.DISCUSSION...
Scattered showers and isolated thunderstorms are developing along
the sea breeze and this will continue through the afternoon. This
complicates the wind forecast as prevailing south to south-
southwesterly flow may abruptly shift to westerly or northerly as
outflow pushes away from collapsing storms. Cloudiness will also
vary considerably depending on the coverage of showers and storms.

Wind profile analysis/fire control over flat terrain is Favorable.

Fog potential for tonight is High.
