Flintshire has been placed under a Met Office yellow weather warning this weekend, with forecasters warning of heavy rain, strong winds and possible disruption.

The alert is in force from 9am on Saturday 20 September until 6am on Sunday 21 September, covering much of Wales and northern England.

The Met Office says 20–40mm of rain is expected widely, with some locations possibly seeing 60–100mm within just a few hours. Strong gusts of wind, thunder and lightning are also possible during the downpours.

Met Office Deputy Chief Meteorologist Tom Crabtree said: “Through this period 20–40 mm of rain is expected to fall widely, with some locations perhaps seeing 60–100 mm, with much of this total falling in just a few hours. From mid-Saturday onwards, increasingly strong gusty winds and perhaps some thunder will also accompany the rainfall, further increasing the risk of disruption.”

Residents are warned of a small chance of flooding to homes and businesses, power cuts, and delays to road, rail and bus services. Driving conditions could become difficult with spray, standing water and the risk of road closures.

The unsettled spell follows a period of unusually warm weather in parts of the UK, with temperatures reaching 26–27°C in the south of England. Cooler air will sweep in from the north by Sunday, with snow even possible on the highest mountain peaks of Scotland.

For Flintshire, the heaviest rain is expected through Saturday afternoon and evening before easing overnight into Sunday.
