Impressive set of storms for UK&Eire, starting with Helene, then a
cyclogenesis enhanced monster from Canada.
Impressive winds, such that NWW3 06Z run is giving 10m sig wave height
under Helene then and 12m under the "Canadian" low, considering its only
giving 12m under florence tomorrow , prior to Carolinas landfall
Nothing out of the ordinary on Magic Seaweed yet, which is largely GFS based
At least up 'til next Tuesday, after that date is basically guesswork
It does reach 6-9' at Sennen next Tuesday, but it was that sort of height last Monday when the period was longer & therefore the swell was more powerful. (I speak from experience!)
The most powerful swell in the forecast is on Monday when the swell is smaller (5-7') but the period when the swell arrives in 17secs, which makes it powerful, but still nothing out of the ordinary. Could be a great surfing day though.
Time will tell.
Just pleased I'm not in Carolina.
