Otherwise, no heavy weather concerns are expected across any of the zones thru the forecast period.
