Red Flag Warning issued March 11 at 1:00PM CDT until March 12 at 9:00PM CDT by NWS Austin/San Antonio TX

Effective: Tue March 11, 2025, 1:00 PM
Expires: Wed March 12, 2025, 4:00 AM

...STRONG WINDS AND A DRY AIRMASS BEHIND A DRYLINE AND PACIFIC FRONT WILL RESULT IN CRITICAL WEATHER CONDITIONS... .A dryline advancing eastward Wednesday morning quickly becomes overtaken by a Pacific front in the afternoon. Critical fire weather conditions develop in the wake of these boundaries. These conditions are expected to first develop across the southern Edwards Plateau midday Wednesday, then develop southeast down the Rio Grande and east into the Hill Country mid afternoon, and then potentially into the I-35 corridor late afternoon and early evening. The National Weather Service in Austin/San Antonio has issued a Red Flag Warning for low humidity and gusty winds, which is in effect from 4 PM to 9 PM CDT Wednesday. * AFFECTED AREA...I-35 corridor. * TIMING...From 4 PM to 9 PM CDT Wednesday. * WINDS...West 10 to 20 mph with gusts up to 30 mph. * RELATIVE HUMIDITY...As low as 15 to 20 percent. * TEMPERATURES...Upper 80s to lower 90s. * IMPACTS...Any fires that develop will rapidly increase in size and intensity, move quickly, and be very difficult to control.

A Red Flag Warning means that critical fire weather conditions are either occurring now....or will shortly. A combination of strong winds...low relative humidity...and warm temperatures can contribute to extreme fire behavior.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
