Los Angeles County officials are sounding the alarm about the holiday heat wave that will envelop Southern California on and around Independence Day.

The Department of Public Health on Monday issued an excessive heat warning for the following areas between Tuesday and next Monday, July 8.

  • Eastern Antelope Valley
  • Western Antelope Valley
  • Antelope Valley
  • Western San Gabriel Mountains/Hwy 14 Corridor
  • Northwest L.A. County Mountains

Southern Californians should take precautions to avoid becoming overheated, officials said.

Here are some tips to keep cool:

  • Drink plenty of water and stay hydrated
  • If you go outside, try to go out during the cooler hours of the morning or evening
  • Wear lightweight, light-colored clothing
  • Wear sunscreen
  • Call 911 if someone experiences high body temperature, vomiting, dizziness, confusion and red, hot, dry or damp skin

“Although it’s crucial that we take care of ourselves, it’s equally important that we extend our hand to those in need,” said Dr. Muntu Davis, Los Angeles County health officer. “We must look out for those who are more likely to get ill due to the heat, including the elderly, unwell, pregnant women, children, and those living alone. Hot days aren’t just uncomfortable — they can be dangerous. However, if we make sure to stay hydrated and keep cool, we can protect ourselves and our loved ones, friends, and neighbors. If you have an elderly or unwell family member or neighbor, check on them regularly to ensure they are safe and well.”
