The Met Office has issued an updated yellow weather warning for thunderstorms across North West England, with the alert now extending to include Greater Manchester. The warning, which was initially in place for parts of the region, highlights the potential for significant weather disruption from Tuesday afternoon into the evening.
Forecasters anticipate that the affected areas could experience heavy downpours, frequent lightning, and strong gusty winds. While specific rainfall totals will vary, localised areas could see substantial accumulations in a short period, raising the risk of surface water flooding. Temperatures in Greater Manchester are expected to remain around 18-20°C before the storms arrive, with wind speeds generally light, but gusts could reach 30-40 mph during thunderstorms.
For the broader North West, including Cumbria, Lancashire, and Cheshire, the warning remains active. Other regions of the UK are not currently under the same severe thunderstorm alert, though scattered showers are possible elsewhere. In Scotland, Wales, and Northern Ireland, the forecast suggests a mix of sunshine and showers, with temperatures generally in the mid-to-high teens Celsius.
The Met Office advises residents in the warning areas to be prepared for potential impacts. These could include difficult driving conditions due to sudden heavy rain and spray, localised flooding of homes and businesses, and possible power cuts. There is also a small chance of damage to buildings from lightning strikes or strong winds. People are encouraged to check local flood alerts and ensure drains are clear where possible.
Practical safety advice includes avoiding unnecessary travel during the peak of the storms, staying indoors, and refraining from using electrical equipment connected to the mains during a lightning strike. If driving, motorists should slow down, use headlights, and be aware of potential standing water. Never attempt to drive through floodwater, as depths can be deceptive.
