Lancaster weather: Met Office thunderstorm warning issued for Lancaster - map shows when heavy rain could hit

A Met Office thunderstorm warning has been issued for Lancaster.

The yellow thunderstorm warning will be in place from 17:00 on June 21 to 03:00 on June 22.

The warning reads: “Thunderstorms may cause some impacts in places on Saturday evening and night.

“There is a small chance that some communities become cut off by flooded roads. There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost. Spray and sudden flooding could lead to difficult driving conditions and some temporary road closures. There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds. Where lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.

“Whilst some showers and isolated thunderstorms are expected during Saturday afternoon, further and potentially intense thunderstorms are likely to develop during Saturday evening across northwest England and perhaps northeast Wales. Whilst there is still some uncertainty in when and where these develop, thunderstorms could produce a combination of frequent lightning, large hail, strong winds and heavy rain (in places, 30-40 mm in less than 2 hours) as they move northeast into northeast England and perhaps southeast Scotland overnight. Thunderstorms are expected to move offshore into the North Sea during the latter part of Saturday night.“
