Hot and humid weather will be common for the next several days as
high pressure aloft builds over the area. Afternoon heat indices
will climb into the 105 to 110 degree range each day with
nighttime low temperatures only falling into the mid to upper
70s. Isolated thunderstorms will be possible over the next couple
of days and may provide some temporary local relief from the heat
in few places.

Precautionary/preparedness actions...

A heat advisory and an excessive heat watch means that a period
of hot temperatures is expected. The combination of hot
temperatures and high humidity will combine to create a situation
in which heat illnesses are possible. Portions of the watch area
will likely be upgraded to an excessive heat warning later today.

Strenuous activities should be reduced... eliminated or
rescheduled to the coolest time of the day. If you must be
outside... drink plenty of fluids to avoid dehydration. Your body
can lose up to a gallon of water an hour through perspiration.
Alcoholic and caffeinated beverages or beverages with a high
sugar content... can increase the rate of water loss in your
body... increasing the risk of heat exhaustion or stroke. Wear
lightweight... light-colored ... loose-fitting clothing. Wear a hat
to shield yourself from the sun... and use a sunscreen to reduce
possible sunburn.

The heat index is a measure of how hot it feels when the affects
of humidity are combined with the temperature. A heat index of
105 degrees is considered the level where many people begin to
experience extreme discomfort or physical stress. The heat index
is measured under shady conditions... and direct exposure to
sunlight can increase the heat index as much as 15 degrees.

Never leave anyone in a closed... parked vehicle... temperatures
inside can reach over 150 degrees quickly... resulting in heat
stroke and death. Children... the elderly... and people with
chronic ailments such as heart disease or high blood pressure...
are usually the first to suffer from the heat. Heat exhaustion...
heat cramps... or in extreme cases... heat stroke may result from
prolonged exposure to these conditions. Friends... relatives... or
neighbors should check on people at risk... especially those
without air conditioning.
