Overview

• Deputy chief meteorologist Tom Crabtree says a deepening North Atlantic low could bring impactful weather most likely on Sunday into Monday.
• The Met Office has not named the system and says it remains too early to confirm precise timing or severity.
• Model guidance suggests widespread heavy rain and strong winds, with the north of the UK most at risk and Irish Sea coasts seeing the strongest gusts.
• Reports indicate gusts could exceed 50 mph with torrential downpours, thunderstorms and hail in places, raising a risk of localised flooding after the wettest week in seven months.
• Temperatures are set to drop sharply, and some forecasters flag a chance of a light snowfall on higher ground such as the Scottish Highlands.
