Synopsis: A strong upper level low pressure area near 36N/16W later on the 5/12 will move S to the canaries thru the 5/12 while dissipating. Behind this, strong high pressure ridging will build E over mid-ocean with center near 45N/30W by the morning of the 5/12 this ridging will slowly move E with center near 40N/25W by the 8/12. A storm well north with center off of Iceland will move e towards NW Ireland while weakening thru the 5/12. A piece of the storm will move SE along Portugal on the 6/12, then move W over mid-ocean along a weak trough of low pressure. A low will develop west of the high pressure, with center near 37N/52W by the 7/12. Low will move NE to near 50N/35W by the 8/12. Otherwise, broad, weak high pressure ridging over S north Atlantic from 10n to 30N and from 20w to 60W will remain in place thru the 10/12. Conclusion: Swells will be highest in N areas of grid AA thru the 06/12. Swells will slowly build from N grids to S grids over the next several days due to aforementioned trough of low pressure. Swells will be higher in N half of grids BB, CC, DD, EE, FF on the 6/12. Swells will gradually build in grids GG, HH, II, JJ, KK on the 8/12, with higher swells building on the 9/12 in grids NN, OO, PP, QQ. Winds will also freshen from N grids to S grids, starting on the 6/12, with freshening winds in grids BB, CC, DD, EE, FF. Winds will freshen on the 7/12 in grids GG, GG, II, JJ, KK. Winds will freshen in grids NN, OO, PP, QQ on 09/12. T = 4/12 0600 UTC SHWRS/SQUALLS*IN ALL GRID AREAS AA:
