"Exposed areas in Scotland, Northern Ireland, parts of Wales and northern England have seen wind speeds largely between 60 and 70mph but the worst affected areas have reached and even surpassed 80mph this afternoon.
"In terms of rainfall the highest we've seen in the past 24 hours is 36.8mm in Low Laithes in west Yorkshire, which is a good amount for the time period.
