A moderate rainfall warning, typically issued as a Met Office yellow alert, means heavy rain is likely to cause some disruption such as localised flooding, travel delays and tricky driving conditions – but it is less severe than an amber or red warning.
What does a moderate rainfall warning mean?
When the Met Office issues a moderate rainfall warning (often a yellow warning), it expects prolonged or heavy rain that could affect parts of the UK. For example, a storm to hit Britain this weekend might bring 30–50mm of rain in a few hours. You may see spray on roads, bus or train cancellations, and some homes or businesses could face minor flooding. Unlike an amber warning, which indicates higher impact, a moderate warning means you should stay aware, not alarmed. The moderate rainfall warning map shows which regions are at risk, and the alert can cover anywhere from southern England to weather warning Scotland areas.
