Around 10 countries are preparing for extreme temperatures as a powerful heat dome settles over parts of Europe and the Mediterranean. The persistent high-pressure system is expected to trap hot air, driving temperatures well above seasonal averages and increasing the risk of wildfires, drought and heat-related illnesses.
What Is a Heat Dome?
A heat dome is a weather pattern in which a strong high-pressure system traps hot air near the ground. Clear skies and sinking air allow temperatures to build over several days.
Countries on Alert
Authorities in multiple countries have issued heat advisories, urging residents to limit outdoor activity during peak afternoon hours and remain hydrated.
Health Risks
Extreme heat can lead to dehydration, heat exhaustion and heatstroke, particularly among children, older adults and people with chronic illnesses.
Safety Tips
Drink plenty of water, wear light clothing, stay in cool places, avoid prolonged sun exposure and check on vulnerable family members and neighbours.
The Bottom Line
Officials are urging residents and travellers to follow weather updates and heat safety guidance until the heat dome weakens.
