Canyon Lake is under a Red Flag Warning again from 10 a.m. to 8 p.m. today due to wind and low relative humidity for portions of south-central Texas west of a Taylor-Seguin-Kenedy line.
A Red Flag Warning means critical fire weather conditions are either occurring now or will shortly, the U.S. National Weather Service Austin/San Antonio said in an advisory today. Any wildfires ignited could spread rapidly and unpredictably.
The public is asked to avoid activities that cause sparks or flames, to properly dispose of cigarettes, check trailer chains, avoid parking on grass, and obey city/county /state burn bans.
Comal County is under a burn ban, with exemptions for days when wind speeds are under 15 mph and humidity is over 25%.
The area also is under a wind advisory for gusts up to 40 mph from 1 p.m. today to 4 a.m. Wednesday. Showers and storms will move into Canyon Lake sometime after midnight. There is a low chance for a strong to severe storm producing gusty winds.
Winds currently are from the south, blowing between 15 to 25 mph with gusts of up to 40 mph. Relative humidity could be as low as 32%.
Behind the Pacific cold front Wednesday, gusty west winds will usher in a very dry air mass, the Weather Service said. More Red Flag Warnings and wind advisories also are expected, primarily over the west half of south-central Texas.
Extremely critical fire weather conditions are expected in the High Plains and Rolling Plains regions, Lone Star State Incident Management Team-Texas A&M Forest Service said. A Southern Plains wildfire outbreak also could develop under these conditions.
“Any wildfire that ignites in dry grass could move at a rate of four- to six- mph with flame lengths of 10 to 12 feet, which equates to flames the height of a one-story building burning the length of a football field in a minute,” the Forest Service said in an advisory.
