Wednesday. A Heat Advisory is in effect between 10 AM and 8 PM for
peak heat indices of 108F to 112F.
A return of near-normal shower and storm chances is anticipated
areawide today into Wednesday, with activity being driven by the sea

gusty winds of 45 to 55 mph, and heavy downpours that could lead to
minor, localized flooding. Activity will push offshore into the
evening hours.
Fog potential...Widespread fog is not forecast. Localized visibility
reductions due to smoke from new or existing fires will be possible
