Red Flag Warning and Heat Advisories in Effect Across Northern Colorado

Dangerous Fire Conditions and Extreme Heat Expected Through Friday

LARIMER COUNTY, Colo. — The National Weather Service has issued multiple Red Flag Warnings and Heat Advisories across Northern Colorado and surrounding regions through Friday, August 8.

Excessive Heat
