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 · Russia
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 OfficeOrange 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 OfficeStay 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 still “during”.
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.
