The Los Angeles County Department of Public Health is warning of dangerous temperatures in multiple areas of Southern California for the first part of this week.

Temperatures could hit 110 degrees in some areas, as reported by the Los Angeles Times.

The following areas are under an excessive heat warning through Tuesday:

  • Antelope Valley
  • Western Antelope Valley
  • Eastern Antelope Valley
  • Santa Clarita Valley
  • Western San Gabriel Mountains/Highway 14 Corridor
  • West San Fernando Valley
  • Calabasas/Agoura Hills

In addition, the following locations are under a heat advisory through Tuesday:

  • Northwest L.A. County Mountains

  • San Gabriel Valley
  • Los Angeles Inland Coast

Officials are urging residents to take precautions against the heat, including wearing light-colored and lightweight clothing, remaining hydrated and avoiding the heat of the day.

But in addition to preparing ourselves, we also need to look out for the health of others, as Dr. Muntu Davis, L.A. County health officer, explained in the Public Health release.

“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,” said Davis. “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.”
