Heat Advisory
Statement as of 2:43 PM PDT on July 8, 2008


... Heat advisory in effect until 11 am PDT Friday...
... Excessive heat watch no longer in effect...

Very warm weather is forecast to continue to effect San Francisco
through Friday morning of this week. High temperatures in the
city are expected to warm a few degrees from today which would
produce highs well into the 80s in many neighborhoods and to near
90 in some of the warmest parts of the city near the downtown. Some
relief is expected by Friday afternoon as slightly cooler weather
returns to the area.

As a strong ridge of high pressure remains overhead hot weather
can be expected to continue across the Santa Clara Valley. Highs in
many areas for Wednesday and Thursday will be in the upper 80s to
upper 90s while overnight lows in many places will only cool off
to between 65 and 70 degrees. The combination of the very hot daytime
temperatures and warm conditions at night will make for
potentially dangerous conditions. Some relief is expected by
Friday afternoon as slightly cooler weather returns to the area.

This heat advisory is being issued utilizing a new heat health
warning system. It is specific to the areas included. It is
targeted at the elderly... or infirmed... who might be much more
sensitive to heat and thus at greater risk. Individuals who fall
into this category should be especially careful by drinking plenty
of water... reducing outdoor exposure... staying out of the
sun... seeking a cooler location for the day if no air
conditioning is available in the living quarters... and/or asking
a friend or relative to check on you frequently. For more
