161 FNUS85 KVEF 040850 FWLVEF ECCDA DISCUSSIONS NATIONAL WEATHER SERVICE LAS VEGAS NV 150 AM PDT THU JUL 4 2024 ##################################################################### ## ## ## DISCUSSIONS FROM THE LATEST FWF BELOW ## ## ## ##################################################################### ...DISCUSSION FROM RNOFWFVEF... A RARE AND DANGEROUS LONG DURATION HEATWAVE WILL PERSIST AT LEAST THROUGH THE MIDDLE OF NEXT WEEK AS A STRONG RIDGE OF HIGH PRESSURE SITS OVER THE REGION. NUMEROUS LONG STANDING HEAT RECORDS ARE LIKELY TO BE CHALLENGED OR BROKEN, AND FUEL MOISTURE WILL CONTINUE TO DECREASE. DRY CONDITIONS WILL PREVAIL THROUGH THE PERIOD WITH NO SIGNS OF MONSOON MOISTURE UNTIL WEDNESDAY AT THE EARLIEST. ...DISCUSSION FROM LAXFWFSGX... THE LONG-DURATION PERIOD OF HOT AND DRY WEATHER ACROSS SOUTHERN CALIFORNIA WILL AID IN A PERSISTENT DOWNWARD TREND IN BOTH DEAD AND LIVE FUEL MOISTURE. THE LOW HUMIDITY COMBINED WITH GUSTY SEA BREEZE WINDS WILL BRING ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS EACH AFTERNOON AND EVENING. THE MARINE LAYER WILL KEEP AREAS NEAR THE COAST COOLER WITH HIGHER HUMIDITY. AS EVIDENCED BY THE RECENT KITCHEN, MCCAIN, AND NUMEROUS OTHER FIRES, LOCAL GRASS FUELS ARE CURED AND VERY AVAILABLE TO BURN. THE PRIMARY FACTORS LIMITING ANY MORE CRITICAL FIRE WEATHER POTENTIAL ARE A LACK OF STRONG WINDS (OUTSIDE OF THE TYPICAL DIURNALLY-DRIVEN WINDS) ANY GIVEN DAY, AS WELL AS LIVE FUEL MOISTURE. LIVE FUEL MOISTURE WILL, HOWEVER, BE STEADILY DROPPING/DRYING OUT AS WE HEAD THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK. THIS WILL INCREASE THE ABILITY OF LARGER FUELS LIKE BRUSH, CHAPARRAL, AND TREES TO BURN. ENERGY RELEASE COMPONENTS ARE STEADILY TRENDING UPWARD TOWARD THE 40TH PERCENTILE AND EXPECTED TO APPROACH THE 45TH-50TH PERCENTILE NEXT WEEK. ...DISCUSSION FROM PHXFWFPSR... HOT AND DRY CONDITIONS WILL PREVAIL ACROSS THE AREA THROUGH AT LEAST THE WEEKEND AS STRONG HIGH PRESSURE SETTLES IN FROM THE NORTHWEST. EXCESSIVELY HOT TEMPERATURES WITH HIGHS GENERALLY BETWEEN 112-117 DEGREES ARE EXPECTED ACROSS THE LOWER DESERTS EACH DAY THROUGH EARLY NEXT WEEK. DAILY MINRH VALUES THROUGH THE WEEKEND WILL FALL BETWEEN 5-15% ACROSS THE LOWER DESERTS, WHILE HIGHER TERRAIN AREAS IN ARIZONA WILL MOSTLY SEE 10-20%. WINDS WILL FOLLOW DIURNAL TRENDS, OCCASIONALLY GUSTING TO 20 MPH DURING THE AFTERNOON HOURS. THE COMBINATION OF THE VERY HOT AND DRY CONDITIONS WILL LEAD TO AN INCREASED FIRE DANGER THREAT. ##################################################################### ## ## ## AFTER REVIEWING THE FWF DISCUSSIONS (ABOVE) - COMPLETE ## ## THE DISCUSSION (BELOW) FOR THE ECCDA FORECAST ## ## WHEN DONE CLICK TRANSMIT, PRODUCT SENT AS KVEFFWLVEF ## ## ## ##################################################################### ECC027-050300- SAN BERNARDINO ECC DISPATCH- DISCUSSION FOR SAN BERNARDINO ECC DISPATCH 150 AM PDT THU JUL 4 2024 A RARE AND DANGEROUS LONG DURATION HEATWAVE WILL PERSIST AT LEAST THROUGH THE MIDDLE OF NEXT WEEK AS A STRONG RIDGE OF HIGH PRESSURE SITS OVER THE REGION.
