* TEMPERATURES...100-106 degrees, warmest on Tuesday. Overnight

inside vehicles, even if the windows are partially open, can
quickly rise to life-threatening levels.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Never, ever, leave people or pets in enclosed vehicles, even for
a short period of time.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.
