National Weather Service Issues Flash Flood Warning, July 2, 2020    5:44 pm

Issued by National Weather Service – Tucson, AZ

The National Weather Service in Tucson has issued a Flash Flood Warning for Northeastern Pima County and Southeastern Pinal County in southeastern Arizona.

Until 845 PM MST.

At 544 PM MST, Doppler radar indicated thunderstorms producing  heavy rain across the northern Catalinas. Flash flooding is  ongoing or expected to begin shortly.

Excessive rainfall over northern portions of the Bighorn burn scar  will result in debris flow. The debris flow can consist of rock,  mud, vegetation and other loose materials.

HAZARD…Life threatening flash flooding. Thunderstorms  producing flash flooding.

SOURCE…Doppler radar.

IMPACT…Life threatening flash flooding of creeks and streams.

Some locations that will experience flash flooding include:

Campo Bonito.

This includes the following streams and drainages:

Catalina Wash, Gibb Wash and Alder Wash.


Move away from recently burned areas. Life-threatening flooding of  creeks, roads and normally dry washes is likely. The heavy rains  will likely trigger rockslides, mudslides and debris flows in steep  terrain, especially in and around these areas.
