PATTERN OF THE LAST FIVE DAYS AND A NEW REGIME OF WARMER AIR AND
SLIGHTLY LESS BLUSTERY CONDITIONS. THE WINDS ARE EXPECTED TO RETURN
LATE THIS EVENING IN THE MOUNTAINS AND SOMETIME OVERNIGHT TO MANY OF
THE VALLEYS OF LOS ANGELES AND VENTURA COUNTIES. THEREFORE...NEW

WINDS WILL PREVENT THE SAME FROM HAPPENING IN AREAS UNDER A WIND
ADVISORY. PLEASE CONSULT THE PRODUCT LAXNPWLOX FOR AREAS WITH NEAR

ABOVE SEASONAL NORMALS FOR THURSDAY AND FRIDAY. THE SKIES WILL BE
CLEAR AND OFFSHORE FLOW WILL BE STRONG ENOUGH TO CREATE ADVISORY
LEVEL WINDS RIGHT ON THROUGH THURSDAY MORNING. THE OFFSHORE WINDS

.LONG TERM (SAT-TUE)...
THE MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT IN KEEPING THE WARM
RIDGE OF HIGH PRESSURE OVER SOUTHWEST CALIFORNIA THROUGHOUT THE
