There'll then be a brief lull, and it will hit again, probably in the late afternoon. You'll know when it arrives, that's for sure.
As far as London is concerned, the worst weather is likely to come during the morning rush hour, and the Met office says there's a 60% chance of 'disruption', whatever that means. Trees will no doubt fall, but in big cities I think the main risk to people comes from flying debris - roof tiles, signs, that kind of thing.
With luck it won't be as bad as has been predicted, but don't bank on that - my barometer has been fairly steady today, but it's falling very slowly now.
I was planning to go to the new Victoria Square in Belfast tomorrow. Don't think I'll bother now and not much point grocery shopping either barca1's link says Stena cancelled ferrys which means no deliveries to the supermarkets. :(
Yes there will be high winds and lots of rain. It is a gale, a storm for goodness sake, they occur frequently particularly at this time of year. What a kerfuffle. Some dumbo in the Met. Office thinks we should all stay indoors. Sad.
