Pueblo, Colorado – A volatile mix of 65 mph wind gusts and humidity as low as 5 percent will sharply increase wildfire ignition and spread risk across southern Colorado by Wednesday afternoon, creating conditions where a single spark could trigger rapid fire growth.
According to the National Weather Service in Pueblo, a Particularly Dangerous Situation Red Flag Warning is in effect from 11 a.m. through Wednesday evening, targeting the San Luis Valley, Wet Mountain Valley, and large portions of the Central Mountain Region. Forecasters warn southwest winds will sustain at 20 to 40 mph, with peak gusts reaching 65 mph, especially along exposed ridgelines and valley corridors.
Communities from Alamosa and Trinidad to Pueblo and Walsenburg face the highest threat window between midday and early evening. Fire officials say grasses and brush are critically dry, allowing flames to spread faster than containment crews can respond. In Fremont and Huerfano counties, any roadside spark or equipment use could escalate into a fast-moving wildfire within minutes.
Travelers along Highways 50 and 160 may encounter sudden crosswinds capable of pushing vehicles, especially high-profile trucks, off course. Power infrastructure is also at risk, with strong gusts capable of downing lines and triggering outages.
Residents are urged to avoid outdoor burning, delay yard work involving machinery, and secure trailer chains to prevent roadway sparks. Emergency managers stress that even routine activities can ignite fires under these conditions.
The warning remains in effect through Wednesday evening, and additional fire weather alerts could follow if dry, windy conditions persist into late week.
