The San Antonio Fire burning on Valles Caldera National Preserve grew from about 100 acres Thursday evening to 426 acres this morning.
Kimberly DeVall, a spokeswoman for the preserve, said additional crews had been ordered to battle the lightning-caused blaze burning in the northwest corner of the preserve.
According to a news release, a Type 3 incident management team will take command of firefighting efforts at 8 a.m. Saturday. There are already more than 100 fire personnel on scene.
DeVall said Friday morning the fire is burning just north of where a prescribed burn had been conducted earlier this spring.
Fire officials say smoke from the fire may linger in neighboring communities, including Los Alamos, Jemez Springs, Jemez Pueblo and other communities near N.M. 4, which remains open to traffic. They say the smoke could cause health concerns for children, senior citizens, pregnant women and those who suffer from allergies, asthma, sensitivity to chemicals, or other heart and lung diseases.
“To reduce exposure to smoke, stay indoors as much as possible with windows, doors, and vents closed. Avoid or limit physical activities,” they warn.
Despite the fire, the Valles Grande entrance station and bookstore remains open and ranger-led tours and hikes are still being offered in the park’s cabin district, according to the news release.
