Special Weather Statement Statement as of 2:40 PM PDT on May 12, 2008

... Watch out for hot temperatures and cold water later this week...

An unusually strong high pressure ridge will build into northern
California by the middle of the week and persist through the
weekend. High temperatures will be as much as 20 degrees above
seasonal normals by Thursday throughout northern interior
California... with some near record or record temperatures possible.
Maximum temperatures in the Central Valley and Delta Region could
soar to around 100 degrees by Thursday while the foothills...
northeast plateau... and lower portions of Lake County may reach the
upper 80s and 90s. Even at 6000 feet in the mountains some areas
will creep into the 80s.

Temperatures in the 80s can cause heat fatigue with prolonged
exposure or physical activity. As temperatures increase... heat
exhaustion and heat cramps become likely and heat stroke is
possible... especially for people who are sitting in full sun
drinking alcohol for hours on end or who are involved in rigorous
physical activity.

All heat-related illnesses are preventable. Common techniques for
beating the heat include taking cooling breaks until you feel
rested... drinking plenty of water... and avoiding physical exertion
during the hottest hours of the day.

At the same time... rivers and streams will be running quickly with
cold water... due to recent snowmelt. This will cause lower
elevation reservoirs... rivers and streams to have dangerously cold
water. Therefore... the combination of the high temperatures and
this cold water can create dangerous situations. People
wading... rafting or fishing in these cold waters become victims of
the cold water every year... either through hypothermia or drowning
in fast-moving water.

Water temperatures in the 40s and 50s can bring on a sudden loss of
body temperature. This is called hypothermia. The expected time
before exhaustion or unconsciousness sets in for a healthy adult may
be as little as 30 to 60 minutes. Hypothermia normally occurs
faster in children than adults.
