OF THE TIMBER AND PLASKETT BURN SCARS, BRINGING GUSTY, ERRATIC
WINDS AND MODERATE TO HEAVY RAIN. DRIER CONDITIONS RETURN FRIDAY
INTO THE WEEKEND AS THE LOW PRESSURE SYSTEM SHIFTS INLAND INTO
CENTRAL AND SOUTHERN CALIFORNIA.
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
