chronic ailments. Additional societal impacts due to people
seeking relief by traveling from hotter inland areas to cooler
coastal areas.
* ADDITIONAL DETAILS...Daytime temperatures for inland areas are
forecast to range from the 90s to 104 on the hottest days of
Tuesday and Wednesday. The San Francisco Bay shoreline and
Santa Cruz County coast could warm to the upper 80s and lower
90s during these hottest days. For San Francisco itself, the
Downtown/Bayside could warm to the lower 80s while the Pacific
coastal side will peak in the mid 70s. Other coastal areas
should remain relatively mild (70s to around 80) compared to
inland areas given light onshore flow. Significant temperature
differences from the coast to a few miles inland could drive
an excessive number of persons towards the coast to seek
relief from the heat. Individuals are advised to check with
local authorities on potential closures of parks and beaches
and be aware of any special requirements for visiting such
areas. Overnight lows will range from the upper 50s to mid 60s
which may limit the amount of typical overnight relief from
the heat.

Information:
Drink plenty of fluids, stay in an air-conditioned room, stay out
of the sun, and check up on relatives and neighbors. Young
children, disabled or elderly adults, 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.
