A rain area is expected to develop in eastern and central England before moving northwestward to impact northern England and north Wales on Wednesday afternoon. The rain could become heavy and persistent, particularly over north-facing hills, before clearing on Thursday morning.
There is uncertainty regarding where the heaviest rain will fall, so this warning may be revised. Most areas could see 30-40 mm of rain, with some areas potentially receiving 60-80 mm. There is a slight chance of upland areas experiencing even higher totals, around 100-150 mm.
To prepare for potential flooding, assess if your property is at risk and create a flood plan and emergency kit. Check road conditions and transportation schedules for possible delays and adjust your travel plans accordingly. Be ready for power outages by gathering essential items like torches, batteries, and a mobile phone power pack. Stay informed about weather warnings as they can change rapidly. The Met Office advises keeping up with local weather forecasts.
