...Hydrologic Outlook for the State of Arizona...

Snowmelt alone is not expected to cause flooding across Arizona this
spring.

In general seasonal precipitation to date has exceeded one hundred
percent of normal over much of the State.  Soil moisture conditions
as modeled by the Colorado Basin River Forecast Center are near or
above average in most of the Salt, Verde, and Gila River Basin.
Reservoir conditions on the Verde River System approach 98 percent
full and the Salt River System are near 65 percent full.  Above
median streamflow occured in the Gila, Salt, and Verde Basins in
February due to greater than normal amounts of precipitation on
moist soils and snowpack.

Any other storms moving through this March will be efficient for
runoff generation.  Runoff for much of this spring should be above
normal in particular over central and northern Arizona.

Snowmelt alone rarely results in flooding within the State.  Rain
falling on a snowpack is typically needed to result in flooding.
Snowmelt this spring may result in inundation of low lying areas
close to mountain streams and creeks but flood impacts are not
anticipated and should be minimal.

The long range three-month outlook provided by the Climate
Prediction Center slightly favored below normal precipitation and
above normal temperatures across the State.
