ARC Europe Weather Bermuda-Azores 21 May 2018



Bermuda to Azores
Prepared May 21 06:16UTC


Synopsis: Broad High near 37N/41W extends moderately strong ridging E to Azores, and SE to Canary Islands, while also extending strong ridging SW from to Bahamas. The high and associated ridging will tend to change little thru the 25th.

A cold front currently extends from N Ireland, SW to Azores. The front will tend to weaken thru 22nd though will make slow, E progression thru this time before dissipating.

A quickly developing gale currently centered in the W'rn Labrador Sea extends a cold front across Nova Scotia, and further SW to the Delmarva region. The front will tend to move E while the gale lifts NE to 61N/37W thru the 23rd. The gale and cold front will both weaken thru the 24th.

A Low will be centered near 43N/54W while extending a cold front SW to the Carolina coast by the 24th. Will strengthen into a gale while lifting NE to S'rn Greenland thru 26th. The associated cold front will then extend SW to near 30N/55W thru the 26th.

A thermal trough of low pressure currently extends between 38N to 43N and between 10W to 20W. Will strengthen into a Low thru late this morning into afternoon across this region. The low will drift SE to near 34N/15W thru the 23rd, before weakening thru the 25th.

Conclusion: Relatively benign conditions across Zones CC, EE, and GG. Expect peak NW swell sets of 4-7 feet across Zone CC, and 5-8 feet across Zones EE and GG. Generally moderate S to SW breezes will prevail across all 3 of these grids as well thru the next 2-3 days.

Across Zones DD, FF, and HH, expect freshening SW breezes thru the evening of 23rd into the 24th with numerous showers and squalls thru late on the 23rd. Peak seas/swells are expected to remain moderate in period across all zones.
