THE AMPLIFYING UPPER-TROUGH AND FRONT WILL CONTINUE TO LEAD TO
THUNDERSTORMS THROUGHOUT THE GREAT BASIN/FOUR CORNERS REGION AND
PORTIONS OF THE DESERT SOUTHWEST THROUGH THE NEXT COUPLE OF DAYS.
THE REMNANT MOISTURE FROM RACHEL WILL HELP CONTRIBUTE TO
EFFICIENT, LOCALLY HEAVY DOWNPOURS WITH A RISK FOR FLASH FLOODING.
A MODERATE RISK OF EXCESSIVE RAINFALL (LEVEL 3/4) REMAINS IN
EFFECT FOR PORTIONS OF SOUTHERN NEVADA, FAR SOUTHWESTERN UTAH, AND
FAR NORTHWESTERN ARIZONA WHERE SCATTERED TO WIDESPREAD FLASH
FLOODING IS POSSIBLE. A BROADER SLIGHT RISK IS IN PLACE THROUGHOUT
THE REGION FOR MORE SCATTERED INSTANCES OF FLASH FLOODING. THERE
IS A SLIGHT RISK FOR PORTIONS OF THE GREAT BASIN INTO THE DESERT
SOUTHWEST MONDAY FOR THE CONTINUED RISK OF SCATTERED FLASH
FLOODING. STORMS WILL START TO TAPER OFF BY TUESDAY AS CONDITIONS
BEGIN TO DRY OUT WITH A LINGERING ISOLATED FLASH FLOOD THREAT FOR
PORTIONS OF WESTERN AND NORTHERN UTAH. STORMS WILL COME TO AN END
INTO WEDNESDAY AS THE UPPER-ENERGY FINALLY SHIFTS EASTWARD TOWARDS
THE PLAINS.
THE NEXT STORM SUMMARY WILL BE ISSUED BY THE WEATHER PREDICTION
CENTER AT 800 PM PDT. PLEASE REFER TO YOUR LOCAL NATIONAL WEATHER
SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS EVENT.
