May 11-13, 2018 Long Duration Rain Event

Overview

A frontal boundary that stalled south of Michigan allowed repeated rounds of rainfall to move across the region from May 11 to early May 13, 2018. The heaviest axis of rain fell across the I-696 corridor with locations seeing anywhere between 1.5" - 3.5" of accumulation. Impacts included several road closures across Oakland County down into Wayne County due to localized flooding. Additionally, the Rouge River in Southfield/Detroit and Clinton River near Clinton Township quickly reached minor flood stage, impacting communities and roadways along the rivers.

48 Hour Radar Derived Precipitation Estimates

* Note that NWS DTX's radar had an unexpected outage from May 12, 131 PM - 635 PM, thus rainfall estimates were not accumulated during this time. Additionally, unusually high estimates located along the Lake Huron shoreline from St. Clair County up to Sanilac County were artificially inflated due to ground clutter, and do not represent rainfall estimates across that area. *
