Peoria was inside a National Weather Service flood watch<\/a> that ran from Wednesday afternoon, October 21, through Thursday afternoon, October 22. The watch named Peoria and said localized rainfall rates of 1 to 2 inches per hour were possible. A watch is a heads-up that flooding could develop. It is not a report that it did.<\/p>\n

So far, the rain in Peoria has been light. Flood Control District of Maricopa County gauges in Peoria<\/a> recorded 0.00 to 0.08 inches in the 24 hours ending 5 a.m. Thursday. October totals at the city’s neighborhood gauges, from Grand Avenue north to Vistancia, ranged from 0.28 inches to 0.59 inches. These are preliminary figures, posted while the watch was still in effect.<\/p>\n

Why a flat roof still deserves a look<\/h2>\n

If your Peoria home has a flat or low-slope section, such as a foam roof over a patio, addition or garage, it depends on water reaching a drain or scupper. This week’s severe thunderstorm warnings<\/a> for Peoria also described 60 mph gusts, and wind moves leaves and debris onto roofs. A light rain is a good time to see where water collects before a heavier one arrives.<\/p>\n
