* TEMPERATURES...Thursday high temperatures are forecast to range
from 98 to 108 degrees across most inland areas with locally
hotter temperatures possible. The immediate coast will mostly be
spared from the heat. 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. Temperatures will cool by 5 to 10
degrees on Friday...but still warm enough to present heat risks
to the population.

* Thursday High Temperature Ranges: 98-108F (locally to 112F).

* Friday High Temperature Ranges: 92-102F (locally up to 105F).

* 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.
