Understanding Weather Warnings and Flood Alerts

Weather Warnings

The Met Office issues weather warnings when severe weather has the potential to bring impacts to the UK. These warnings are given a colour (yellow, amber, or red) depending on a combination of both the impact the weather may have and the likelihood of those impacts occurring.

It is important to understand what the different weather warnings means so you can understand what to expect when a warning is issued.

Weather Warning

What could be happening?

What should you do?




Yellow warnings can be issued for a range of weather situations. Many are issued when it is likely that the weather will cause some low-level impacts, including some disruption to travel in a few places.

You should check the details of the forecast and consider taking steps to minimise impacts for you and your household.




There is an increased likelihood of impacts from severe weather, which could potentially disrupt your plans. This means there is the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.

Disruption is more likely and more widespread. You should change plans that could be impacted by the weather and take action to protect yourself and your property.





Dangerous weather is expected, and it is very likely that there will be a risk to life, with substantial disruption to travel, energy supplies and possible widespread damage to property and infrastructure.

You should act now to keep yourself and others safe from the impact of the severe weather. You should avoid travelling, where possible, and follow the advice of the emergency services and local authorities.
