A flash flood warning issued by the National Weather Service covers Scottsdale, Phoenix, and Paradise Valley through 9:30 p.m. MST Wednesday, as monsoon storms push across Arizona and more activity is forecast into early Thursday.
NWSPhoenix posted on X that the warning encompasses all three communities. The azfamily.com weather alerts page notes that storms carrying abundant monsoon moisture are capable of producing 1 to 2 inches of rain in less than an hour, conditions that produce rapid flash flooding in area washes, creeks, and rivers.
The National Weather Service in Tucson separately issued a flash flood warning for North Central Pima County in southeastern Arizona, according to azcentral.com, with that warning in effect until 9 p.m. MST. Doppler radar at the time of issuance indicated heavy rainfall already moving through the affected area.
12News reports storms are moving through the state while the Valley will see more activity Wednesday night and early Thursday.
Residents and property owners in low-lying areas and near washes should monitor NWS Phoenix updates through early Thursday morning.
