OP says 80-90mph? Is that suppose to be kph? Is it normal for Britain to still use imperial measurements for wind? I'm from the States so I have no idea.
Nah it's mph; sometime in the 1970's a law was passed whereby two-eighths of all measurements would become metric, three-eighths would remain imperial, and the remainder would be randomly assigned imperial or metric based on the outcome of a horse race.
That of course isn't true, but we do have stupid situations like: fuel is measured and sold in litres, but fuel consumption is exclusively calculated in miles-per-gallon. Beer is measured in pints, but wine is measured in litres (or centilitres). When the temperature is hot, the weather reports drop in references to Fahrenheit to exaggerate the high number (despite being
displayed in celsius which is the standard), but when it's cold they'll only mention celsius.
The best one though, is road signs. I'm not sure if this applies to permanent signs, but for roadworks, there is usually a series of signs stating that there are roadworks in '800 yards', then '400 yards', then 200. These are
not actually yards; they actually mean 800 metres, 400 metres, and 200 metres. Legally they need to show yards to drivers, but the actual road network and construction is all done in metres/kilometres. They make 1 yard = 1 metre for the sake of these signs; they're similar, but the different is pretty big by the time you're at 800.
EDIT: Also, I'm right in the middle of that red zone, just north-west of London. We've already had some flash flooding around here but I'm off work on Monday so I'll purely be a spectator for all this. Getting to work would be troublesome as I suspect they'll put a 50 speed limit on the trains.
