In the UK, the Met Office – the UK's official weather service – issues weather warnings to let the public, businesses, emergency responders and governments know about severe weather conditions and what the impacts of that weather may be.
These warnings are categorised into three levels – yellow, amber and red – based on the potential impact and likelihood of these impacts occurring.
Here, we take a quick look at what the different colours mean.
Weather warnings: what do the colours mean?
What does a yellow weather warning mean?
A yellow warning is often issued when it is likely that the weather will cause some low-level impacts. A yellow warning could also signify that the weather could bring severe impacts but the certainty of those impacts occurring is low.
When a yellow warning is issued, the Met Office advises the public to remain aware and take precautions if necessary. While the impact may be limited, it can still cause travel disruptions, delays and localised issues such as flooding or strong winds.
Yellow warnings are the most frequently issued and serve as an early alert for worsening conditions.
What does an amber weather warning mean?
An amber warning indicates a higher likelihood of severe weather causing disruption. This level suggests a potential risk to life, as well as damage to property, travel delays, road closures and power outages.
If an amber warning is issued, the public is advised to be prepared and consider adjusting travel plans or taking protective measures. Emergency services and authorities may be on standby for significant impacts.
What does a red weather warning mean?
A red warning is the highest level, meaning dangerous weather conditions are expected and immediate action is required. Widespread disruption, risk to life and major damage to infrastructure are likely. People are advised to stay indoors, avoid travel and follow emergency advice.
These warnings are rare but are issued for extreme events such as storms, blizzards or heatwaves.
The Met Office regularly updates weather warnings based on real-time data, ensuring the public and authorities can prepare for potential hazards. Always check official sources for the latest updates.
