Flash Flood — Sep 28, 2019
After a moderate to heavy rainfall event providing 2 to 3 inches just prior to this, the pump was primed so to speak for flooding potential. A generally stationary front resided south of the area into Missouri, but upper level and mid level flow strongly suggested storms would track north of the surface boundary and across portions of southern and central Iowa. The initial wave of rain was init...

The first tornado was on the ground for several miles tracking through portions of Marion, Lucas and Monroe Counties. The second tornado formed just west of Albia and struck the town of Albia damaging several ho...
