Coastal areas, meanwhile, will stay cool in the 70s and dense fog will cover the coast this morning.

Some daytime highs to note:

  • 101 degrees in Woodland Hills
  • 86 degrees in Anaheim
  • 88 degrees in downtown L.A.
  • 95 degrees in Ontario

Several heat advisories and excessive heat warnings kick in tomorrow for the valleys, mountains, inland areas and deserts. Forecasters say temperatures will be in the upper 90s to low 100s. The Inland Empire could reach up to 108 degrees in the next few days.

The warnings end Wednesday, which means we could see some cooling Thursday.

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 a pet from excessive heat

  • 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 a human from excessive heat

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," says the CDC)
