BRITISH weather is known for its unpredictability with glorious sunshine turning into a downpour in a few hours.
And despite the UK not being known for volcanoes, deadly earthquakes or raging tornadoes, we get our fair share of Mother Nature’s fury.
The weather warning system operates 24/7 365 days a year
What is a danger to life weather warning?
The Met Office issues a series of warning over bad weather, known as The Met Office National Severe Weather Warning Service (NSWWS).
These range from very low to high, and as well as general warnings there are also specific warnings for rain, thunderstorms, wind, snow, lightning, ice and fog.
In the general and the specific weather categories, two of the most severe warnings carry a danger to life.
These are medium and high warnings, and in the former the Met Office say these may cause “injuries with danger to life”.
The alerts range from very low, to low, medium and high
In the highest category, it simply states there is a “danger to life”.
When broken down by weather type, for rain and thunderstorms danger to life may occur from flooding.
For wind, it warns of “widespread danger to life from flying debris”, and lightning carries the risk of “injuries with danger to life due to frequent lightning strikes”.
When are they issued?
The Met Office operates 24/7 365 days a year, so a warning can be issued at any time.
The UK’s official weather service, the warnings are designed to “let people, businesses, emergency responders and governments know what weather is in store and what the impacts of that weather may be.”
In order for all concerned parties to be prepared, weather warnings are issued up to seven days in advance to allow time for all necessary precautions to be made.
Rex Features Warnings also cover specific weather events including rain, thunderstorms, wind, snow, lightning, ice and fog
What do they mean?
The weather warnings are also colour coded, with yellow, amber and red alerts.
The Met Office says: “These impacts can include damage to property, travel delays and cancellations, loss of water supplies, power cuts and, in the most severe cases, bring a danger to life.”
A matric is used for people to assess how likely a weather event is, and how serious it is.
The Met Office breaks down the colour codes as follows:
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. Many people may be able to continue with their daily routine, but there will be some that will be directly impacted and so it is important to assess if you could be affected. Other yellow warnings are issued when the weather could bring much more severe impacts to the majority of people but the certainty of those impacts occurring is much lower.

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. You should think about changing your plans and taking action to protect yourself and your property. You may want to consider the impact of the weather on your family and your community and whether there is anything you need to do ahead of the severe weather to minimise the impact.
