NOAA NWW3 still going for 12m east-going waves in the Channel Approaches
is roughly consistent with that.


If you look here https://magicseaweed.com/UK-Ireland-...1/?type=period
(make sure the period option is chosen) although the swell isn't forecast to be that big for SW England (around 15' near Lands End /Sennen) it's pretty long period as it arrives around 3am Tuesday, so could be quite powerful.

With an offshore S-SW wind forecast for the north coast of Cornwall on Tuesday, the surf should be great, combined with some warm sunshine.

Assuming the models are right of course - it's still 4 days away.

Although the latest projected tracks for Helene are more to the west,
the same multi-model TS-specific models suggest no weakening and
lowering central pressure out to UK passage time.
An outlier for Joyce has one track for the Eng Channel about the same
time, compared to Iberia for the majority.

MetO has the central pressure for Helene rising ,before and during its
passage over UK+Eire. But 5 of 5 of the tropical storm specific models
have the central pressure dropping during that time?
