9/12/2013 7:00 AM 8.87 M M M M About 9 last night I measured 2.71" since 7am 9/11. By 1:40 am 9/12, and additional 4.91" had fallen and another 1.00 in the remaining hours of the night. Torrential, unremitting rain, like a tropical storm. Addendum: 10/27; On 9/12 I measured different catches in my two gauges: 8.62 and 9.12. I chose the lower of the two, thinking there couldn't possibly have been more rain than that, but of course this was no ordinary storm. After significant disruption in my life - directly flood related - here is what I've decided. I've consulted the experts, I've examined NCAR archived data, I performed a crude experiment to see whether the gauge with the larger reading might have been favored by splash from the pavement and I've concluded there is no reason to favor one reading over the other. The amended reading reported here shows the average of the two, adding 0.25" to the original 8.62"
