Flash flooding in Sabino Creek

Flash floods are triggered by intense rain or rapid snowmelt. This causes a rapid and dramatic increase in streamflow.

Floodwaters can appear quickly from rain upstream, even when no storm is visible in the immediate area. In a matter of minutes, Sabino Creek can go from a trickle to a raging torrent of 25 to 10,000 cubic feet per second or more.

Flash floods can be dangerous, even disastrous, in Sabino Canyon, as well as in washes in metropolitan Tucson.

Be especially cautious hiking in Sabino Canyon during the summer monsoon . If flooding occurs, head away from the streambed to higher ground, and avoid already flooded and high velocity flow areas. Do NOT try to cross bridges with water flowing over them during a flash flood.
