1,237 first-hand accounts of flood events in Arizona, ranked by impact. Each is a NOAA-written narrative of the moment.
Isolated showers and thunderstorms initially began across parts of southern Gila County, along with eastern Maricopa County and northeast Pinal County, producing locally heavy rainfall leading to isolated flash flooding.
Read the full account →A very moist (PWATs 2.0+ inches) and unstable (MLCAPE 2000-3000 J/KG) air mass led to be a very conducive environment for vigorous thunderstorm activity across portions of southwest Arizona.
Read the full account →The combination of near record moisture content (PWATs 1.8-2.0 inches), moderate to strong instability (SBCAPE 2000 J/KG), very slow steering flow and an upper-level disturbance resulted in a very conducive environment for the generation of thunderstorms producing very heavy…

Read the full account →A mid-level high pressure was situated across southern Nevada, with the local area under an northeasterly flow regime. At upper-levels, a disturbance moving northward out northern Baja California resulted in a diffluent flow, favorable for vertical ascent.
