Statement as of 8:24 PM PDT on October 20, 2017

Expires 11:00 PM EDT on October 24, 2017


... Excessive heat watch remains in effect from Monday morning
through Tuesday evening...

* temperatures... 100-106 degrees on Monday and Tuesday.
Overnight lows in the upper 60s and 70s. Isolated lower 80s
possible in the foothills and mountains.

* Impacts... the very high temperatures create a dangerous
situation in which heat illnesses are possible. Temperatures
inside vehicles, even if the windows are partially open, can
quickly rise to life-threatening levels.

Precautionary/preparedness actions...

Take extra precautions Monday through Tuesday 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.
