Yellow weather warning for thunderstorms in Hull with possible flooding from downpours

The first day of September is down to be a disrupted one, with a Met Office yellow warning for thunderstorms in the Hull and East Yorkshire area.

The warning is in place from 4am on Sunday, September 1, and continues until 9pm. The area included in the warning covers Hull and also Beverley and Driffield to the north, and west to Goole and beyond.

The Met Office said: “There is a small chance of flooding and disruption from heavy showers and thunderstorms on Sunday in a few places.” A yellow thunderstorm warning alerts people to expect spray and sudden flooding, leading to difficult driving conditions and some road closures.

Where flooding or lightning strikes do occur, there is a chance of delays and some cancellations to train and bus services; there is also a slight chance that power cuts could occur and other services to some homes and businesses could be lost.

During such a weather warning, 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. The overall warning area for tomorrow includes a large swathe of the country, reaching from north of Newcastle to Portsmouth on the south coast.

Many places may miss the thunderstorms altogether but, where they do develop within this warning area, 30mm to 40mm of rain may fall in less than an hour with perhaps over 75mm in one or two places, leading to a chance of flooding and disruption. Dan Harris, Met Office deputy chief meteorologist, said: “Through Saturday night and into Sunday we’ll see a gradual change in our weather across the UK with an increasing chance of heavy thundery showers developing, particularly across central parts of the UK.

“Should they develop there is the risk of some local disruption from intense rainfall, gusty winds, lightning and possibly hail too. Not everywhere within the warning area will see thunderstorms, and confidence in any individual location being affected remains extremely low at this time.

“The risk of thunderstorms steadily transfers northwards through Sunday afternoon and into the early evening. If you have plans for Sunday, I’d recommend keeping up to date with the Met Office forecast and any updates to the warnings.”

Sunday in Hull is down for temperatures of between 15C in the early hours, reaching highs of 20C later in the afternoon. Monday is forecast to be cloudy with a maximum temperature of 22C.
