What to know about fire risks in North Texas

The National Weather Service has issued a red flag warning Monday, March 17 for parts of North Texas due to dangerously dry conditions.
NWS meteorologist Miles Langfeld said areas west of I-35 are under threat the afternoon of March 17, and the same warning extends further west of highway 281 for Tuesday, March 18.
“These areas have really dry conditions with humidity at less than 30%, and gusty southwest winds as high as 25-30 miles an hour at times. It could lead to rapid wildfire growth and spread if fires were to continue in this environment,” he said.
The Dallas-Forth Worth area is not currently under a red flag warning. But looking ahead, Langfeld warns that rain isn’t in the forecast until later this weekend—and even then, it’s only a slight chance.
The persistent dry vegetation, low humidity, and breezy conditions mean that fire weather risks could remain elevated to near-critical throughout the week.
Here’s what to know about the warnings and the risks they signal.
What is a red flag warning? What is a fire warning?
The National Weather Service issues a red flag warning when the forecast shows a dangerous mix of high temperatures, extremely low humidity, and strong winds — all of which can make it very easy for a fire to start and spread quickly.
In other words, these warnings are meant to alert fire managers and the public that conditions are “there for wildfires to experience rapid growth and spread if that fire was to occur,” Langfeld said.
That’s different from a fire warning, which is declared once a wildfire is already in progress and poses an immediate threat to lives and property.
“We issue that warning when we need people to evacuate,” Langfeld said.
Is North Texas in imminent danger?
While no active fire has been reported in the metroplex, the surrounding regions are at risk — and any careless spark could quickly escalate into a major incident.
“Today is just one of those days where, if you’re thinking of partaking in any activities that could lead to sparks and new fires, I would probably not do that,” Langfeld said. “We’re telling people across North Texas to just avoid activities that could lead to sparks because the conditions are there for fires to get out of control if they do start.”
What should I avoid?
During a red flag warning, fire danger is high, and even a small spark can lead to a fast-moving wildfire.
Here’s what the NWS says Texans should keep in mind to stay safe and prevent fires:
- Hold off on outdoor burning. This isn’t the time for campfires, debris burning, or anything involving open flames. Fires can spread quickly in dry, windy conditions.
- Dispose of flammable materials properly. Don’t toss cigarette butts or matches on the ground or out of a car window—dry grass can ignite in seconds.
- Secure burn barrels. If burning is allowed in your area, make sure your burn barrel has a tight, weighted metal lid with small ventilation holes to prevent embers from escaping.
- Be mindful with equipment. Lawn mowers, chainsaws, and even dragging trailer chains can throw off sparks. Avoid using these during dry, windy conditions if possible.
- Stay updated. Keep an eye on local fire weather alerts, follow any burn bans, and listen to officials if conditions change.
