... Flash Flood Watch in effect from 11 PM MST this evening
through Sunday afternoon...
The National Weather Service in Tucson has issued a
* Flash Flood Watch for portions of south central Arizona and
Southeast Arizona... including the following areas... in south
central Arizona... southeast Pinal County and Tohono Oodham
Nation. In Southeast Arizona... Cochise County... northern
Greenlee County... Santa Cruz County... Tucson
Metro/Marana/Green Valley and upper Gila River valley.
* From 11 PM MST this evening through Sunday afternoon
* a very moist airmass will be in place across Southeast Arizona
this weekend as the remnants of tropical system Dolly approach
the area from the southeast. Heavy downpours associated with
remnant tropical systems can occur at any time... day or night...
as well as rainfall rates well over one inch per hour. Much of
Southeast Arizona is expected to receive amounts between one
half of an inch to 1.5 inches... with localized amounts of 2 to 5
inches by Sunday evening. These rainfall amounts would result in
at least some flash flood problems.
* Flooding of washes and urban areas are possible.
A Flash Flood Watch means that conditions are favorable for
widespread flash flooding to develop... but has not yet occurred.
Please monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
Be especially cautious at night when it is harder to recognize
the dangers of flash floods. If flash flooding is observed... act
quickly. Turn around and take another Route.
