On Tuesday at 10:28 a.m. the NWS San Diego CA issued a red flag warning valid from 5 p.m. until Wednesday 11 a.m. for Victor Valley - Apple Valley - Lucerne Valley - Johnson Valley.

"The National Weather Service in San Diego has issued a Red Flag Warning for dry lightning and gusty outflow winds, which is in effect from 5 p.m. this afternoon to 11 a.m. Wednesday," according to the NWS.

This warning is in effect until Wednesday at 11 a.m.

What does a red flag warning indicate?

A red flag warning implies that either extreme fire weather conditions are currently taking place or will occur shortly, according to the NWS. Warm temperatures, very low humidities, and stronger winds are expected to combine to produce an increased risk of fire to spread rapidly.

What are the recommended measures to take during 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:

In areas where controlled burning is sanctioned, make certain that burn barrels sport a weighty metal cover, equipped with holes no larger than 3/4 of an inch.

2. Mindful disposal 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. Prudent fire extinguishing practices:

To safeguard against accidental fires, diligently extinguish all outdoor fires. Drown them with an ample amount of water and stir to confirm that everything is cold to the touch. Submerge charcoal in water until it's thoroughly cooled. Never dispose of live charcoal on the ground.

4. Never leave fires unattended:

Avoid abandoning any fire without supervision. Even minor sparks or drifting embers can incite nearby foliage or grass, setting off a rapidly spreading fire.

Understanding the gravity of a red flag warning and adhering to these precautions is paramount in averting wildfires during these perilous conditions. Prioritize safety, stay impeccably informed, and assume responsibility to shield lives and property.
