LA fires live updates: At least 25 fire-related deaths, medical examiner says

The next 24 hours will be very dangerous as high winds blow through the Los Angeles area, LA County Sheriff Robert Luna warned.

He urged residents to follow evacuation orders, noting that many people who waited until the last minute to evacuate last week suffered significant burns.

"We don’t want you to impact your own life or the life or your loved ones," Luna said.

The sheriff’s department is following 24 missing persons cases, all adults, Luna said. The LAPD said it has 13 active missing persons cases, two of whom are believed to be dead.

No more remains were found when crews searched the hard-hit Altadena area on Monday, the sheriff said.

Dangerously high winds that could fuel wildfires are impacting the Los Angeles area Tuesday and Wednesday.

The highest wind gust recorded so far was 72 mph in the western San Gabriel Mountains, which is in northern LA County.

A 50 mph wind gust was recorded in Malibu Hills.

The gusty winds will spread from the mountains into the valleys and the canyons by Tuesday afternoon.

A slight break in the wind is expected Tuesday evening before the rough winds pick back up Wednesday morning.

The winds will stay strong into Wednesday afternoon and then finally begin to relax Wednesday night into Thursday.

A "particularly dangerous situation" with a red flag warning will go into effect in western Los Angeles County and most of Ventura County on Tuesday, weather officials said, with winds threatening to further fuel historic Southern California wildfires.

The warning begins at 4 a.m. local time. Winds are forecast to gust between 45 mph to 70 mph, with relative humidity as low as 8%.

Winds overnight and early on Tuesday have been gusting up to 67 mph in the mountains near Los Angeles. The West San Gabriel Mountains have seen gusts up to 67 mph, with the Central Ventura County Valley hit about 66 mph.

The strongest gusts are expected Tuesday morning and early afternoon, which will then be followed by a break in the evening. More gusty winds are expected Wednesday morning.
