Storms that flooded several Phoenix-area freeways and numerous local streets during the Monday morning commute set an all-time record for rainfall in Phoenix in a single day.
The National Weather Service recorded 2.99 inches of rain by about 7 a.m., breaking the old record of 2.91 inches set in 1933.
The Monday morning rainfall also eclipsed Phoenix’s average total rainfall of 2.71 inches for Phoenix’s entire summer rainy season.
A flash flood warning was issued for most of the Phoenix area and its outskirts through late Monday morning because of heavy thunderstorms and showers. Flash flood watches cover most of the rest of Arizona.
Sections of the major commuter freeways Interstate 10 and 17 in west Phoenix were closed during the commute.
