 High Surf Advisory
Statement as of 1:27 am PDT on May 22, 2008
|
... High surf advisory now in effect until 1 am PDT Friday...
The high surf advisory is now in effect until 1 am PDT Friday.
Surf of 4 to 7 feet is expected with sets to 8 feet. The northwest
wind swell will decrease tonight and the surf will be below high
surf criteria by Friday morning. High tides will be 5.8 feet
tonight and should not cause any problems... although coastal areas
may experience some beach erosion.
Fishing or observing large waves from exposed coastal structures
or rocks during high surf conditions can be dangerous. Large
waves can break across previously dry areas. Swimming or surfing
in these waves is dangerous due to the powerful waves and very
strong rip currents.
A high surf advisory means that high surf will affect beaches in
the advisory area... producing strong rip currents and localized
beach erosion.

 Special Weather Statement
Statement as of 9:15 am PDT on May 22, 2008
|
... Cool and unsettled weather through Memorial Day weekend...
A developing low pressure system will bring cool and unsettled
weather with a chance of showers and thunderstorms today through
Sunday. The best chance for showers and thunderstorms will be over
the mountains. People with outdoor activities should expect periods
of showers or thunderstorms during the Holiday weekend.
Thunderstorms contain deadly lightning and may produce brief heavy
rain... gusty winds... and small hail. Snow is possible above 7000
feet in the san gorgonio wilderness and on mount San Jacinto.
Rainfall amounts will be highly variable due to the showery nature
of the precipitation.
The weather will be considerably cooler than last week with high
temperatures running 10 to 20 degrees below seasonal averages.
Interested parties should stay informed on the latest forecast.
