As of this morning, the rainfall at Phoenix Sky Harbor International Airport had reached 2.96 inches, setting a record for the most rain in a single day, according to the National Weather Service. (For some perspective: The average rainfall during Phoenix’s rainy season is 2.71 inches.)
How bad is the flooding? Pretty bad:
The area around Phoenix remained under a flash flood warning as of noon (on the East Coast), with flash flood watches across much of the rest of the state. And the deluge isn’t about to let up, as Angela Fritz notes at the Capital Weather Gang.
