1226 PM PDT Wed Jul 3 2024
...EXCESSIVE HEAT WARNING NOW IN EFFECT UNTIL 11 PM PDT
WEDNESDAY...
* WHAT...Dangerously hot conditions with temperatures in the
upper 90`s to 115F expected. Limited overnight relief with low
temperatures in the mid 60s to low 80s. Resultant widespread
Major HeatRisk, with areas of Extreme HeatRisk.
* WHERE...Marin Coastal Range, Sonoma Coastal Range, North Bay
Interior Mountains, North Bay Interior Valleys, East Bay
Interior Valleys, Santa Cruz Mountains, Santa Clara Valley,
Eastern Santa Clara Hills, East Bay Hills, Southern Salinas
Valley, Santa Lucia Mountains and Los Padres National Forest,
and Mountains of San Benito and Interior Monterey.
* WHEN...Until 11 PM PDT Wednesday.
* IMPACTS...Most individuals will be at risk for heat-related
illnesses without effective cooling or adequate hydration,
especially with prolonged outdoor exposure. Without effective
cooling and/or adequate hydration, heat-related illnesses
including heat stroke will be a risk to everyone. Overnight
lows will warm as well leading to poor relief from the heat
specifically in elevated terrain and interior areas.
* ADDITIONAL DETAILS...An exceptionally dangerous situation is
expected to unfold during this potentially historic and deadly
heat event. Several days of temperatures well above normal
will lead to compounding effects among people and
infrastructure, with the possibility of numerous heat related
fatalities. It cannot be stressed enough that while one day at
these temperatures may be manageable for some, an event of
this scale, magnitude, and longevity will likely rival
anything we`ve seen in the last 18 years. Heat is the number
one weather related killer in the United States. By this
weekend, it is VERY LIKELY that we add to that statistic if
preparations are not taken seriously.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Drink plenty of fluids, stay cool, stay out of the sun, and check
up on relatives and neighbors.
Beat the heat and check the backseat! Do not leave young children
and pets in unattended vehicles. Car interiors will reach lethal
temperatures in a matter of minutes.
Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to the early
morning or evening. Take action when you see symptoms of heat
exhaustion and/or heat stroke.
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 9 1 1.
