Late yesterday afternoon, it started raining hard over much of southeast Michigan.
When it finally let up over 3 hours later, a record-breaking 4.57 inches of rain had fallen at Detroit Metro Airport. Some spots got even more.
According to WDIV meteorologist Paul Gross, it was “one of the heaviest single rainfall totals in Detroit weather history.”
The National Weather Service had anticipated heavy afternoon showers, and warned of possible flooding in some areas.
But the storm that materialized took everyone by surprise. “Back in the area where the rain had ended, a second batch of even heavier rain developed out of nowhere and parked itself right over the heart of the metro area," Gross said.
The storm ended up dumping tons of rain across the heart of Metro Detroit right at the start of rush hour.
