Overview
- The Met Office extended amber extreme-heat warnings in parts of England after a provisional June high of 37.3°C was recorded at Santon Downham and forecasters say another UK surge is possible in early July.
- Multiple European countries set new temperature records this weekend, including a provisional 41.5°C reading in Drewitz, Germany, and all-time highs in the Czech Republic and Denmark.
- France's national health agency reported about 1,000 more deaths than usual since June 24 linked to the exceptional heat and international agencies estimate well over 150 million Europeans faced temperatures above 35°C over the weekend.
- Violent thunderstorms that followed the heat produced lightning, giant hail, flash floods, storm deaths and major travel disruption with thousands of flights delayed or cancelled at airports including Gatwick and Heathrow.
- U.S. forecasters warn a separate heat dome will build toward the July 4 weekend, bringing widespread highs in the 90s to triple digits and heat-index values that could reach 100–115°F, increasing risks for people without cooling and straining services and infrastructure.
