ARC Europe Weather Bermuda-Azores 23 May 2018

Synopsis: High near 32N/47W extends broad ridging NE to Azores, SE to Canaries, and SW to Bahamas. The center will shift NE over the Azores and then change little thru the 28th.

A cold front extends SW to along 35N from Low located near 47N/30W. Will move E over the Azores thru tomorrow morning, weakening to dissipate tomorrow afternoon.

A cut-off Low near 37N/17W will drift SE to near 33N/13W by tomorrow morning. The low will weaken into a trough and then persist thru the 25th.

A Low will strengthen into a gale near 43N/54W tomorrow morning while extending a cold front SW to the US coast (Outer banks). The gale will lift NE to S'rn Greenland by the morning of 26th, while the cold front extends SW to near 35N/45W. The front will then quickly weaken thru the 27th.

An additional gale will be centered near 53N/37W by evening of 27th, while extending a cold front SW along 40N. The gale will lift NE to near 62N/33W by evening of 28th, while the associated cold front extends SW to just west of Azores. The front will overspread the Azores by the morning of the 30th while slowly moving E. A Low will develop along this front near 41N/28W by the morning of the 29th, and will slowly lift NE to near 44N/24W thru afternoon of 30th while strengthening to a gale.

Conclusion: generally moderate winds with swell upwards to 6ft will extend across all grids into this afternoon. Winds will slowly fresh and become strong this evening across Grids HH and JJ. These higher winds will slowly shift E into Grids GG and II late 24th into the 25th in advance of the slow-moving cold front. Winds will gust into the 30s to near 40kts across Grids HH and JJ, to near 30kts across Grid LL and mainly into the 20s across Grid GG and II. Grid KK less effected as the cold front weakens considerably by the time it reaches the grid the evening of the 25th. Expected swell will increase across all grids over the next 2-3 days, with the largest increases being across HH and JJ, with swell that is expected to reach as high as 14ft, though these will lower gradually late 25th. Grid LL will also see a significant increase in swell, though will only reach about 10ft and will arrive later. Across Grids GG and II, swell will increase to about 8-9ft on the 25th, though will be largest across the N'rn portions of Grid GG.
