In Santa Clara Valley the National Weather Service has issued a heat advisory from noon to 8pm. The advice from the County Health Department is stay cool and stay inside, if possible. Triple digits are expected in the region's typically hottest cities.
For those needing help staying out of the summer heat, many cities around the Bay Area are opening community cooling centers to the public. In San Jose, these centers will be open from noon to 8, the same hours of the area's heat advisory. Public health officials urge people, especially the elderly, children and the sick, to drink plenty of water and stay out of the heat and the bad air.
Advisories have been issued about the unhealthy air quality in the region; it will be most smoggy in the South Bay and moderately poor air in the East Bay.
The Bay Area Air Quality Management District warns that vigorous exercise should only be done in the early morning hours when ozone concentrations are lower.
This is the tenth time the health advisory has been issued this season and the second consecutive Spare the Air Day; while people are urged to drive less and use public transportation, Bay Area transit agencies are not offering free rides.
