Anyone currently in sea area Hebrides?

[DaveS]

Today's shipping forecast is something else, and I'm very glad I'm not at sea.

"Hebrides
Gale warning 0356 Sat 17 Mar
Westerly gale force 8 increasing hurricane force 12 later

Shipping forecast 1130 Sat 17 Mar
Wind Southwest veering northwest 6 to gale 8, becoming cyclonic violent storm 11 or hurricane force 12 for a time.
Weather Rain then wintry showers.
Visibility Moderate occasionally very poor.
Sea State Very rough or high, becoming very high or phenomenal for a time."

Anyone know just how big the waves get when the sea state is "phenomenal"?

A "phenomenal" sea state means a swell or waves greater than 14 metres in height. 14m is the equivalent of 2 modest modern two storey houses, one on top of the other.

I can't imagine anyone wanting to be out in such a sea.

14 metres? Whoa!
I wonder what the wavelength and the frequency is? Then we could tell the average angle of plunge/rise and how many times an hour.
Extremely unpleasant, and I hope there is NO ONE out there.

The MAWS network gives hourly readings of wave heights and wave periods here .

K5 buoy at 59 deg 06 min N, 11 deg 42 min W, shows a wave height of 5.7m and a wave period of 9 seconds at 1500 today. It will be interesting to see what the recorded wave height gets up to later.

And look what the pressure was doing earlier, steadied out now though HERE

Not in Hebrides, but I am out in Forties at the moment, and I can tell you its pretty wild. Wind is steady over 60knots and over 70 knots at times, couldn't tell you the wave height but I wouldn't like to be out on a small boat.
Having said that though, I don't think the waves are anything like 14m, though they look quite large even from 50 feet or so above them. It is nice to experience it without having to worry too much though and looking at the sea state it does look as though a well found yacht should be able to survive it.
The supply vessel couldn't get to us and the water maker is down so water is rationed now. Hoping to get off tomorrow if the wind drops enough for the helicopter to land.
Forgot to say Im about half way to Norway on an oil rig.
