A further weather warning has been issued for the North West as thunderstorms and rain continue to batter the UK.

Yesterday, the Met Office issued a thunderstorm warning from 4am to 9pm for today (Sunday, September 1).

However, the weather agency has now altered the warning to extend it to midnight tonight.

It is in place across the region, including Bolton, Bury, Lancashire, Oldham and Trafford. 

A further warning has also been issued for the entirety of Monday, September 2, with residents warned that thunderstorms could cause flooding and disruption in places.

The Met Office warns that there could be cancellations to train and bus services as a result of flooding and lightning, and power cuts could occur.

According to the weather agency, Monday’s warning has a ‘very low likelihood and a medium impact’, leading to the yellow warning classification.

Tomorrow’s warning stretches from as far south as London, covering Cardiff, Manchester, Newcastle, and stretching as far north as Aberdeen.

The Met Office says some places may see 30 to 40mm of rain fall in less than an hour, with perhaps more than 60 to 80mm falling in some places – alongside ‘frequent lightning strikes and hail’.

However, the weather agency says many areas ar e expected to miss the thunderstorms, with the extent of the thunderstorms remaining uncertain.

It’s expected that the focus for the thunderstorms and its impacts will gradually move east throughout Monday, the Met Office says.

Those planning to travel on Monday have been advised to check road conditions and bus and train timetables before they set off, amending travel plans if necessary.

Torches, mobile phone power packs, and other electrical essentials should also be gathered and fully charged prior to any potential power cuts.

Those outside who hear thunder should find safe enclosed shelter, such as a car, and should not shelter under or near trees or other structures that may be struck by lightning, the Met Office says, with those on elevated ground advised to move lower down.
