Excessive Heat Warning issued July 2 at 11:36AM PDT until July 9 at 11:00PM PDT by NWS San Francisco CA
* 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 next Tuesday, July 9.
* 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 over the next week as we enter a 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.
Drink plenty of fluids, stay in an air-conditioned room, stay out
of the sun, and check up on relatives and neighbors. Young
children and pets should never be left unattended in vehicles
under any circumstances.
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 lightweight and loose fitting clothing when
possible. 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.
