Watches & Warnings

Excessive Heat Warning
Issued: 3:38 AM PDT Jun. 22, 2017 – National Weather Service

... Excessive heat warning remains in effect until 9 PM PDT this
evening...

An excessive heat warning remains in effect until 9 PM PDT this
evening.

* Temperatures... high temperatures are forecast to range from 90
to 108 degrees across most inland areas with locally hotter
temperatures possible. Overnight cooling will provide some
relief but nighttime lows are forecast only to drop into the
upper 50s and 60s for most inland areas. For communities in
the thermal belt at higher elevations, expect warmer overnight
lows in the lower to mid 70s.

* Thursday high temperature ranges: 98-108f (locally up to 110f).

* Impacts... prolonged exposure to these temperatures will
increase the risk of heat related illnesses, particularly for
vulnerable populations such as the elderly or infirm. Pets and
livestock may also require extra care through the warm
weather. Individuals heading to the coast for heat relief and
unfamiliar with the ocean may be at increased risk of
hypothermia or being pulled out to sea by rip currents. Hot,
dry weather will increase risk of human sourced wildfire.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The hot weather will
create a dangerous situation in which heat illnesses are likely.
Drink plenty of fluids... stay in an air-conditioned room... stay
out of the sun... and check up on relatives and neighbors.
