Remnants from a tropical storm that dropped a record amount of rain in Phoenix area now are headed to Colorado and Utah.
A separate flash-flood warning was issued through Thursday morning for Yavapai County north of Phoenix because of possible thunderstorms.
National Weather Service meteorologists say a record 2.35 inches (5.97 centimeters) of rain fell at Phoenix Sky Harbor International Airport as of Tuesday night.
That made it the rainiest October day since records have been kept, topping the 2.32 inches (5.89 centimeters) recorded on Oct. 14, 1988.
Meanwhile, a 22-foot-high earthen dam in southern Arizona that had been at risk of breaking and flooding a small village held steady Wednesday. The lake behind the dam receded after being swollen with runoff from the remnants of Tropical Storm Rosa.
