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.
