Special Weather Statement
Statement as of 4:00 PM PDT on May 16, 2008


... Peak snowmelt into rivers and streams this weekend...

With well above average temperatures this weekend... mountain
snowmelt will be reaching around peak levels for the year. With
water level running high and fast... people swimming or wading can be
easily swept downstream. Even relatively shallow water can be
dangerous. While air temperatures will be hot... water from snowmelt
will be very cold. People wading... rafting or fishing are
susceptible to a sudden loss of body temperature from the cold
water. This condition is called hypothermia and it can be life
threatening.

Over the weekend... temperatures will be 10 to 20 degrees above
normal. Heat related illnesses are possible in these conditions
unless proper precautions are taken. Persons working outdoors or
planning outdoor activities should wear lightweight light-colored
clothing... take frequent breaks from the sun and drink plenty of
non-alcoholic fluids. Try to avoid strenuous activity during the
hottest time of the day. Do not leave children or pets alone in an
unattended vehicle.

Temperatures are expected to return to near normal by mid week.
