The National Weather Service has 36 active Red Flag Warnings Tuesday across 11 states — up from 21 Monday — as fire weather conditions pushed into Florida and Texas, two states absent from Monday’s alert zone.
The expansion marks the widest geographic footprint of this outbreak, which totaled just six warnings across four states as recently as Sunday. Florida and Texas have now joined Colorado, Idaho, Nebraska, New Mexico, Oregon, South Dakota, Utah, Washington, and Wyoming under active fire weather alerts.
The most prolonged threat is forecast in New Mexico, where a Red Flag Warning covers the Northwest Plateau from 1 p.m. to 7 p.m. MDT Tuesday, immediately followed by a Fire Weather Watch posted for Wednesday afternoon through Wednesday evening. That watch extends to the West Central and North Central Mountains, the Middle Rio Grande Valley, and the Sandia and Manzano Mountains — a back-to-back cycle signaling that overnight recovery will be marginal and conditions are expected to redevelop Wednesday.
In northeastern Wyoming and southwestern South Dakota, warnings remain in effect through 8 p.m. MDT Tuesday for Fall River County, Pine Ridge, Southern Campbell, and Weston County Plains. The National Weather Service described conditions there as “very warm, dry, and windy,” with widespread critical fire weather expected across the region this afternoon. Casper weather and the Natrona County BLM zone are also under active warning.
Colorado’s Upper Arkansas River Valley — including Lake County and Chaffee County — is under warning. Idaho’s alerts span multiple federal land districts, from the Upper Snake River Valley near Idaho Falls south through the Caribou Range and Caribou National Forest to BLM tracts around Twin Falls.
Florida’s entry into the list comes via air quality, not proximate wildfire. Broward County’s Natural Resources Division issued an alert for fine particulates, warning that concentrations may approach or exceed unhealthy standards across inland, metro, and coastal sections of the county. Residents can check current Air Quality Index readings at airnow.gov. The Fort Lauderdale weather page has the local forecast.
A Red Flag Warning indicates that a combination of strong winds, low relative humidity, and warm temperatures is either occurring or imminent — conditions under which fires ignite quickly and spread with limited warning. The National Weather Service urges field crews in all active zones to treat warnings as in force until officially lifted.
