Heat Wave Hits US, Canada, and UK

A major early-season heat wave is set to impact California, parts of Canada, and the UK, with several regions under heat advisories and extreme heat watches. In Northern California and the Bay Area, temperatures may reach up to 109°F, with limited overnight relief increasing risks of heat-related illnesses and fire danger. Environment Canada has issued heat warnings for most of Alberta, where temperatures are expected to meet or exceed 29°C, ongoing wildfires have triggered evacuations, and fire bans remain in effect. The UK is also forecast to experience a 'mini heatwave' this weekend, with London temperatures reaching 24°C, above seasonal norms. Authorities across all affected areas are urging residents to take precautions, including staying hydrated, avoiding strenuous activity, and not leaving people or pets in vehicles. The extreme heat in California is expected to peak on Friday and cool by early next week, while in Alberta and the UK, the heat is likely to persist through the weekend before easing.
