5 Freeway north of LA was placed under a red flag warning by the National Weather Service on Wednesday at 2:46 p.m. The warning is in effect until Thursday July 16, at 9 a.m.
Residents can expect winds to be northwest to north winds 20 to 30 mph with gusts of 30 to 50 mph, strongest in Sundowner wind prone areas of southern Santa Barbara County and relative humidity 10 to 25%.
“Gusty northwest to north winds, hot temperatures, and low relative humidity will produce the potential for critical fire-weather conditions through early Thursday,” according to the NWS Los Angeles/Oxnard CA. “If fire ignition occurs, conditions are favorable for extreme fire behavior, rapid fire growth, and long range spotting, which could threaten life and property. The hot air mass will also contribute to the potential for significant vertical plume growth.”

What is the significance of a red flag warning?
A red flag warning means that extreme fire weather conditions are either occurring now or will shortly, according to the NWS. Warm temperatures, very low humidities, and stronger winds are expected to combine to produce an increased risk of fire spreading rapidly.
What should you do under a red flag warning?
A red flag warning demands vigilance and immediate readiness to respond to potential fires. The NWS provides these vital guidelines to minimize fire hazards and ensure your safety:
1. Bolster burn barrel safety:
If burning is authorized in your vicinity, ensure that all burn barrels feature a weighted metal cover with holes no larger than 3/4 of an inch.
2. Mindful handling of smoking materials:
Never discard lit cigarette butts outside, and avoid tossing cigarettes or matches from a moving vehicle. These seemingly small actions can lead to dry grass ignition, potentially sparking a wildfire.
3. Properly extinguish outdoor fires:
To prevent inadvertent fires, diligently douse all outdoor fires. Quench them with a copious deluge of water and stir to guarantee complete cooling. Submerge charcoal until it’s thoroughly bereft of residual heat. Never depart from live charcoal unattended.
4. Never leave fires unattended:
Avoid leaving any fire unattended. Even sparks or embers carried by the wind can ignite nearby leaves or grass, triggering a fire that spreads rapidly.
Understanding the gravity of a red flag warning and adhering to these precautions is pivotal in reducing the risk of wildfires during these hazardous conditions. Prioritize safety, stay informed, and act responsibly to protect lives and property.
