A MARINE LAYER NEAR 2500 FEET DEEP WILL PERSIST INTO THIS MORNING.

ALONG AND BELOW THE COASTAL SLOPES OF THE MOUNTAINS FOR TONIGHT 

INTO WEDNESDAY WITH THE STRONGER GUSTS TO 35 TO 45 MPH. LOWEST 

DAYTIME HUMIDITY FOR THE VALLEYS, INLAND ORANGE COUNTY, AND THE 

LOWER COASTAL SLOPES OF THE MOUNTAINS FOR TUESDAY AND WEDNESDAY
