Internal Message Status
Flash Flood Prediction Program

MESSAGES WILL BE ALLOWED TO EXPIRE AT 11:59PM
-Message 1's issued for the entire District will be allowed to expire at 11:59pm, as the threat for heavy rainfall has come to an end.
-It was an active afternoon and early evening across portions of the District, due to an influx of moisture and plentiful upper level support. The atmosphere has largely stabilized at this hour, and thunderstorms capable of heavy rainfall are no longer expected.
-Currently light showers around the Arapahoe County District boundary should quickly taper off as they move into a more stabilized atmosphere. Additional light showers or perhaps a weak thunderstorm remain possible through 2:00am over the District.
STORM RAINFALL POTENTIAL AND DURATION: Showers and isolated thunderstorms will produce rainfall amounts between Trace-0.20" in 10-30 minutes.

WORST CASE SCENARIO: An isolated stronger thunderstorm, or a slow moving moderate rain shower produces up to 0.50" in 45-75 minutes
