Safety information

What to do under a weather warning

A warning says what weather to expect, what it may do and how sure the forecasters are. Three things first, then what to do before, during and after. From the UK Met Office’s guide to weather warnings and Ready.gov (FEMA).

For this reportSevere Weather · Calais

  1. Read the warning, not only its colour

    It says which weather, where, what it may do and how likely that is. The colour is the summary, not the whole message.

    Met Office
  2. Orange or red: change your plans

    Orange, or amber, means the impacts are more likely: think again about travelling and protect yourself and your home. Red means dangerous weather is expected: act now, avoid travel, follow the emergency services.

    Met Office
  3. Stay informed until it ends

    Warnings are updated, raised and extended. Keep following your national weather service and the local news.

    Met Office · Ready.gov

Before, during, after. Here it is “after”.

Before · Before the weather arrives

  • Get the warnings

    From your national weather service: its app, its website or alerts on your phone.

  • Be ready for a power cut

    A torch, batteries and a charged phone.

  • Think of the people near you

    Older neighbours, people who live alone, anyone who would struggle without roads or power.

Met Office · Ready.gov (FEMA)

During · While the warning is in force

  • Avoid travel if you can

    Above all under an orange or red warning: roads and railways may close.

  • Follow the authorities

    And the emergency services, who know the local situation.

Met Office

After · When the warning ends

  • Mind the damage

    Keep away from fallen power lines and damaged buildings.

Ready.gov (FEMA)
