The National Weather Service in Phoenix has issued an

* urban and small stream flood advisory for...
central Maricopa County in south central Arizona...
this includes the cities of... Tempe... Sun Lakes... Mesa...
Guadalupe... Gilbert... Gila Bend... Chandler...
northwestern Pinal County in south central Arizona...
this includes the cities of... Superior... Florence Junction...
Florence... Coolidge... Casa Grande... Apache Junction...

* until 1030 PM MST

* at 833 PM MST National Weather Service radar indicated
thunderstorms developing south of a line from Gila Bend toward
downtown Phoenix and on toward Superior. Rainfall rates of two to
three inches per hour or more will be possible with the heaviest
storms. A spotter recently reported a half inch of rain in ten
minutes in southeast Chandler. The heavy rainfall will result in
widespread street flooding and washes running across southeast
Maricopa and northwest and north central Pinal County.

Most flood deaths occur in automobiles. Never drive your vehicle into
areas where the water covers the roadway. Flood waters are usually
deeper than they appear. Just one foot of flowing water is powerful
enough to sweep vehicles off the Road. When encountering flooded
roads make the smart choice... turn around... dont drown.

Excessive runoff from heavy rainfall will cause elevated levels on
small creeks and streams... and ponding of water in urban areas...
highways... streets and underpasses as well as other poor drainage
areas and low lying spots.

Do not underestimate the power of flood waters. Only a few inches of
rapidly flowing water can quickly carry away your vehicle.

... .showers and thunderstorms expected during the Labor Day weekend
over southeast California... southwest and south-central Arizona... .

The monsoon is poised to swing into high gear later this week... as an
approaching Pacific low pressure system will draw Mexican moisture
northward into the area... and then produce a significant increase in
showers and thunderstorms over the Labor Day Holiday weekend.

Scattered showers and thunderstorms are forecast to develop over
southeast California... southwest and south-central Arizona Saturday
afternoon and evening... and locally heavy rainfall is possible with
the stronger thunderstorms. As the low pressure system approaches
from the northwest Sunday... the focus for strong and possibly severe
thunderstorms will shift into south-central Arizona where chances for
rain will increase to around 5o percent.

The most significant weather will likely occur over south-central
Arizona... including the greater Phoenix metropolitan area... Sunday
afternoon and evening. The stronger thunderstorms have the potential
to produce very heavy rainfall with localized flash flooding...
strong winds in excess of 60 mph... moderate hail and deadly cloud to
ground lightning. In addition... much cooler weather is expected
Sunday as high temperatures will likely lower to well below seasonal
normals.

Showers and thunderstorms will decrease from the west on Labor Day as
drier and warmer air spreads in from the west. There will still be a
chance for afternoon and evening thunderstorms... mainly over the
higher terrain east of Phoenix.

Stay up-to-date on the latest forecasts by listening to weather radio
on the public service band. More detailed information is available

A Flash Flood Warning has just been issued for a portion of
south-central or southwest Arizona... or far southeast California.
Please follow these safety rules if flash flooding or severe weather
threatens your area.

Area residents should monitor flood conditions... and be prepared to
move to higher ground should flood waters threaten. If flash
flooding is observed... act quickly. Do not stay in areas subject to
flooding when water begins to rise... especially normally dry washes.

Be especially cautious at night when it is harder to recognize the
dangers of floods and flash floods. It is very difficult at night to
tell how much water is on roads. Motorists should not drive through
water of unknown depth.

Do not drive your vehicle into areas where water covers the roadway.
The water depth may be too great to allow your car to cross safely
and the Road beneath may not be intact. Vehicles caught in rising
water should be abandoned quickly. It only takes a foot or two of
flowing water to wash most cars away.

Remember... most deaths in flash flooding occur in automobiles. Do
not attempt to cross bridges... dips... or low water crossings if
water covers the roadway. Never try to cross a flowing wash... even
a small one... on foot. Do not drive around barricades. If your
vehicle stalls... abandon it immediately and seek higher ground.

During heavy rains... keep children away from storm drains... water
catchments... and washes. Shallow... gently flowing water can become a
raging torrent in a matter of minutes.

A sudden downpour may cut visibility to near zero. Wind-driven rain
may hamper both driver and pedestrian. When faced with such weather
conditions... be especially cautious and proceed slowly within your
range of sight.

Hikers and campers should immediately climb to higher ground when a
warning is issued for the area or when flooding is observed.
