A red flag warning does not necessarily mean there is a fire ongoing – extreme fire weather conditions are either occurring now, or will shortly, according to the NWS. If a fire does start, it has the potential to quickly become extreme due to the critical fire weather conditions.

“Exceptionally dangerous” fire weather conditions will develop over North Texas on Friday, March 14, according to the National Weather Service Fort Worth.

According to the National Weather Service, a lack of rain over the last couple of years has led to extreme drought. Dry vegetation creates a tinder box for wildfires. Embers jump quickly with strong winds, and with extreme drought it doesn't take much for a wildfire to spread.
