Headline

Heavy rain falling on saturated ground may lead to some surface water flooding on Thursday

What should I expect?

  • Flooding of a few homes and businesses is possible
  • Bus and train services probably affected with journey times taking longer
  • Spray and flooding on roads probably making journey times longer

Further detail

An area of low pressure will migrate northeastwards across England on Thursday. Whilst the exact track is uncertain, rain will become persistent and heavy through the day, before clearing to the north through the evening and night. Accumulations of 20-30 mm are expected fairly widely, in some places falling in just a few hours, with the potential for 40-50 mm in a few isolated spots. Given the saturated ground, this may lead to some surface water flooding.

What Should I Do?

Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.

Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
