Further details

Storm Betty is expected to bring a swathe of very strong and gusty winds to the Isles of Scilly early Friday evening, quickly transferring north across many western parts of the UK overnight and into Saturday morning. Strongest winds will be along south to southwest facing coasts where gusts of 60-70 mph are possible, whilst gusts of 45-55 mph are possible elsewhere. Given the time of year, with trees in full leaf, as well as likely temporary structures such as tents and marquees, some disruption is likely. Impacts on high-sided vehicles and caravans are also likely.
