    Temperatures in the triple digits are expected in some parts of the inland valley on Tuesday – likely the hottest day of the week – prompting heat advisories and a Spare the Air alert.

    The National Weather Service issued the heat advisory from 11 a.m. to 7 p.m. – and again on Wednesday, too - as the mercury could climb as much as 20 degrees “above seasonal averages.”

    For example, it might rise to 96 degrees in the East Bay and San Francisco, 98 in the North Bay and 106 degrees in the Tri-Valley area in Contra Costa County.

    The hottest spots are expected to be the interior valleys, San Francisco, the Santa Cruz Mountains and the Monterey Bay region.

    A Spare the Air alert is also in effect for Wednesday, as the air quality is expected to be more polluted. Tuesday marks the fifth such alert this summer, the last one was on Aug. 17.

    In all, 1996 had the most number of Spare the Air alerts with 25 issued that year, 1995 had 24 alerts issued and 1993 had 19 alerts.

    In 2014, there were 10 alerts in all.
