Weather USA-Bermuda 7 May



Wearher Portsmouth VA to Bermuda
07 May 2018

Prepared: May 07 08:14UTC

Synopsis: A broad High centered near 32N/52W extends stronger ridging SW to BVI/Puerto Rico, while extending broad ridging E to the Azores and SE to the Canaries. The high center will tend to remain broad thru the 11th, while the center shifts NE to near 42N/37W.

A Low centered near 37N/70W currently extends a cold front SW thru Bermuda/Bahamas/Florida. Will accelerate NE into the W'rn Labrador Sea by tomorrow evening, while a cold front slowly moves E and extends across Bermuda, the S'rn Bahamas/T&C. The front will continue to change little thru the 10th while then gradually weakening thru the 11th. The Low will strengthen into a gale/storm by the morning of 9th and will be located near 55N/22W. The storm will then extend another cold front SW to the Azores and along 40N thru this time. The front will weaken over the Azores by the morning of the 10th.

A Low will extend across the far W'rn Labrador Sea by tomorrow evening, while extending a cold front SW across New York State. The low will strengthen into a gale by the morning of 11th as it quickly lifts NE to near 57N/24W. Will then extend a cold front SW across the Azores by morning of the 11th. The front will weaken as the gale remains centered near 56N/20W thru the morning of 12th.

Conclusion: As a cold front passes to the east of Zone I, breezes will shift NE this morning and remain NE thru at least the morning of 09th. NE winds will continue to be enhanced over the next 2-3 days. Additionally, moderate period, SE to NE swell sets will peak between 7-10 feet this morning while gradually abating as the remnants of Tropical Low 1 continue to move NE and away from the region.

Conditions will be more unsettled across Zone F today, as the front traverses thru this grid during the day. Fresh to strong SE gusts will prevail this morning and remain generally SE while easing thru the morning of 09th. The interaction of the strong cold front associated with the remnants of Tropical Low 1 will yield these enhanced conditions. However, because of the prevalent ridging, the front will be slow to move E'ward over the next 2-3 days. Peak S swell sets between 13-16 feet will be expected this morning while lowering thru this afternoon and evening.
