FIRE CONDITIONS IN THE WIND PRONE AREAS OF THE COLORADO RIVER  
VALLEY. WINDS WILL DIMINISH OVERNIGHT, AND LIGHTER WINDS WILL SET UP

..DISCUSSION FROM LAXFWFSGX
 
 
STRONG AND GUSTY EAST TO NORTHEAST WINDS OF 20 TO 35 MPH WITH GUSTS  
OF 50 TO 60 MPH AND LOCALLY UP TO 70 MPH WILL DEVELOP THIS MORNING  
AND CONTINUE IN SOME AREAS THROUGH FRIDAY MORNING. THE WIND,  
COMBINED WITH RELATIVE HUMIDITY IN THE SINGLE DIGITS, WILL CREATE  
CRITICAL FIRE WEATHER CONDITIONS THROUGH AND BELOW PASSES AND  
CANYONS, AND ALONG THE COASTAL MOUNTAIN SLOPES AND FOOTHILLS.  
HUMIDITY RECOVERY WILL BE VERY POOR WHERE WINDS STAY UP OVERNIGHT.  
WINDS WILL RELAX ON FRIDAY, BUT CRITICALLY LOW RELATIVE HUMIDITY  
WILL CONTINUE. A BRIEF PERIOD OF ONSHORE WINDS AND HIGHER HUMIDITY  
WILL OCCUR LATE FRIDAY THROUGH SATURDAY AFTERNOON BEFORE WINDS TURN  
BACK OFFSHORE SUNDAY INTO EARLY MONDAY, WITH ANOTHER PERIOD OF  
CRITICAL FIRE WEATHER CONDITIONS POSSIBLE.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
POTENT, BUT DRY, WEATHER SYSTEM WILL BRUSH THROUGH THE REGION TODAY  
GENERATING STRONG GUSTY NORTH WINDS FOR SOUTHEAST CA AND THE LOWER  
CO RIVER VALLEY. RED FLAG CONDITIONS ARE FORECAST ALONG AND WEST OF  
THE CO RIVER. BREEZY CONDITIONS WILL ALSO BE OBSERVED ACROSS  
SOUTH-CENTRAL AZ, ESPECIALLY FOR AREA RIDGETOPS AND GAPS. DAYTIME  
HUMIDITIES WILL FALL 9-15 PERCENT FOR THE LOWER ELEVATIONS AND NEAR  
20 PERCENT FOR THE EASTERN AZ HIGHER TERRAIN. WINDS WILL BEGIN TO  
RELAX INTO THE EVENING HOWEVER REMAIN BREEZY OVER AREA RIDGETOPS  
OVERNIGHT.
