The UK experienced its hottest day of the year today, with temperatures reaching 30C, according to the Met Office.

A four-day heat health alert has been issued starting today for most of England, as temperatures are expected to reach 31C in some areas. Forecasters have also predicted that today will be the warmest day of the week.

A "heat dome" has settled over the West Coast, bringing scorching temperatures of up to 112F and creating dangerous conditions for over 10 million people in California, Nevada, and Arizona. This phenomenon is expected to persist throughout the week, posing a serious threat to residents in the region. The extreme heat has raised concerns about the potential for wildfires, as dry conditions and high temperatures increase the risk of ignition. Authorities are urging residents to take precautions to stay safe and avoid activities that could spark fires. The heat dome is expected to bring "dangerous heat" to the affected regions, making it essential for people to stay hydrated, seek shelter in air-conditioned spaces, and avoid prolonged exposure to the sun. It is crucial for individuals to take care of themselves and their loved ones during this challenging time. As the heat wave continues to impact the West Coast, it is important for everyone to stay informed about the latest updates and follow guidelines from local authorities to ensure their safety.
