Overview

• A yellow warning for heavy rain runs from 9am Saturday to 6am Sunday, with a slow‑moving band bringing 20–30 mm widely and isolated 60–80 mm bursts that could fall in a few hours.
• Forecasters caution about local flooding, difficult travel and a slight chance of power cuts or building damage, with the AA urging reduced speeds, extra journey time and pre‑trip checks.
• A separate yellow wind warning covers Wales from Saturday afternoon into the early hours of Sunday, with 50–60 mph gusts inland and 65–75 mph possible on exposed coasts.
• Parts of eastern England, including areas of Cambridgeshire, are also under a wind warning overnight, with a small chance of travel disruption, debris and isolated power outages.
• Natural Resources Wales has issued six flood alerts for coastal and north Wales catchments, as rain moves east before cooler air sweeps in and the first frosts of autumn become possible next week.
