How much water falls during a storm?
Maybe it is the middle of July in Georgia and both you and your tomatoes are wilting in your yard, both looking to the sky and hoping for rain. Or maybe a low-pressure cell has been napping overhead and your arm is hurting from holding that umbrella while you watch your basement fill up with water. Either way, you would like to know how much rain has fallen—how many gallons have come down from the skies onto your roof, yard, block, or town.
And, of course ... how many baths could you get from your rainstorm?
In the form below, choose an area(s) and a rainfall amount—then it will tell you how many gallons of water fell from the sky onto that area. I think you'll be surprised as to how much rain really does fall in a rainstorm.
