No flooding spill-over to street, however the creek did rise slightly above its (engineered) banks. The remainder of the rain fell overnight with much less fanfare.

8/21/2018 6:00 AM 2.60 M M M M *Edited: emptied rain-gauge half-way through the day and forgot to add together the 1.4" and 1.2". Given how far off this is from local readings, I'm inclined to doubt the accuracy, but at the same time, the street never flooded to the degree that it usually does when we have insanely heavy rain--it stayed at least six inches below the threshold of putting the street underwater.

9/18/2018 7:00 AM 0.08 M M M M Rain began after 10 p.m. High winds in the middle of the night were strong enough that a tall tree in the wood fell over; however, many of these trees have suffered from flooding that leaves their roots nothing solid to hold to, and there are standing dead trees. (Have not gone out to check which tree it was.)
