Preston is expected to see a burst of heavy rain from Tuesday morning onwards.Advertisement
Weather forecasters at the Met Office have issued a yellow warning, their lowest level, for between 50-100mm of rain in a 24 hour period.
The risk of river and localised flooding is also highlighted although the Environment Agency have not issued any flood alerts or warnings at this stage.
The chief forecaster states: “An active cold front is expected to become slow-moving across Wales, north-west England and south and west Scotland through Tuesday, and into Wednesday, before clearing to the south on Wednesday afternoon.
“Warm air of tropical origins is expected to be entrained into the system, leading to abundant moisture and heavy rain. Many parts of the warning area could see 50-100 mm of rain, whilst the most exposed upland parts of north Wales, north-west England and south-west Scotland could see 150-200 mm. As such, there is the potential for river flooding, and also standing water on roads. Strong and gusty south-west winds will also develop.
“There remains some uncertainty with the exact location of the areas at risk of heaviest rain, and as such, this warning will be updated in the coming days as confidence increases.”
