How much more rain will we get?
The rain isn't over. Friday night was just the beginning of the weekend rains with another inch or two of rain expected through Sunday evening.
Detroit could get another 1.42 inches of rain - on top of the 5 to 6 inches of rain already received. Ann Arbor could literally be in the same boat with another 1.78 inches of rain expected.
Pontiac is looking at an inch while Mount Clemens is less than an inch.
How much is an inch of rain?
One inch of rain over one square mile is equal to over 17 million gallons of water.
So if you double that, Oakland and Macomb Counties are both in the 34 million gallons of water range…in ONE SQUARE MILE!
Now, look at Wayne County, where you take 17 million gallons - but times 6. That's 102 MILLION GALLONS OF WATER per square mile. There are over 142 square miles in Detroit.
And more rain is on the way.
