1,237 first-hand accounts of flood events in Arizona, ranked by impact. Each is a NOAA-written narrative of the moment.
Abundant moisture (1.8-2.0) and an unstable environment (MUCAPE 2,000-4,000 J/kg) across south-central and southwest Arizona allowed for convective development to become strong to severe.

Read the full account →As the region transitioned out of the monsoon, a compact low created a high shear - modest CAPE environment. Parameters were sufficient for supercell development and a few supercells did develop amongst isolated to scattered storms in the afternoon across South-central Arizona,…

Read the full account →Strong to severe thunderstorms developed in an unstable atmosphere in the afternoon of the 22nd. Storms initially developed over the high terrain of northern and eastern Arizona as well as near the Table Top mesa area south of Phoenix.
Read the full account →Thunderstorms developed across southeast Arizona in the afternoon, with strong cells pulsing up over terrain features and outflow boundaries. With precipitable water values near record levels for early-July and very slow steering flow, storms were capable of producing very heavy…
