A moderate rainfall warning is a Met Office alert indicating that rain is expected to cause some disruption, such as localised flooding or travel delays, but is not severe enough to pose a widespread danger to life or property.

What does a moderate rainfall warning mean for you?

This warning, often colour-coded yellow, means you should plan ahead rather than cancel plans. Check your local forecast for the timing of the heaviest rain, especially if you are driving or live in an area prone to surface water flooding. The key takeaway is to allow extra travel time and secure any loose outdoor items.

How does this compare to other warnings?

Moderate rainfall warnings are less severe than amber or red warnings. An amber warning means there is a higher likelihood of significant disruption, while a red warning signals extreme weather with a danger to life. A moderate warning is a heads-up, not a panic signal. For context on the most severe alerts, see our guide on Storm Amy Weather Warnings.

Is a moderate rainfall warning the same as a storm warning?

No. A storm warning typically involves strong winds and heavy rain together. A moderate rainfall warning focuses solely on rain, though it can be issued during a named storm like Storm Floris.

Should I drive during a moderate rainfall warning?

Yes, but with caution. Reduce your speed, increase your following distance, and avoid driving through standing water. Check for weather warning Scotland updates if you are travelling north.

Where can I see a moderate rainfall warning map?

The Met Office provides an interactive warning map on its website. You can also view regional details for areas like moderate rainfall warning London on our UK weather hub.
