Frontal Low in the top-left of the image.
In the next 36 hours the low will continue to deepen and in this image the pressure is 955 mb, usually correspondent to a weak Cat. 3 hurricane.

Looks like a major storm for the British Isles and Scandanavia with heavy seas and very high winds. Since this is a cold core system im not sure if it will produce Cat 3 force winds but you can bet on 70-80 mph winds over open waters and coastal areas to the right of the track of this storm center...along with heavy rains.

http://129.13.102.67/pics/bracka.gif - I haven't worked out the PGF on this chart but I'm fairly sure the winds won't be that strong. Looks like it could be breezy in northern Scotland as it passes to the north. http://www.metcheck.com/48hrforecast.asp?lat=60&lon=-1&locationID=52

Yea Sandy I know...I was just mentioning I wasnt sure if the same parameters applied to cold core systems as well. Sorry if my post sounded rude.

Winds in extratropical lows tend to be much lower than in tropical lows. The reason is in tropical lows, the highest winds tend to be closer to the surface. But in extratropical lows, the strongest winds are usually found at higher altitudes.
The lowest barometric pressures in extratropical lows tend to be higher than tropical cyclones. However, that doesn't mean extratropical lows can't have very low pressures. Some extratropical lows have had pressures below 920 mb, which is the threshold for Category 5 hurricanes.
