MetO is currently predicting gusts of 81mph fot St. Ives @ 19:00
http://www.metoffice.gov.uk/weather/...t_weather.html , hopefully that's a slight overestimate, but worth watching.
Recent gust of 65 knots at St. Ives, so that forecast looks like being close.
Also 70mph at Land's End
I don't think I've ever known calm to gale force conditions happen so quickly.
Gusting 45-50mph currently here in Penzance where the wind's offshore, but still tending to increase. I've already seen small branches come off the trees across the stream from me. Strongest winds in May here since at least 2004.
