The Met Office has issued a yellow weather warning for rain across the South West, valid from 06:00 Tuesday to 06:00 Wednesday, with 20–40 mm widely expected and up to 60 mm on higher ground, meaning widespread disruption to travel is possible.
What areas does the warning cover and when is it active?
Devon, Cornwall, Somerset, Dorset and the Isles of Scilly are included in the warning zone, with the heaviest rain expected between late Tuesday morning and Tuesday evening. The yellow warning is for rain only; no separate snow warning or storm warning is currently in place for the region, though saturated ground increases the flood risk locally.
Is this linked to a storm or a broader cold spell?
Unlike a named storm to hit Britain this weekend, this event is a slow-moving frontal system drawing moisture from the Atlantic. There is no met office snow warning active for the South West at this stage, though colder air may arrive late in the week, lowering snow levels on Dartmoor and Exmoor.

What other South West weather warnings are there this week?
As of now, the Met Office has issued only one weather warning today for the region. No additional south west england weather warning for wind or ice is in force, but check our storm tracker for live updates if conditions change. For a longer outlook, refer to the 10 day weather forecast UK or the dedicated moderate rainfall warning page.
Will the South West see any snow from this warning?
This yellow warning is for rain only, not snow. However, if colder air moves in behind the front by Thursday, snow could fall above 250–300 m on Dartmoor and the Mendips; this is not currently covered by any met office snow warning.
How does this compare to the 14-day South West forecast?
The south west weather 14 day forecast suggests a return to drier, more settled conditions by the weekend. The met office 7 day south west weather forecast shows the warning period as the wettest point, with rainfall totals decreasing sharply after Wednesday.
Should I expect flooding tomorrow?
Localised surface water flooding is possible on roads and in low-lying areas, especially in Somerset and Devon where soils are already wet. Check the Environment Agency flood alerts via GOV.UK and avoid driving through standing water.
