Much of the Pikes Peak region was under a flash flood watch Sunday, as monsoonal moisture was expected to fire up thunderstorms, the National Weather Service said.
The watch was put in place at noon Sunday and was expected to last into Monday morning. Forecasters predicted a 70 percent chance of heavy rain in Colorado Springs and over the nearby foothills Sunday, conditions that could drive flooding from the Waldo Canyon and Black Forest burn scars.
The burn scar areas lack vegetation to soak up moisture and have driven a string of muddy floods this summer, including turning parts of Highway 24 west of Manitou Springs into a muddy river last week.
The Weather Service says people in flood-prone areas need to be on their toes this afternoon and be ready to head to higher ground if flooding strikes.
Storms are likely through Monday morning, before they clear off Monday night into Tuesday, forecasters predict. Tuesday is expected to be dry, with chances of thunderstorms increasing through the week.
So far, July, has been wet, with more than a half inch of rain above normal. But drought lingers in the region. Since Jan. 1, Colorado Springs has seen 4.6 inches of rain, well below the 9 inch average.
