The Community Collaborative Rain, Hail, and Snow (CoCoRaHS) project is really interesting. It is a nearly-nationwide collection of volunteers who take daily measurements of the precipitation they receive. I participate because my meteorological education has taught me that there’s always a need for more data. The side benefit is that I get to see what others around me have received in the way of falling moisture. The differences across small distances can be pretty large sometimes (although I suspect that is often due to a poor rain gauge setup), but seeing similar numbers can help you believe that you really did get that much rain.
Case in point: since Tuesday, my station has recorded 4.56″ of rain. To put that in perspective, the average rainfall for the month of May is 3.93″. On Wednesday, when I recorded 2.03″, I might not have believed it had other stations nearby not recorded very similar values. Today’s 2.35″, on the other hand, was pretty believable on it’s own. The lake that is my yard spoke volumes.
Last weekend, my wife and I hauled, mixed, and poured 3,200 pounds of concrete. Why? Because the walkway that goes from our front porch to our driveway sat lower than the ground around it, meaning when it rained, your shoes got wet. I’m very grateful we got it finished, since when we got home from a friend’s house last night, our yard was a marsh. Even now, over 12 hours after most of the rain has stopped, the ground just has nowhere to put the water.
As a result of all the rain, the Wabash River has gone from 6 feet to 16 feet since 8 AM Wednesday, with a forecast crest of 20 feet at 8 PM tonight. At 20 feet, Extensive flooding increases. Flood waters begin to cover Stair Road located on the southeast side of the river just off SR 225 in NE Tippecanoe County. Low portions of Barton Beach Rd is flooded. Several river residences are nearly isolated by high water. River residences near Interstate 65 are affected by high water. River Road near Wabash Valley Hospital floods. Local roads begin to flood in the Granville Bridge area. River residents become concerned.
