Excessive Heat Warning

URGENT - WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
1024 AM PDT Thu Jun 22 2017

...Extended period of very hot temperatures expected across
interior portions of southwest California through this weekend...

.Strong high pressure over Arizona will continue to bring very
hot weather in many parts of interior southwest California
through the weekend. The hottest temperatures are expected to be
in the Antelope Valley with highs between 105 and 110 degrees
each day. The Excessive Heat Warnings were extended through
Sunday evening for the Antelope Valley and the Los Angeles County
Mountains.

Heat advisories remain in effect for the Santa Barbara and Ventura
County mountains as well as the Cuyama Valley as hot temperatures
will continue during the day with limited overnight relief.
However, due to an increase in the onshore flow at lower
elevations the heat advisory has been cancelled for the Santa
Clarita Valley. It`s possible that heat advisories may need to be
expanded Saturday to cover additional valley areas as temperatures
are expected to increase.

1024 AM PDT Thu Jun 22 2017

...EXCESSIVE HEAT WARNING REMAINS IN EFFECT UNTIL 9 PM PDT
SUNDAY...

* TEMPERATURES...100-105 degrees across lower elevations. Night-
  time temperatures in the 70s to around 80 degrees will be
  common.

* IMPACTS...The very high temperatures will create a dangerous
  situation in which there is an increased threat of heat
  related illnesses. Temperatures inside vehicles, even if the
  windows are partially open, can quickly rise to life-
  threatening levels. The extended heat wave will also bring
  elevated fire danger through the weekend, with critical fire
  weather conditions on Thursday.

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.
