In late spring, southeastern Colorado looked wet enough. Then it didn't. A report this week from The Colorado Sun explains how a flash drought — defined by meteorologists as a drought that develops over weeks rather than months — stripped soil moisture from the plains fast enough to prime the landscape for the Sharpe fire before most households had even thought about fire season.
That speed is the thing worth sitting with.
What's actually changing
Traditional drought builds slowly. Farmers watch it. Water managers plan for it. Flash drought skips that ramp-up. Atmospheric heat pulls moisture out of soil faster than precipitation can replace it, and grasses that looked fine in April are cured and ignitable by mid-May. On the eastern plains and in the foothills, that's a meaningful shift — it means the period when you can safely say "fire season hasn't started yet" is shorter, and less reliable, than it was a generation ago.
The Sharpe fire is a plains fire, but the mechanism applies across Colorado's fire-prone zones. The Front Range foothills, the San Luis Valley margins, the Pawnee grasslands — all of them can flash-dry. The Colorado Division of Fire Prevention and Control has been tracking fire year start dates, and the trend is toward earlier and less predictable ignition windows. The National Integrated Fire Center's drought-fire correlation data shows the connection between rapid soil moisture loss and large fire growth is well-established; the flash drought dynamic simply accelerates that connection.
For households, the practical implication is this: you cannot use the calendar to decide when to get ready. "I'll do the defensible space work in June" is now a plan that may already be too late in some years.
What we'd actually do
Get your defensible space to Zone 1 compliance before Memorial Day weekend, not after. Colorado's Zone 1 — the 0-to-30-foot perimeter around your structure — is where ember catch happens. Dry leaves in gutters, dead grass against the foundation, wood piles against the house wall: these are ignition bridges. The Colorado State Forest Service offers free defensible space assessments; schedule one now, before fire restrictions limit your ability to do the clearing work. Don't wait for a red flag warning to start thinking about this.
Build a go-bag that assumes a 20-minute notice, not 2 hours. Flash drought conditions mean fires can move faster than standard evacuation timelines assume. The Ready, Set, Go model used by many Colorado county sheriffs is built around a warning period. In grass fires with 40 mph Chinook winds, that window compresses hard. A bag that lives by the door — documents, medications, phone chargers, two days of water, pet supplies — removes the decision-making from a moment when you won't be thinking clearly. Keep a second set of critical documents in a fireproof box or off-site.
Sign up for your county's emergency alert system this week, not someday. Colorado counties use different systems — some use Everbridge, some use Nixle, some have county-specific portals. El Paso, Pueblo, Huerfano, Las Animas, and Baca counties all cover terrain where the Sharpe fire dynamics are relevant. Go to your county OEM website, find the alert sign-up, and do it now. Relying on cell broadcast emergency alerts alone means you get the warning when the situation is already critical.
Check your home insurance policy's actual replacement cost coverage. This is the least dramatic item and possibly the most important one. After major Colorado fires, a consistent pattern has been that homeowners discovered their coverage hadn't kept up with construction cost inflation. Rebuilding costs per square foot have risen sharply over recent years. Call your insurer and ask specifically whether your dwelling coverage reflects current local rebuild costs. Ask about extended replacement cost riders if yours doesn't.
The Sharpe fire and the flash drought behind it are not a sign that Colorado is burning down. They are a signal that the seasonal assumptions most households use to time their preparedness are running behind the actual conditions on the ground. The goal here isn't to be afraid of May. It's to stop treating fire season as something that announces itself on a schedule.
Flash drought doesn't send a warning. Your preparation has to come before it arrives.
