Northwest Maricopa County Excessive Heat Watch Statement as of 5:52 am MST on July 10, 2009

... Excessive heat watch in effect from Saturday morning through
Sunday evening...

The National Weather Service in Phoenix has issued an excessive heat
watch... which is in effect from 10 am Saturday morning through 8 PM
Sunday evening.

Strong high pressure aloft centered over West Texas will expand and
strengthen over the southwest United States during the next couple of
days... bringing the hottest temperatures so far this year. Forecast
highs over the Lower Desert will range from 109 to 115 degrees
Saturday... and from 110 to 117 degrees Sunday. The heat index is
forecast to reach or exceed 105 degrees for at least several hours
each afternoon. The forecast high temperature at Phoenix Sky Harbor
Airport is 112 degrees on Saturday and 113 degrees on Sunday... with
an overnight low of 89 degrees Saturday night.

Precautionary/preparedness actions...

It would be wise to complete as much outdoor activity as possible in
the early morning when the sun and heat are less intense. During
periods of excessive heat... individuals can suffer heat-related
illness when the body can no longer cool itself. If you plan to be
outside for an extended period of time in the afternoon or early
evening... stay in the shade as much as possible and drink abundant
amounts of water. Wear light-colored and loose-fitting clothing. If
you wear a wide-brimmed hat... your head and body will be much cooler.
Stop outdoor activities... drink lots of water or other non-alcoholic
beverages... and if possible... spend more time in air-conditioned or
well-ventilated places.
