AA urges drivers to prepare for disruption amid yellow weather warnings

  • Yellow weather warning in place for much of England
  • 20-30mm of rain predicted
  • “If driving, slow down, keep your distance, and avoid flooded routes where possible” – AA Patrol of the Year

The AA is urging drivers to take extra care on the roads this weekend as the Met Office issues yellow weather warnings for thunderstorms across much of the UK from Friday evening (18 July) through to Saturday evening (19 July).

The yellow warnings cover large parts of England, with predictions of 20-30mm of rain in less than an hour in many places, with 60-90 mm in less than three hours possible in other areas. This amount of rain is well over a month’s worth for a normal July.

As well as heavy rain, impacts from frequent lightning, gusty winds and large hail are also likely.

These storms could affect some of the popular holiday routes for early departures on this year’s summer getaway.

While localised flash flooding and the sudden appearance of surface water are the usual dangers associated with summer heavy rain, the potential for slippery road surfaces at junctions and roundabouts is a hidden menace.

During hot and dry weather, vehicle tyres deposit rubber on the road at junctions and roundabouts. Rain falling on these surfaces can make them slick and slippery, at least for the first couple of hours.

That can lead to increased stopping distances and the potential for vehicles to slide across the line.

Shaun Jones, AA Patrol of the Year, said: “We’re urging drivers to plan ahead and allow extra time for journeys. Surface water and reduced visibility can make driving hazardous, especially on rural or poorly lit roads. If driving, slow down, keep your distance, and avoid flooded routes where possible.

“Drivers should check their vehicles before setting off, including tyre tread, wiper blades, and screen wash levels.

“Use the AA Route Planner to check where congestion is and plan accordingly. If you can change plans to travel after the warning passes it might be a good idea to.”
