On Thursday at 5:08 p.m. the National Weather Service issued an updated red flag warning valid from Friday 10 a.m. until Saturday midnight for Northeast Weld County.
Residents can expect winds to be southwest 15 to 25 mph with gusts up to 40 mph and relative humidity as low as 15 percent.
“Strong west winds, sustained 45-55 mph with gusts upwards of 85-105 mph, are expected in the foothills of Boulder and Jefferson counties beginning early Friday morning. Relative humidity values are expected to drop into the low teens, possibly upper single digits. While Red Flag conditions, critical fire weather, are expected across a larger area in northern Colorado, the most extreme conditions are expected to be along Highway 93 from Jefferson County into Boulder County and along US-36 north of Boulder to the Larimer County line and westward. There will be a high potential for fast moving wildfires, should any new starts occur. Winds toward I-25 and eastward will be slower to develop, and also speeds will be considerably lighter. That said, gusts of 25-40 mph are still expected to combine with very low humidity and cured grasses to support critical fire weather conditions. Areas farther east into eastern Adams, Arapahoe, Elbert, and Lincoln counties have more uncertainty if those winds even develop, so those locations remain under a Fire Weather Watch. Such conditions may be a longer duration than usual, with potential for low humidity to extend well into the evening hours,” explains the NWS. “Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.”
What is the significance of a red flag warning?
A red flag warning indicates that either extreme fire weather conditions are currently happening or will happen soon, as per 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. Secure burn barrels:
If burning is permitted in your area, ensure that all burn barrels have a weighted metal cover, complete with holes no larger than 3/4 of an inch.
2. Responsible 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. 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 mitigating the risk of wildfires during these perilous conditions. Prioritize safety, stay well-informed, and act responsibly to safeguard lives and property.
