A fierce northwesterly storm is affecting the northwest of Corsica at the moment (fig 1), and there have been gusts in excess of 100 knots since 17 UTC at Cap Corse, with maximum gusts of 122 knots (140 mph) reported at 00,01 & 02 UTC earlier this morning. Mean speeds on the cape have been in excess of 50 knots for the last 24 hours.
From reading the Wikipedia article it appears that Cap Corse is the name for the whole peninsula at the top of Corsica, and that Capo Grosso (I wonder what that translates to?) is the proper location of the SYNOP station WMO #07785. Anyway at first glance the wind speeds look far too high, but they are supported partly by the pressure field, and surrounding observations – perhaps they’ve switched to reporting in knots and I’m still converting then from metres per second?! Here’s a map of Corsican SYNOP stations with Capo Grosso highlighted in yellow (fig 2).
Let’s take a little closer look at the SYNOP station at Capo Grosso with aid of Google maps (fig 3).
Well, there you have it, Capo Grosso seems to be the French equivalent of what our old Needles battery is to us! It looks like the station is perched atop a 370 foot cliff which is open to anything that the Ligurian Sea can throw at it. The northwesterly gradient will no doubt be getting a hand from funneling off the Alps, and the Mistral that’s currently blowing across the south of France and the northwest of Italy (fig 4).
