Extremely heavy rainfall from around sundown Thursday through this morning has prompted a flash flood warning for a band of the metro area that includes Lake Lotawana and the areas south of Blue Springs, Grain Valley and Oak Grove. In Greenwood, almost 5 inches of rain has been recorded since 8 p.m. Thursday.
The National Weather Service at 10:18 this morning posted a flash flood warning for a thin rectangular area that stretches from Olathe, Kan., east to the northeast corner of Johnson County, Mo. That area chiefly covers the Lee’s Summit area in Eastern Jackson County but also angles slightly to the north to come to the edge of Oak Grove. The warning is in effect until 3 p.m. In addition, there’s an urban and small-stream advisory until 2:30 p.m. for southwestern Jackson County, northwestern Cass County and southern Johnson County on the Kansas side.
Authorities remind drivers never to drive through standing or moving water.
