850 PM MDT Fri Jun 20 2025
...RED FLAG WARNING FOR THE NORTHWEST PLATEAU, WEST CENTRAL
MOUNTAINS, WEST CENTRAL BASIN AND RANGE AS WELL AS THE UPPER RIO
GRANDE AND LOWER CHAMA RIVER VALLEYS 11 AM TO 9 PM SATURDAY DUE TO
STRONG WINDS, VERY LOW HUMIDITY, AND HIGH FIRE DANGER...
.South to southwest winds will trend stronger Saturday
afternoon, increasing the risk of rapid fire spread. Poor
overnight humidity recoveries, especially across western New

with daytime heating. Several hours of humidity values between
five and ten percent will further contribute to the rapid drying
of fuels across western New Mexico. Humidity values will not be as
low across the Upper Rio Grande and Lower Chama River Valleys,
however, several hours of sub-15 percent humidity is forecast.
