ARC Europe Weather Bermuda-Azores 29 May 2018



Weather: Bermuda to Azores
Prepared: May 29 04:27UTC


Synopsis: A cold front extends along 23W between 45N /65N, then SW just past Azores to 33N/40W. This front is in association with a gale centered offshore of S'rn Greenland that will weaken considerably as it drifts NE . The front will weaken and dissipate shortly after passing 20W.

Moderate ridging extends E to near 10W, with broader ridging continuing E to Gibraltar from High centered S of Azores near 35N. Will drift S-SW to 30N/30W thru 30th, then stalling in the area thru the 03rd, as the ridge axis broadens.

By evening of 30th, a second cold front will extend from 50N/40W S to 40N, then SW 30N/55W in association with a large gale centered near the SE'rn coast of Newfoundland. The front will stall as it extends along 40W on 02nd as the gale center meanders about 40N/50W, while weakening slightly.

A Low expected near 44N/25W by midday of 01st. Will weaken slightly as it moves ESE over Iberia on 02nd.

Conclusion: We are continuing to watch a cold front as it crosses the forecast area over the next 24-36 hours as well as a second cold front will remain to the west of the forecast area, though will provide enhanced SW on the 31st and 01st. The strongest SW winds will be seen across Grid NN, with moderate to freshening winds expected. More moderate SW winds will be seen across Grids MM, OO and PP. These winds will gust into the lower and middle 20s across Grid NN throughout much of the 30th, though will increase into the upper 20s on the 31st with the second cold front to the west. Throughout the other grids, winds gusts are expected to remain within 20kts. The largest swell will be found across Grids NN and PP, with swell mainly up to 8ft at times throughout the forecast period, with a few 9ft swell sets expected late 31st across Grid NN. Across the S'rn Grids MM and OO, swell will increase gradually throughout the next 1-2 days, with swell up to 7ft expected throughout the forecast period.
