A thunderstorm hit hillsides scarred by wildfire in Larimer County earlier this week. It caused a flash flood that raced through Poudre Canyon and killed at least one person.

For more on flash floods - and how to stay safe -- we spoke with meteorologist Paul Schlatter of the National Weather Service.
