UKMO playing hardball with Marco

The UKMO have had to extend their yellow wind warning for strong winds to cover more of north Wales. You would think they would have learned by now that the windiest places in situations like are often (a) Aberdaron on the Llyn peninsula and (b) Capel Curig in Snowdonia which I’ve seen happen so many times since I started blogging. They are still playing hardball by keeping the extreme gusts relatively low both on coasts and inland, and have not extended their warning to cover the gusts over East Anglia which the ECMWF model anticipates at 12 UTC. I think if it had been me I would have added 10 mph to both of these ranges.

Reason for update

Warning updated to an earlier start time and to extend it further north into west and north Wales.

An unusually deep area of low pressure for the time of year will move slowly eastwards across a central swathe of the UK during Thursday night and Friday. In addition to some heavy rain, this low will bring with it a spell of relatively high winds. The windiest conditions will start to affect south Wales and southwest England Thursday late afternoon and evening before spreading across southern England Thursday night and early Friday. Inland, gusts up to 45 to 50 mph are expected at times whilst over coasts and hills gusts will reach as much as 55 to 60 mph. These high winds then slowly ease from the west during Friday.
