Santa Anna, Texas
Community in Starr County, Texas...STRONG NORTHERLY WINDS FRIDAY NIGHT INCREASE WILDFIRE THREAT... .A strong front pushes south through Deep South Texas and the Rio Grande Valley on Friday, with a secondary surge of strong northerly winds arriving late Friday evening into late Saturday morning. Relative humidity values are expected to drop Friday afternoon with little to no recovery into Saturday morning. Any wildfire that can develop will behave dangerously with erratic growth and spread due to strong winds and lower humidity. A Red Flag Warning is in effect. The National Weather Service in Brownsville has issued a Red Flag Warning for Red Flag Warning, which is in effect from 1 PM Friday to 7 AM CDT Saturday. The Fire Weather Watch is no longer in effect. * WINDS...Northerly 15-25 mph, gusting as high as 35-55 mph. * RELATIVE HUMIDITY...As low as 25 to 40 percent. * IMPACTS...Any fire that can develop will behave dangerously with erratic growth and spread.
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.
