About those heat warnings

Weather forecasters have issued a red flag warning for today — they say the dry conditions and scorching temperatures mixed with fireworks popping off will increase the risk of wildfires.

The red flag warning applies to the 5 Freeway corridor, Antelope Valley foothills and Ventura County mountains through Saturday evening.

And if you're heading to the beaches in L.A. or Orange counties, look out for strong swells and high surf, with sets up to 7 feet tall expected, mainly for the south facing beaches.

L.A. County valleys, Inland Empire and deserts remain under excessive heat warning for the rest of the week. Areas that include downtown L.A., Irvine, and the Santa Ana foothills are under a heat advisory until Sunday night as temperatures will likely reach up to 105 degrees.

Staying safe in the heat

  • Don't wait until you're thirsty to drink water or electrolyte replacements.
  • Drink cool water, not extremely cold water (which can cause cramps).
  • Avoid sweetened drinks, caffeine and alcohol.

Protect pets

  • Never leave a pet or animal in a garage.
  • Never leave a pet or animal in a vehicle.
  • Never leave a pet or animal in the sun.
  • Provide shade.
  • Provide clean drinking water.

Protect people

Check in frequently with family, friends and neighbors. Offer assistance or rides to those who are sick or have limited access to transportation. And give extra attention to people most at risk, including:

  • Elderly people (65 years and older).
  • Infants.
  • Young children.
  • People with chronic medical conditions.
  • People with mental illness.
  • People taking certain medications (i.e.: "If your doctor generally limits the amount of fluid you drink or has you on water pills, ask how much you should drink while the weather is hot," the CDC recommends).
