Storm Bert weather maps show hour-by-hour forecast for North Wales as torrential rain to hit

The forecast for today is not good reading for North Wales as Storm Bert is set to hit the UK. The storm will bring heavy rain to Wales and much of England and snow in the north of England and Scotland.

This will be alongside strong winds with warnings of flooding in North Wales as rain mixes with the melting snow. Peak gusts of 50-60mph are expected but this could reach 70mph in coastal areas of Anglesey and Gwynedd.

In North Wales the heavy rain will start at around 5am and continue until 6pm with the potential of in excess of 100mm possible.

Met Office Deputy Chief Meteorologist Dan Holley said: “Storm Bert marks a shift to much milder air and wintry hazards will gradually diminish through the weekend, but heavy snowfall is expected across parts of northern England and Scotland for a time on Saturday, especially over higher ground, and warnings are in place.

“Heavy rain through Saturday and Sunday, especially in southern and western parts of the UK, will also bring impacts for some with a number of warnings in place. We expect 50-75 mm of rainfall quite widely within the warning areas, but in excess of 100 mm is possible over high ground in parts of Wales and southwest England.

“In addition, rapid melting of lying snow over the weekend and periods of strong winds are likely to exacerbate impacts and bring the potential for travel disruption, as well as flooding for some.”

Here are the hour-by-hour weather maps for North Wales as the storm hits.
