The National Weather Service in Boulder has issued a Flash Flood Watch for parts of the Front Range Foothills, (green area on map) until Saturday night.
-Thunderstorms are expected Friday and Saturday afternoon. A few storms may have heavy rainfall, which will increase the chance of localized flash flooding, especially in burn scar areas.
-Several people have already perished in flash floods this summer, so please take this seriously.
