The National Weather Service has posted 48 active Red Flag Warnings and fire weather alerts stretching across eight states — Arizona, California, Colorado, Massachusetts, Maine, New Jersey, New Mexico and New York — as forecasters warn that any spark could quickly grow out of control.
Colorado carries the bulk of the warnings today. The Colorado River Headwaters zone and the Lower Colorado River zone below 8,000 feet are both under warnings from noon through 8 p.m. MDT, with southwest winds of 10 to 20 mph gusting as high as 35 mph and relative humidity dropping to 8 to 13 percent in the headwaters area and as low as 5 to 10 percent along the Lower Colorado River. The National Weather Service says outdoor burning is not recommended in the affected zones, and any fire that starts is expected to catch and spread quickly. A Fire Weather Watch is also in place for Thursday afternoon into Thursday evening across parts of the state, signaling the dry, windy pattern will persist beyond today.
The warnings extend well beyond the Rockies. Additional Colorado fire weather zones — including the Southwest Colorado Lower Forecast Area, Paradox Valley, Northern San Juan, North Fork, Gunnison Basin and the Southwest Colorado Upper West and Upper East forecast areas, along with southeast Utah — are also flagged. In the Northeast, county-level warnings cover Passaic, Hudson, Bergen, Essex and Union in New Jersey, along with sections of Park, Jefferson, Douglas, Gilpin, Clear Creek and Elbert counties in Colorado above 6,000 to 9,000 feet.
The National Weather Service defines a Red Flag Warning as a signal that critical fire weather conditions are either underway or expected shortly, driven by the combination of strong winds, low relative humidity and warm temperatures. Under those conditions, any ignition — from a downed power line to an unattended campfire — can spread rapidly and become difficult to control. Residents in warned areas are advised to avoid outdoor burning, secure equipment that can throw sparks, and have evacuation plans ready.
With 48 separate alerts active across eight states from the Southwest to the Northeast, the pattern underscores how widespread dry, breezy conditions have become heading into midsummer. Forecasters will be watching whether the warm, low-humidity pattern extends further into the week, particularly as Colorado’s Thursday watch could convert to additional warnings if winds and dryness persist as expected.
