Overview
- A 24-hour rain warning runs 6pm Monday to 6pm Tuesday for Wales and south-west England, extending into parts of Hampshire and Oxfordshire, with 20–40mm widely, 60–80mm over Dartmoor and south Wales, and a small chance of 80–100mm on exposed hills.
- A concurrent wind warning from 10pm Monday to 4pm Tuesday covers Wales and the south-west, with gusts around 50mph widely and up to about 70mph on exposed coasts and high ground, risking power outages and hazardous coastal conditions.
- Further alerts include a rain warning for northern England from midnight to 3pm Tuesday with 20–40mm over hills and up to 80mm in Cumbria, plus a wind warning for north-west Scotland from 3pm Tuesday to 10am Wednesday with gusts approaching 70mph.
- Forecasters warn of flooding risks including fast flowing or deep water that could endanger life, with saturated ground and existing flood warnings and alerts heightening the threat after a wet weekend that included a Northern Ireland rain warning on Sunday.
- Meteorologists note uncertainty over the low-pressure system’s exact track and depth, so areas of greatest impact could shift and warnings may be updated; local disruption is already occurring, including the cancellation of Plymouth’s Santa Fun Run.
