Kansas City and the surrounding metropolitan area remained under a flash flood warning until 3:15 a.m. Sunday as storms moved across the region late Saturday night, dropping heavy rain and knocking out power for thousands.
The National Weather Service issued a flash flood warning that includes Wyandotte, Leavenworth and Johnson counties in Kansas and Jackson, Platte, Clay and Cass counties in Missouri.
The weather service, based in Pleasant Hill, Missouri, said the rain is expected to move slowly through the southern and eastern parts of the metro.
Both the weather service and Kansas City Fire Department were warning people via Twitter late Saturday night to avoid driving through flooded roadways as the heavy rain inundated parts of the city.

A flash flood watch that was issued earlier Saturday remains in effect until early Monday morning. According to the weather service, 1 to 4 inches of rain is possible now through late Sunday night as severe weather persists.
A severe thunderstorm watch was also extended for parts of the Kansas City metro until 5 a.m. Sunday.
