1,237 first-hand accounts of flood events in Arizona, ranked by impact. Each is a NOAA-written narrative of the moment.
A weak upper level disturbance combined with abundant moisture approaching 2 inches of precipitable water to generate widespread thunderstorms across southeast Arizona. Thunderstorms produced flash flooding and some produced damaging winds.
Read the full account →Moderate to heavy rainfall amounts were reported over two days after a plume of subtropical air moved into Arizona. The heaviest amounts occurred over the higher terrain generally east and north of Phoenix, resulting in flooded roads and other low-lying areas.

Read the full account →A potent upper-level low pressure system situated across southern California transported a plume of deep subtropical moisture across the Desert Southwest, with PWAT values peaking as high as 1-1.2 across portions of southern Arizona.
Read the full account →A deep closed low along the California coast and broad upper level ridging centered over the southern Plains promoted deep southerly flow across the Desert Southwest.
Read the full account →An upper-level low pressure system situated near the northern Baja Peninsula aided in bringing in abnormally high moisture content into south-central and southwest AZ. Precipitable water values of approximately 1 were observed, which for mid-May is a record.
Read the full account →The overall pattern featured an upper-level low pressure situated along the west coast and the subtropical high pressure centered over New Mexico. This overall pattern configuration resulted in southerly flow across Arizona, which helped transport moisture into the region.
