Get your big coat on.

A yellow weather warning for thunderstorms has been issued across Greater Manchester for this week, with some disruption expected.
Nothing says the start of the ‘ber months’ quite like a heavy downpour and some thunderstorms, right? September is here and the summer seems to be long gone, as the Met Office has now issued a series of yellow weather warnings across the UK – including a thunderstorms warning for Greater Manchester and much of the north west.
The Met Office‘s website states that an area of ‘heavy showers and thunderstorms’ is expected, and that this may even cause some localised flooding.
“We’re expecting a band of heavy rain and strong winds to move northeast, followed by heavy showers and the risk of thunderstorms,” commented Rebekah Hicks, who is a Chief Meteorologist at the Met Office.
She explained that as showers progress north-eastward, they will become ‘temporarily slow-moving’, which will lead to an increased chance of surface water flooding.

While the vast majority of places will have ‘non-impactful’ rain, a few places within the North West could see 30-60mm in an hour.
Hail and lightning will also be additional, as will possibly-locally impactful hazards.
Northern residents are being told to expect difficult driving conditions and some road closures, and where any flooding or lightning strikes should occur, there is also a chance of delays and some cancellations to train and bus services.
There’s also a slight chance that power cuts could occur, and other services to some homes and businesses could be lost.
On top of all that, the Met Office says there is a ‘small chance’ that some homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail, or strong winds – although this is expected to be unlikely.
As Friday, southern areas will begin to see more settled conditions, but unfortunately, it’s a different story for the north.
Here in the North West, it will remain wet and windy for much of the day and weekend.
