With strong, gusty northwesterly 20-foot winds and relative humidity dropping to between 10 to 25% Thursday into Friday, the National Weather Service in Brownsville/Rio Grande Valley has issued a Fire Weather Watch.
The Fire Weather Watch will be in effect from 3 p.m. Thursday until noon Friday for the entire Valley.
According to NWS, any fires that develop will likely spread rapidly and outdoor burning is not recommended.
“Erratic wildfire behavior is possible Thursday Night and Friday. This could lead to briefly uncontrolled growth of any wildfire in dry grass/brush to spread to tens of acres in just a few hours,” the NWS reports.
Cigarette smokers are urged to dispose of cigarettes in ashtrays rather than tossing them on the ground or out of the windows of their vehicles.
