A 10-second siren is set to blare out of mobile phones across the UK as the Government carries out another test of its emergency alert system. The loud alarm was first tested in 2023, and is considered part of a "crucial public safety trial" aimed at preparing people living in the country for life-threatening situations.
This includes severe weather or national security threats. It is designed to inform the public about imminent dangers in their vicinity.
The emergency alert system will once again send a message that reads: "Severe Alert. This is a test of emergency alerts, a new UK government service that will warn you if there's a life-threatening emergency nearby.
"In a real emergency, follow the instructions in the alert to keep yourself and others safe.
"Visit gov.uk/alerts for more information. This is a test. You do not need to take any action."
The last time people in Wales received an alert was for Storm Darragh after the Met Office issued a rare red warning. Read more about that here

What is an emergency alert?
The emergency alert system is used by the Government in areas when there is a potential threat to life such as a red weather warning. It contains information about the threat and provides guidance on how to stay safe.
The system was tested across the UK in April 2023 and this was the largest use of the system outside a test scenario. Every compatible phone receiving the alert made a siren-like sound, much louder than a normal text message, even if they were on silent.
When is it happening?
As global tensions rise and concerns over international instability grow, including the potential for conflict in the Middle East following disturbances in Iran, this year's test underscores the Government's call for heightened readiness among the British public.
The last time the alert sounded, people discussed how loud it was, and how it scared them when it sounded. Some described it as 'Dalek like'.
The exact date of the alert is yet to be announced, but once the next nationwide trial is completed, officials say the system will be activated every two years to keep people ready for emergencies.
Elsewhere, the European Union issued advice to nearly 450 million people to stockpile emergency supplies in case of war, cyber-attacks, natural disasters or pandemics.
The guidance included recommendations to store bottled water, high-energy snacks, torches and waterproof ID pouches, all intended to help families survive up to 72 hours without assistance.
In addition, the EU is planning a crisis handbook to help residents prepare for "various crises, from potential conflict to climate disasters, pandemics and cyber threats," according to The Metro.

In the UK in 2023, some devices failed to receive the notification, prompting questions about the system's reliability.

Monday set to be one of the hottest June days ever with temperatures to hit 34C
Monday is set to be one of the hottest June days on record, with highs of 34C serving tennis fans a sweltering start to Wimbledon. Much of England will enter a fourth day of a heatwave, forecast to be hotter than holiday spots in Barbados, Jamaica and Mexico. Since 1960, UK temperatures in June have surpassed 34C in only three years, with the hottest being 35.6C, recorded on June 28 1976. Here is the 4cast for Monday 📅 Hot across southeast England in particular with temperatures reaching 34 Celsius 🌡️ — Met Office (@metoffice) June 29, 2025 Wimbledon is set for its hottest opening day ever on Monday, with temperatures expected to surpass the previous record of 29.3C set on June 25 2001. The hottest day the tournament has seen was on July 1 2015 when temperatures reached 35.7C. A tropical night may also be on the cards, with parts of England to stay above 20C overnight into Tuesday, the Met Office said. Parts of south-east England could then hit 35C on Tuesday. But, Scotland and Northern Ireland face heavy rain and cooler temperatures. Charlwood in Surrey recorded the hottest temperature of the year so far at 33.2C on June 21. Where is the heat building and how long will it last? The week ahead video below tells all and more 👇 — Met Office (@metoffice) June 29, 2025 A second amber heat health alert in two weeks came into force on Friday. The alert, which covers London, the East Midlands, the South East, the South West and the East of England, will last until 6pm on Tuesday. The UK Health Security Agency (UKHSA) also issued a yellow alert for Yorkshire and Humber and the West Midlands for the same time period, warning of significant impacts on health and social care services. An amber alert was previously issued for all regions in England on June 19, the first time it had been used since September 2023. An official heatwave is recorded when areas reach a certain temperature for three consecutive days, with thresholds varying from 25C to 28C in different parts of the UK. London Fire Brigade assistant commissioner Thomas Goodall said: 'London is already facing its second heatwave of the year and we know that people will be looking forward to getting outside to enjoy the wonderful weather. 'But the high temperatures and low rainfall in recent months means the current risk of wildfires is severe. 'So far this year, firefighters have responded to around 14 wildfires in the capital. 'There have also been countless callouts to smaller fires involving grass, trees and in other outdoor spaces, as well as in people's gardens. 'During this latest heatwave, it is important everyone acts responsibly to prevent fires from occurring. 'As the weather has been so dry, it only takes a few sparks to lead to a fire spreading rapidly. 'In London, this is can be dangerous because so many of our green spaces lie close to homes and other properties.'
