THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN UTAH AND WESTERN
COLORADO.

.DAY ONE...TODAY AND TONIGHT

ISOLATED SHOWERS AND THUNDERSTORMS WILL EXPAND THIS MORNING OVER
SOUTHEAST UTAH AND WESTERN COLORADO...BECOMING SCATTERED IN THE
WESTERN COLORADO HIGH COUNTRY. WETTING RAINS ARE EXPECTED FOR
MOST MOUNTAIN LOCATIONS. IN THE VALLEYS...BRIEF HEAVY SHOWERS
WILL ACCOMPANY THE STRONGEST THUNDERSTORMS WITH LOCALIZED GUSTS OF
30 TO 40 MPH. FREQUENT AND DEADLY CLOUD TO GROUND LIGHTNING
STRIKES WILL ACCOMPANY THUNDERSTORMS.

LOCALIZED MUD DEBRIS FLOWS OR FALLING ROCKS WILL BE POSSIBLE IN
THOSE AREAS PRONE TO SUCH ACTIVITY...LIKE STEEP TERRAIN. MOST
STORM ACTIVITY WILL DIE DOWN BY MIDNIGHT...BUT ISOLATED STORMS
WILL LINGER THROUGH THE OVERNIGHT HOURS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

EXPECT SHOWER AND THUNDERSTORM ACTIVITY TO INCREASE ON TUESDAY WITH
THE POTENTIAL FOR HEAVY RAIN AS A DISTURBANCE OF TROPICAL ORIGIN
SWEEPS OVER THE FORECAST AREA. THE STRONGER STORMS COULD GENERATE
EXCESSIVE RAINFALL AMOUNTS WITH THE POSSIBILITY OF FLASH FLOODS
AND MUD/DEBRIS FLOWS.

OTHERWISE...EXPECT SCATTERED AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS THROUGH THE WEEKEND WITH A CONTINUED THREAT OF
LOCALIZED HEAVY RAIN. COVERAGE IS EXPECTED TO DECREASE BY SATURDAY
AND SUNDAY.


.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT EXPECTED TODAY OR TONIGHT...HOWEVER
SPOTTERS ARE ENCOURAGED TO RELAY RAINFALL AMOUNTS OR ANY OBSERVED
FLOODING TO THE GRAND JUNCTION FORECAST OFFICE.
