Congress has cut federal funding for public media — a $3.4 million loss for LAist. We count on readers like you to protect our nonprofit newsroom. Become a monthly member and sustain local journalism.

In store for today's weather forecast — more Santa Anas, a red flag warning, wind advisories and even a freeze advisory for some areas (spooky!)

Quick Facts
    • Today’s weather: Warm, windy
    • Beaches: mid 70s
    • Mountains/deserts: 60s-70s/65-79
    • Inland: low 80s
    • Warnings and advisories: Red Flag Warning, Wind Advisories, High Wind Warning, Freeze Warning

Over on the coasts — where some of the strongest Santa Ana winds will be felt — you can expect a high of 79, up to 84 in Long Beach and 80 degrees in Newport Beach.

In downtown Los Angeles, temperatures will reach up to 85. In the valleys, the highs will reach up to 84, and up to 80 in inland Orange County. In Riverside and San Bernardino counties, temperatures are a few degrees cooler with highs up to 83.

The deserts are much cooler as we head into winter — a high of 65 in the high desert and up to 79 in the low desert.

About those advisories

Here's a list of advisories to look out for and the details:

Red Flag Warning (until 10 p.m. tonight) for L.A. and Ventura Counties

  • Remember, "any fire starts will have really conducive weather to rapid and dangerous fire growth," said National Weather Service meteorologist Rose Schoenfeld. "It's important to take precautions with regards to anything flammable, different vehicles can spark things, and it means that there's a possibility of power outages as well."

Here's a good resource for how to stay prepared during a red flag warning.

High Wind Warning (until 10 p.m. tonight)

  • Applies to the Inland Empire, Santa Ana foothills, Orange County inland areas, San Fernando Valley, Santa Monica and San Gabriel Mountains, and Interstate 5 and Highway 14 corridors.
  • Local gusts can range between 60 to 65 mph.

Wind Advisories (from 10 p.m. tonight until 8 p.m. Tuesday)

  • Applies to Inland Empire, Santa Ana mountain and foothills, Orange County inland areas, Orange County coasts, Santa Monica Mountains, San Fernando Valley.
  • Expect winds between 20 to 35 mph, with gusts up to 55 mph.

Freeze Warning (from 8 a.m. today, and again from 2 a.m to 8 a.m. Tuesday)

  • Applies to the Antelope Valley. Frost could kill crops and other sensitive vegetation and extended exposure could lead to hypothermia for pets and people. Remember to check on your loved ones.
Tips
  • State law requires residential units to have heating systems that can keep indoor temperatures at a minimum of 70 degrees. That means every dwelling unit and guest room offered for rent or lease should offer heating equipment, usually central air conditioning (A/C) or a wall heater. — Caitlin Hernández

  • Use heat smartly to save money: Cranking things like the A/C and wall heaters can be expensive. If money is tight, be judicious about how and when you use your utilities. For example, only use heaters at night or only set the thermostat to around 70 degrees.

  • Open and close those vents: If you have central A/C, look at where the vents are around your home. Are any open in places where you don’t stay long? Practice opening and closing those so warm air only goes where you need it (most vents should have a small toggle lever). Humidifiers can also help you warm things up — and it’s useful to add moisture into our dry air.

  • Adjust your wall heaters: If you have a wall heater, you can change the output by adjusting the knob (usually at the bottom). Since wall heaters can only warm the areas where they’re placed, it’s essential to close doors to rooms you won’t be in so hot air doesn’t get wasted.

  • Turn on your ceiling fan (really): If you have a ceiling fan, try turning it on. This sounds counterintuitive, but there’s science behind it. The direction a fan turns can push air in different directions, and since hot air floats up, you’ll want to move that around. Your fan should spin clockwise to create an updraft to circulate. Not all fans will have this option, though.

This day in history

On this day in 1971, the most intense cold snap on record for October spread to the mountains and valleys where in Riverside, it reached 30 degrees.

Things to do

It's the night before Halloween! Anything can happen! How about continuing the spooky festivities with this:

  • 'Dial M For Murder' in 3-D: Academy Award winners Grace Kelly and Ray Milland star as a couple with a marriage on the rocks in this 1954 classic thriller. She's having an affair — and he wants to kill her. When his plot goes awry, she gets implicated in another murder. Directed by Alfred Hitchcock.

As Editor-in-Chief of our newsroom, I’m extremely proud of the work our top-notch journalists are doing here at LAist. We’re doing more hard-hitting watchdog journalism than ever before — powerful reporting on the economy, elections, climate and the homelessness crisis that is making a difference in your lives. At the same time, it’s never been more difficult to maintain a paywall-free, independent news source that informs, inspires, and engages everyone.

LAist has been there for you and we’re asking you to be here for us.

We rely on donations from readers like you to stay independent, which keeps our nonprofit newsroom strong and accountable to you.
