Lightning lit up the Denver skies Monday night, bringing a late evening rainstorm across the metro area.
Depending on the location, between a quarter inch and 0.7 inches of rain fell in Denver, according to the Community Collaborative Rain, Hail and Snow Network. Heavier downpours weren't far away, with Castle Rock getting up to 3 inches of rain, as well as intense hail.
While last night's rain didn't cause major flooding within Denver, the possibility will remain through Tuesday and likely the rest of the week. The Colorado Water Conservation Board has issued an alert of a moderate flooding risk for residents in a dozen northwestern Colorado counties, including the Denver metro.
"Another round of heavy rain producing thunderstorms can be expected again this afternoon and evening," the National Weather Service said. "Stronger storms will be capable of producing 1.5 to 2 inches of rain in 45 minutes or less."
Heavy rains are expected to start after 3 p.m..
Flooding is most likely to occur in low-lying areas, like near rivers, creeks and streams. Streets with poor drainage are also prone to flooding. Safety officials say drivers should never drive through flooded roads.
