...FLASH FLOOD WATCH IN EFFECT THROUGH LATE TONIGHT...

THE NATIONAL WEATHER SERVICE IN DENVER HAS ISSUED A

* FLASH FLOOD WATCH FOR THE NORTHEAST PLAINS AND FRONT RANGE
FOOTHILLS IN COLORADO INCLUDING THE DENVER METRO AREA

* THROUGH LATE TONIGHT.

* NUMEROUS THUNDERSTORMS WILL DEVELOP BY THIS EVENING AND SHIFT
SLOWLY EASTWARD OVERNIGHT. THE AIR IS VERY MOIST AND SOME OF THE
STORMS COULD BE STATIONARY FOR A FEW HOURS RESULTING IN SEVERAL
INCHES OF RAIN AND FLASH FLOODING. THE RISK OF STATIONARY STORMS
AND FLASH FLOODING IS HIGHEST SOUTH OF A LINE FROM CASTLE ROCK
TO AKRON...BUT THERE IS STILL A LOWER THREAT OF FLOODING FROM
SLOW MOVING STORMS ACROSS DENVER AND IN AREAS FURTHER NORTH.
RAINFALL OF 2 INCHES IN AN HOUR IS LIKELY IN SOME OF THE
STORMS...AND UP TO 4 INCHES IN 2 TO 3 HOURS IS POSSIBLE IF A
STORM BECOMES STATIONARY.

* FLASH FLOODING MAY CAUSE RAPID RISES IN RIVERS AND STREAMS...
AND FLOODING IN NORMALLY DRY CREEKS AND LOW LYING AREAS. HEAVY
RAIN MAY OVERWHELM DRAINAGE SYSTEMS CAUSING OVERTOPPING OF ROADS
AT CREEK CROSSINGS AND FLOODING OF CITY STREETS. RURAL ROADS MAY
WASH OUT...AND ROCK AND MUD SLIDES ARE POSSIBLE IN MOUNTAIN
AREAS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD
TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION
SHOULD FLASH FLOOD WARNINGS BE ISSUED.
