North and Central Texas areas again face critical fire weather conditions on Monday.
Western areas of North and Central Texas are under a red flag warning from 11 a.m. to 10 p.m., according to the National Weather Service in Fort Worth.
“Very low humidity and gusty winds of 30 to 35 mph will make any fires that start difficult to control,” the weather service said on its website.
Areas east of Interstate 35 face an elevated risk of fire weather conditions as well, with relative humidity between 15% and 30%, and wind gusts 25 to 30 mph.
Understanding Red Flag Warnings
A red flag warning is issued when conditions create an elevated risk for wildfires.
According to the weather service, this happens when “10 hour fuels” are at 8% or less. This describes how much water is held by small vegetation, meaning the vegetation, such as small sticks or grass, takes 10 hours to respond to a change in dry or wet conditions.
A low amount of water held means vegetation can become fuel for a quick-spreading wildfire. In addition to the fuels, red flag warnings are issued when relative humidity in an area is less than 25% for several hours and winds are at least at 15 mph for several hours.
Critical fire weather concerns will exist across western North and Central Texas this afternoon and evening. As such, a Red Flag Warning is in effect from 11 AM through 10 PM.
Red Flag Warning vs Fire Warning
A red flag warning is different than a fire warning. A red flag warning means conditions exist that could lead to a wildfire. A fire warning is issued when there is an active fire spreading that is threatening life and property.
A Red Flag Warning does not necessarily mean there is a fire ongoing, but that conditions will be extremely dry and windy. If a fire does start, it has the potential to quickly become extreme due to the critical fire weather conditions.
Precautions to Take During Red Flag Warnings
The weather service warns residents to be cautious of activities that could spark a wildfire. Avoid outdoor fires, and do not park or drive vehicles over tall grass, as a running engine heats up the undercarriage of a vehicle, which could spark dry vegetation underneath it.
Be sure to carefully dispose of cigarettes, and never toss one while it is still lit.
Conclusion
In conclusion, red flag warnings are an important indicator of critical fire weather conditions. By understanding what a red flag warning means and taking necessary precautions, residents can help prevent wildfires and stay safe during periods of high fire risk.
