Weather Alerts
Icy stretches will develop during Wednesday and evening and Thursday morning.
As areas of rain, sleet and snow gradually clear to the east during Wednesday evening and early Thursday morning and temperatures fall close to or a little below freezing, some ice is likely to develop on untreated surfaces across parts of Wales and western England. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal. Not needing to rush, reduces your risk of accidents, slips, and falls. If you need to make a journey on foot, try to use pavements along main roads which are likely to be less slippery. Similarly, if cycling, try and stick to main roads which are more likely to have been treated. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
