URGENT - WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
824 PM PDT Fri Oct 20 2017

...Gusty winds to impact portion of the region tonight into
Saturday...

...Excessive Heat Watch in effect for Los Angeles and Ventura
County coast and valleys and the Santa Barbara County south coast
Monday and Tuesday...

.Expect gusty west to northwest winds this evening, then winds
will turn northerly tonight as high pressure builds to the north
of the state. On Saturday winds will become more offshore and a
traditional Santa Ana pattern develops over eastern Ventura and
western Los Angeles Counties this weekend.

Early next week, strong high pressure and a weak to moderate
Santa Ana wind event will produce record setting hot temperatures
across southwest California. The hottest days are expected to be
Monday and Tuesday where highs near or in excess of 100 degrees
are expected across much of the coast and valley region of Los
Angeles and Ventura counties, including the Santa Monica
Mountains, as well as the south coast of Santa Barbara County.
Overnight temperatures will also be quite warm, especially in the
foothills and Santa Monica Mountains where temperatures will only
drop to the mid to upper 70s and possibly lower 80s.
