...FIRE WEATHER WATCH CANCELLED BOTH TODAY AND TUESDAY FOR SOUTHEAST 
CALIFORNIA INCLUDING JOSHUA TREE NATIONAL PARK...IMPERIAL AND 
EASTERN RIVERSIDE COUNTIES...AND THE LOWER COLORADO RIVER VALLEY DUE

DISCUSSION...A STRONG UPPER LOW PRESSURE SYSTEM WILL PUSH ACROSS THE 
REGION THROUGH TUESDAY. THIS SYSTEM WILL BE CREATING GUSTY WINDS 
OVER SOUTHEAST CALIFORNIA AND THE LOWER COLORADO RIVER VALLEY OF 
SOUTHWEST ARIZONA BOTH THIS AFTERNOON AND TUESDAY. HOWEVER...A BIT 
OF AN INCREASE IN LOW LEVEL MOISTURE TODAY WILL KEEP MOST HUMIDITIES 
ABOVE RED FLAG CRITERIA...AS WILL COOLER TEMPERATURES ON TUESDAY. 
LOWEST HUMIDITIES TODAY WILL PROBABLY DROP INTO THE 15 TO 20 PERCENT 
RANGE. THEREFORE...THE FIRE WEATHER WATCH HAS BEEN CANCELLED FOR 
BOTH TODAY AND TUESDAY FOR CALIFORNIA FIRE WEATHER ZONES 230...231 
...AND 232...AND FOR ARIZONA FIRE WEATHER ZONES 131. 

PLEASE ADVISE THE APPROPRIATE OFFICIALS OR FIRE CREWS IN THE FIELD
