A moderate rainfall warning is a Met Office yellow alert indicating rain that could cause localised flooding and travel disruption. It means stay aware, not alarmed: check forecasts for your area and allow extra time for journeys.
What does a moderate rainfall warning mean?
This is the Met Office’s lowest warning tier, usually issued when rain totals of 15–25 mm per hour are expected over several hours. Unlike an amber weather warning, which signals a higher likelihood of significant impacts, a moderate (yellow) warning asks you to be mindful of possible spray on roads, standing water, and minor delays. The UK weather hub provides the latest updates.
Where and when is the warning in effect?
Warnings are most common in western and northern parts of the UK, particularly Scotland and northern England. A moderate rainfall warning today may cover a broad area or a specific region such as London or the Scottish borders. The Met Office publishes a moderate rainfall warning map showing exact zones and timing. While this warning is not linked to a named storm, forecasters note that a storm to hit Britain this weekend could bring additional heavy rain in some areas.
Is a moderate rainfall warning dangerous?
For most people, no. However, heavy rain can reduce visibility and increase stopping distances. Flooding of low-lying roads and underpasses is possible, so avoid driving through floodwater.
Should I cancel travel plans?
Not necessarily, but allow extra time. Check local transport updates and the 10-day weather forecast for your route. If you’re in an area prone to flash flooding, consider postponing non-essential journeys.
What is the difference between yellow and amber rain warnings?
A yellow warning means “be aware” of possible disruption; an amber warning means “be prepared” for more severe impacts such as widespread flooding and significant travel delays. The Met Office escalates to amber when confidence in impacts is high.
