...Slight chance of thunderstorms across most coastal waters
tonight and Saturday...

A cold upper level low pressure system will move across the
coastal waters later tonight and Saturday bringing unstable air
and moisture to the region. Scattered showers will develop late
this evening and become more widespread by daybreak on Saturday
morning, especially from Point Conception southward to Orange
County. There will be isolated thunderstorms over the waters when
the coldest part of this system moves by generating the potential
for brief heavy downpours, small hail, gusty winds and choppy
seas. In addition, dangerous waterspouts could develop with any
thunderstorm activity over the water.

The threat of thunderstorms will slowly decrease late Saturday
afternoon as the low pressure system passes to the east.
