The extreme heat is affecting over 35 million residents across California, with inland areas experiencing temperatures in the mid-90s°F (mid-30s°C). San Diego recorded 105°F (40.5°C) on Saturday, marking its first 100°F October day since 1987. The heat is exacerbating wildfire risks, as seen with the Bouquet fire in the Angeles National Forest, which prompted evacuation orders. Additionally, the prolonged heat could strain energy resources and increase health risks, particularly for vulnerable populations.
