...HIGH AND FAST RIVERS AGAIN THIS WEEKEND...

HIGH RIVER LEVELS IN NORTHEASTERN COLORADO WILL BE THE RULE
THROUGHOUT THE COMING WEEKEND. THERE WILL BE LITTLE OR NO ADDITION
OF WATER TO THE RIVERS DUE TO SNOWMELT...BUT LOCALLY HEAVY RAINS ARE
FORECAST OVER THE AREA THROUGH SUNDAY AND THESE MAY PRODUCE FLASH
FLOODING ON SMALLER STREAMS. PERSONS ON OR NEAR RIVERS AND STREAMS
IN NORTHEASTERN COLORADO THIS WEEKEND SHOULD BE ALERT FOR RAPID
RISES IN RIVER LEVELS.

RESERVOIR RELEASES CONTINUE TO ACCOUNT FOR MUCH OF THE HIGH WATER
DOWNSTREAM OF DAMS THROUGHOUT THE AREA. THESE RELEASES ARE BEING
CLOSELY MONITORED AND ANY FLOODING RESULTING FROM THEM SHOULD BE
MINOR UNLESS SIGNIFICANT RAIN FALLS IN THE VICINITY.

TO REPEAT...THE NEXT FEW DAYS WILL SEE THE HIGHEST RIVER LEVELS OF
THE SEASON ON MOST STREAMS IN NORTHEASTERN COLORADO AND ANYONE ON OR
NEAR THEM SHOULD EXERCISE CAUTION. IN ADDITION...MUD AND ROCK SLIDES
MAY BE A CONCERN IN SOME BACK COUNTRY AREAS.

...HEAVY RAINS MOVING INTO THE FOOTHILLS...

THUNDERSTORMS WITH HEAVY RAINS ARE MOVING INTO THE FOOTHILLS OF
LARIMER...BOULDER...JEFFERSON...DOUGLAS...CLEAR CREEK...GILPIN AND
PARK COUNTIES.

RADAR AND PRECIPITATION GAUGES SHOW THAT UPWARDS OF AN INCH OF RAIN
HAS FALLEN FROM SOME OF THESE STORMS OVER THE DENVER METRO AREA AND
SOME OF THE HIGHER FOOTHILLS LOCATIONS.  WITH RIVERS ALREADY RUNNING
HIGH FROM SNOWMELT...THESE HEAVY RAINS COULD CAUSE SOME OF THE
RIVERS TO RISE RAPIDLY LATER TODAY AND TONIGHT WHICH COULD LEADING
TO MORE SIGNIFICANT FLOODING.

PERSONS LIVING OR TRAVELING NEAR STREAMS ALONG THE FRONT RANGE OF
NORTHEAST COLORADO SHOULD BE ON THE LOOKOUT FOR RAPIDLY RISING RIVER
LEVELS THIS AFTERNOON AND TONIGHT AND BE PREPARED TO TAKE QUICK
ACTION SHOULD MORE SIGNIFICANT FLOODING OCCUR.
