Flash flooding caused by excessive rainfall is possible in creeks, normally dry washes, swimming holes and over recently burned areas. Low-water crossings may be flooded.

An upper-level trough will bring a deep surge of subtropical and tropical moisture into the region. Showers and thunderstorms will develop across much of Northern and central Arizona early Wednesday morning, Oct. 21, and continue through Thursday evening. Stronger thunderstorms will bring threats of flash flooding, while more prolonged rainfall could lead to elevated flow in streams, rivers and washes.

Residents should have a way to receive flash flood warnings and be prepared to take action should warnings be issued. Additional information is available at weather.gov/flagstaff.
