The secondary rain gauge (Davis Vantage) measured peak rate of 11.97 inch/hour at 2100hrs. This was the first 24 hour rainfall of >3/4" in more than two weks. Since the ppt was concentrated in such a short time, there was high runoff. Although no significant effects are in visible range, I expect sloped portion of driveway will have usual "high runoff" ruts.
