Boulder County is staring down a Fire Weather Watch on Thursday, and officials are not taking any chances. With gusty winds and very low humidity in the forecast, the sheriff’s office warns that even a tiny spark could turn into a fast-moving problem. The watch is in effect from 11 a.m. to 5 p.m., and open burning, including agricultural burns, is off-limits through midnight Thursday.
The alert went out in a Facebook reel from the Boulder County Sheriff's Office, which credited the National Weather Service for issuing the watch and reminded residents to skip any outdoor burning while it is active. According to the Boulder County Sheriff's Office, the ban applies across the entire county for the duration of the watch.
What the watch means
A Fire Weather Watch signals that conditions could produce dangerous fire behavior within the next day or two, typically when dry fuels line up with strong winds and low relative humidity. The National Weather Service Denver/Boulder office advises that outdoor burning and any spark-producing activities should be avoided during watches and warnings, because fires can grow and spread rapidly under those conditions.
Open burning prohibited and enforcement
Boulder County’s fire restriction rules automatically ban open burning whenever the National Weather Service issues a Fire Weather Watch, Red Flag Warning or High Wind Warning, and those prohibitions run from midnight to midnight on the alert day. Per Boulder County, anyone whose burn escapes and causes damage may face arrest and civil penalties.
How residents should respond
Officials are urging residents to postpone any planned burns, keep yard debris and equipment away from buildings, and avoid welding, mowing in dry grass or other spark-producing tasks until the watch ends. The National Weather Service also suggests securing loose outdoor items and keeping an eye on local forecasts and official county notifications for updates, according to NWS Denver/Boulder.
Residents who want county alerts can sign up through the sheriff’s office website, which posts up-to-the-minute advisories and safety tips, according to the Boulder County Sheriff's Office. The county fire page lists official restrictions and permit rules for anyone who needs to double-check what is allowed.
