Red Flag Warning is in effect for the counties in pink from 11 a.m. to 5 p.m. Wednesday (Copyright 2023 by KSAT - All rights reserved.)

The National Weather Service issued a Red Flag Warning, which will go into effect Wednesday from 11 a.m. to 5 p.m. for Bandera, Blanco, Dimmit, Edwards, Frio, Gillespie, Kendall, Kinney, Maverick, Medina, Real, Uvalde, Val Verde, and Zavala counties.

A Red Flag Warning means that the weather conditions will lead to high grassfire danger. It will be dry Wednesday, with relative humidity values of 8-15%. Winds will be from the west-southwest at 15-25 mph, gusting up to 35 mph.

It’s been incredibly dry, so any fires that develop would spread rapidly. To avoid creating a fire:

  • No campfires or burn piles
  • Avoid using tools that create sparks like chainsaws
  • Dispose of cigarettes properly
  • Don’t drag trailer chains
  • Don’t park vehicles on grass
