By Monday afternoon, temperatures will be 15 to 20 degrees above normal across a vast portion of the eastern US, and by Tuesday through Friday, they could surge to as much as 25 degrees above normal. This will likely result in hundreds of temperature records being shattered, both during the day and at night.
Wildfire Risks
The intensifying heat dome not only brings extreme temperatures but also heightens the risk of wildfires. According to the National Interagency Fire Center, fire activity is increasing nationwide, with nearly a dozen large fires currently burning in the western US. Hot, dry conditions have persisted in the West since early June, drying out wildfire fuels such as grass and plant life, making them more susceptible to ignition and spread.
Winds are expected to pick up later this weekend and into early next week, further exacerbating the wildfire risk. Gusty winds can cause wildfires to spread rapidly, as demonstrated by the Corral Fire in California earlier this month. The Rose Fire in Arizona, about 70 miles northwest of Phoenix, has already destroyed 15 structures, including seven homes, and at least a dozen vehicles. As of Thursday evening, the fire had burned through 166 acres and was only 20% contained.
Preparing for the Heat Wave
Residents in the affected regions are urged to take necessary precautions to stay safe during the extreme heat. This includes staying hydrated, avoiding strenuous outdoor activities during peak heat hours, and checking on vulnerable populations such as the elderly and those with pre-existing health conditions. Additionally, staying informed about local weather forecasts and adhering to any advisories or warnings issued by authorities is crucial.
