Record Heat Wave Worsens Red Flag Fire Weather Warning
High Temperatures Bring Increased Risk of Wildfires
A week of record high temperatures includes a red flag fire weather warning for part of Los Angeles County during what is historically one of the most dangerous times of the year for wildfires. Temperatures are expected to cool slightly this weekend, but not before above-normal heat that warranted excessive heat warnings and advisories through at least 8 p.m. Thursday. Some areas are expected to reach well into triple digits Thursday in the Santa Clarita and San Fernando valleys.
Red Flag Warning in Effect
A red flag warning will be in effect until 8 p.m. Thursday for the western San Gabriel Mountains and the 5 and 14 Freeway corridors, extending into the LA and Ventura county mountains. The warning, indicating critical fire danger, was issued due to heat, gusty northeast winds, and low humidity.
High Risk for Fire Growth and Spread
"There is a high risk for fires growing and, unfortunately, spreading," said NBC4 forecaster Belen De Leon. "A lot of this has to do with these temperatures. We are way above normal." The warning comes as three major wildfires that started nearly a month ago continue to burn in several Southern California counties.
Fire Updates and Statistics
The most active fire, the Line Fire in San Bernardino County, was 79% contained at 43,900 acres, with some evacuations still in effect. According to Cal Fire stats updated on Tuesday, 6,528 wildfires have burned 1,001,993 acres this year, bring California close to its five-year average for early October of 1,085,577 acres.
Cooler Weather Expected but Danger Still Present
Temperatures will cool slightly this weekend, but only after the excessive heat this week. Some areas are likely to fall under excessive heat watches or warnings again this weekend with only slight cooling. Much cooler weather is expected by Tuesday, but fall is typically the worst time of the year for wildfires in Southern California due to dry conditions and the infamous Santa Ana Winds, which have fanned some of the region’s most destructive fires.
Community Remains Under Evacuation Warning
The community of Big Bear Lake, including Moonridge, Sugarloaf, and south Erwin Lake, was under an evacuation warning on Tuesday. Christian Cázares reports on Tuesday’s evacuation warning at the NBC4 News.
Southern California Temperature Records
Some communities shattered high temperature records on Wednesday. Temperatures will continue to soar above normal, bringing concerns about fire danger. Some temperature records broken included:
• Woodland Hills reaching 111, breaking the record for the day of 109 set in 1991.
• Palmdale Airport reaching 105, breaking the record for the day of 101 set in 2020.
• It was 104 at Lancaster Fox Field, breaking the record for the day of 101 set in 2012.
Conclusion
This week’s excessive heat wave has brought serious concerns about fire danger and risk. With temperatures remaining above normal, it’s essential for residents to exercise extreme caution and follow warning advisories. Cooler weather is expected in the near future, but the dangers posed by wildfires are likely to continue.
