High Surf Warning, High Surf Advisory, Coastal Flood Advisory

Statement as of 4:55 AM PST on January 20, 2017

Expires 9:00 AM EST on January 22, 2017


... High surf advisory remains in effect until 10 PM PST this
evening...
... High surf warning remains in effect from 10 PM this evening to
6 am PST Sunday...
... Coastal Flood Advisory remains in effect from 3 am Saturday to
6 am PST Sunday...

* coastal flooding... a combination of large wave runup and high
tide early Saturday morning will lead to an increased risk of
minor coastal flooding of low lying areas such as beach
parking lots and campgrounds.

* Surf... surf of 4 to 8 feet today will build to 10 to 16 feet by
late today through Saturday. The surf will slowly diminish
Sunday through Tuesday... but will remain above high surf
thresholds.

* Impacts... the large surf will likely cause additional beach
erosion and could potentially damage coastal structures... such
as piers. Strong rip currents that will create a risk of ocean
drowning. Sneaker waves can suddenly overrun previously dry
beaches and jetties. Minor coastal flooding of beach parking
lots... walkways and campgrounds is possible... especially
around the times of high tide.

Precautionary/preparedness actions...

A high surf warning means that large and battering surf could
damage coastal structures and will make swimming and rock jetties
very dangerous.

A high surf advisory means that high surf and rip currents will
make swimming and rock jetties dangerous.

Remember... swim near a lifeguard. If caught in a rip current
remain calm. Don't fight the current. Swim in a direction
following the shoreline. When out of the current... swim back to
shore. If tired... float or tread water until out of the rip
current. If unable to escape... face the shore and call or wave
for help.

A coastal Flood Advisory means that minor and shallow flooding is
occurring or imminent. Avoid low-lying coastal areas... especially
during high tides.







Wind Advisory

Statement as of 2:26 AM PST on January 20, 2017

Expires 9:00 AM EST on January 21, 2017


... Wind Advisory now in effect from 6 am this morning to 6 am PST
Saturday...

* winds and timing... areas of southeast to south winds 15 to 25
mph with gusts to 40 mph will develop early this morning... except
wind speeds will be 20 to 30 mph with gusts to 50 mph in the
Santa Monica Mountains. Winds will shift to west at similar
speeds this afternoon... then continue through late tonight
before diminishing.

* Impacts... gusty winds will make driving difficult... especially
for drivers of high profile vehicles. Since the soils are
wet... there is a heightened potential for downed trees.

Precautionary/preparedness actions...

When driving... use extra caution. Be prepared for sudden gusty
cross winds.





Special Statement

Statement as of 7:11 AM PST on January 20, 2017

Expires 10:00 PM EST on January 20, 2017


... Threat of strong thunderstorms with potential for locally
damaging wind gusts... heavy downpours... small hail... and isolated
waterspouts today across southwest California...

A strong upper level jet stream combined with increasing
instability will bring a chance of thunderstorms today across
southwest California... especially this afternoon. The greatest
threat of thunderstorms will be across Ventura and Los Angeles
counties as well as the adjacent coastal waters. Some of these
thunderstorms could be strong... with the main threats being
locally damaging winds that could down trees and power lines as
well as brief heavy downpours causing localized roadway flooding.
In addition... any thunderstorm that develops today will be capable
of producing small hail and dangerous cloud to ground
lightning... including beach areas.

Conditions are also favorable for isolated waterspouts across
the coastal waters... especially south of Ventura. Remember that
waterspouts do have the potential to come ashore as weak tornados
across coastal communities. The threat of strong thunderstorms
is expected to diminish by tonight.
