A YELLOW weather warning has been issued for rain across the north west.

Rainfall could exceed 50mm in some places, with 20-30mm falling elsewhere, as heavy, slow moving and possibly thundery showers are likely tomorrow, Friday, the Met Office has warned.

The remains of hurricane Bertha are expected to come steadily towards the UK during the next few days but the Met Office has said this is unrelated to the rainfall expected tomorrow.

Craig Woolhouse, Environment Agency flood risk manager, said: "Heavy downpours, some slow-moving, bring a risk of localised surface water flooding to parts of the Midlands, the north west and eastern areas of England on Friday.

"However, the forecast remains uncertain so we advise people to regularly check the flood risk situation over the next 48 hours.

"The Environment Agency is continuing to monitor the situation closely along with the Met Office and local authorities.”

The Met Office has been assessing the likelihood of the UK seeing any effects from Bertha and has said that southern parts of the UK look as though they are most at risk.

However, there is also the possibility that the storm could move across northern France as a weak feature and also a risk of a more intense system affecting the UK more widely.

Chief forecaster at the Met Office, Eddy Carroll, said: “There is still considerable uncertainty surrounding this weekend’s weather, with the potential for heavy rainfall and strong coastal winds, along with large waves.

“However, there is a chance that the system may pass to the south of the country, or spread heavy rain even further north.

“Rain and strong winds may well bring disruption, especially in the south, and people should stay up to date with the latest Met Office warnings.”
