  • Excessive Heat Watch for San Fransisco Peninsula Coast County, California
  • Excessive Heat Watch issued June 15 at 4:44AM PDT until June 18 at 11:00PM PDT by NWS
  • Effective: Thursday, June 15, 2017 at 4:44 a.m.
  • Expires: Sunday, June 18, 2017 at 11 p.m.
  • ...Hot Temperatures Inland Friday through at least Sunday...
    .High pressure building over the west will bring a robust warming
    trend and hot temperatures to inland communities Friday through
    Sunday. Saturday and Sunday are expected to be the warmest days,
    with some areas reaching triple digit temperatures and locations
    up to 20 degrees above normal. These increasing temperatures may
    increase heat related illnesses for the young, elderly, or other
    sensitive groups, especially those exposed to prolonged outdoor
    heat. The rapid increase in temperatures may not provide adequate
    time for acclimation to the heat, further increasing risk of heat
    related illnesses in the impacted areas. In addition, pets, crops,
    and livestock may demand extra care through the warm and dry
    weather. Locations along the immediate coast will experience much
    more seasonable temperatures due to the cooling influence of the
    ocean.
    ...EXCESSIVE HEAT WATCH REMAINS IN EFFECT FROM FRIDAY AFTERNOON
    THROUGH SUNDAY EVENING...
    an Excessive Heat Watch remains in effect from Friday afternoon
    through Sunday evening.
    * TEMPERATURE...Above average temperatures will become widespread
    by Friday. Saturday and Sunday are expected to be the warmest
    days of the hot streak, with local temperatures of up to triple
    digits or 20 degrees above normal. Above average temperatures
    continue early next week.
    * Saturday and Sunday Temperature Ranges:
    Extreme Inland North Bay Valleys: 99 to 104 degrees. Inland
    North Bay: low to upper 90s. Inland East Bay: 95 to
    100 degrees. South/East SF Bay Shoreline: upper 80s to mid 90s.
    Big Sur & Santa Cruz Mountains: 95 to 105 degrees. Santa
    Clara Valley: 97 to 102 degrees. Southern Salinas Valley:100 to
    105 degrees. Pinnacles National Park area: 103 to 108 degrees.
    Downtown San Francisco/North Bay Shoreline: 70s to low 80s.
    Pacific Coast (including Ocean Beach): 60s to low 70s.
    * IMPACTS...Prolonged exposure to these temperatures, especially
    after an extended period of unseasonably cool temperatures,
    will increase the risk of heat related illnesses, particularly
    for vulnerable populations. Pets, crops, and livestock may
    also require extra care through the warm and dry weather.
    Individuals flocking to the coast for heat relief and
    unfamiliar with the state of the ocean may be at increased
    risk of hypothermia or being pulled out to sea by rip
    currents.
