If you're not loving this latest heat wave, here's some good news: today (aka Wednesday Sept. 28) is expected to be the last day of extremely high temperatures in and around Los Angeles County. Then, the weather should starting to cool on Thursday.

According to the National Weather Service, temperatures will start to drop in coastal areas first.

However, heat warnings issued by NWS are still in effect through the end of Wednesday for L.A.'s coastal valleys, inland Orange County, the valleys of San Bernardino and Riverside Counties and the Coachella Valley.

Those warnings are expected to be lifted by 8 p.m.

There's a slight chance for showers and thunderstorms across the mountains, high desert and eastern portions of the inland valleys.

Cool temperatures are expected to continue through the weekend.

And we can all be grateful here in Southern California that we're not in the path of Hurricane Ian, which has hit Florida with damaging winds and rains.

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)
