SPECIAL WEATHER STATEMENT

1216 PM MDT SUN JUN 08 1997

...SOUTH CENTRAL AND SOUTHEAST COLORADO RIVERS CONTINUE TO RUN
HIGH...

MANY RIVERS IN SOUTH-CENTRAL AND SOUTHEASTERN COLORADO CONTINUE
TO RUN HIGH DUE TO RECENT SHOWER AND THUNDERSTORM ACTIVITY AS
WELL AS MILD TEMPERATURES OVER THE HIGHER ELEVATIONS.

SOME RIVERS...CREEKS AND ARROYOS THAT ARE RUNNING HIGH ARE THE:

ARKANSAS RIVER NEAR THE COMMUNITIES OF
AVONDALE...LA JUNTA...LAS ANIMAS...NATHROP AND ABOVE CANON CITY

CONEJOS RIVER NEAR MOGOTE

FOUNTAIN CREEK NEAR FOUNTAIN

MONUMENT CREEK NEAR COLORADO SPRINGS

CROOKED ARROYO NEAR LA JUNTA

COTTONWOOD CREEK NEAR BUENA VISTA

CHALK CREEK NEAR NATHROP

BEAVER CREEK ABOVE HIGHWAY 115 IN NORTHEAST FREMONT COUNTY

DAYTIME TEMPERATURES OVER THE HIGHER ELEVATIONS ARE EXPECTED TO
REMAIN RELATIVELY WARM THROUGH THE WEEKEND.  STEADY RIVER RISES
ARE EXPECT TO CONTINUE WITH SEVERAL RIVERS REACHING BANKFULL
STAGES.  SOME RIVERS COULD EXCEED BANKFULL LEVELS DUE TO THE
CONTINUED SNOWMELT IN COMBINATION WITH SHOWER AND THUNDERSTORM
ACTIVITY.

COMPUTER MODELS INDICATE THAT A UPPER LEVEL STORM SYSTEM WILL
CONTINUE TO INFLUENCE THE REGION WITH SHOWER AND THUNDERSTORM
ACTIVITY...HEAVY AT TIMES THROUGH AT LEAST EARLY MONDAY WHICH
MAY CONTRIBUTE TO RIVER RISES.

THESE RIVERS ARE CURRENTLY FLOWING FAST AND YOU ARE STRONGLY
URGED TO STAY AWAY FROM THE BANKS.  FAST MOVING WATER CAN ERODE
BANKS QUICKLY...POSING A THREAT TO ANYONE STANDING NEARBY. WATER
ENTHUSIASTS SHOULD BE VERY CAREFUL ON AND NEAR RIVERS THIS TIME
OF YEAR.

WITHIN BANK RISES AND MINOR FLOODING ARE TYPICAL DURING THE
SNOWMELT RUNOFF SEASON IN COLORADO.  HOWEVER...HEAVY RAIN ON TOP
OF SNOWMELT CAN QUICKLY LEAD TO MAJOR FLOODING.  THE NATIONAL
WEATHER SERVICE ADVISES YOU TO STAY INFORMED OF THE LATEST
WEATHER FORECASTS AND WARNINGS AND STAY ALERT TO THE WEATHER
AROUND YOU.4

KEEP CHILDREN AND OTHERS AWAY FROM FAST FLOWING WATER AND STORM
DRAINS...WHICH COULD BECOME DEADLY DURING FLOODING EVENTS.

A FLASH FLOOD WARNING MEANS THAT FLOODING IS OCCURRING OR IS

A VEHICLE OR ON FOOT...DO NOT ATTEMPT TO CROSS BRIDGES...DIPS
...OR LOW SPOTS IF WATER COVERS YOUR PATH.  NEVER TRY TO CROSS
SWIFTLY FLOWING WATER ON FOOT...BECAUSE YOU COULD BE SWEPT AWAY
IN A MATTER OF SECONDS BY THE POWERFUL FORCE OF THE RUSHING
WATER.

A FLASH FLOOD WARNING MEANS THAT FLOODING IS OCCURRING OR
IMMINENT.  AT NIGHT IT IS DIFFICULT TO SEE FLOOD SITUATIONS
DEVELOPING.  THE FLOODING RAIN MAY BE MANY MILES AWAY FROM

A FLASH FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR
OCCURRING.  BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARD TO

BRIDGE MAY BE WASHED OUT AND THE FAST FLOWING WATER COULD BE
SEVERAL FEET DEEP.  DRIVING INTO THIS SITUATION COULD BE FATAL.
DO NOT STAY IN LOW AREAS WHICH CAN FLOOD QUICKLY WHEN WATER IS ON

THE FOLLOWING IS A LIST OF SEVERE THUNDERSTORM SAFETY RULES THAT
CAN BE PASSED ALONG TO ALL SOUTHERN COLORADANS.

SEVERE THUNDERSTORMS CAN BRING DAMAGING WINDS WELL OVER 60 MPH.
GO TO A STRONG BUILDING AND GET TO THE LOWEST LEVEL AWAY FROM
WINDOWS.  LIGHTNING IS A DANGER WITH EVERY THUNDERSTORM...SO TRY
TO GET INDOORS.  IF CAUGHT OUTSIDE...GET IN A VEHICLE...DO NOT
TOUCH METAL OBJECTS...AND AVOID WATER.

IN THUNDERSTORMS WITH LITTLE RAIN...GUSTY WINDS OVER 60 MPH ARE
POSSIBLE.  DO NOT BE TEMPTED TO STAY OUTDOORS...AS DEADLY
LIGHTNING CAN STRIKE IN NEARBY AREAS WHERE IT IS NOT RAINING.  GO
TO A STRONG BUILDING AND STAY AWAY FROM WINDOWS...ELECTRICAL
APPLIANCES...AND TELEPHONES...UNTIL THE STORM HAS PASSED INTO THE
DISTANCE.
SEVERE THUNDERSTORMS OVER WATER...ESPECIALLY RESERVOIRS...CAN BE
VERY DANGEROUS...PRODUCING DEADLY LIGHTNING...3/4 INCH OR LARGER
DESTRUCTIVE HAIL...AND WINDS GREATER THAN 58 MPH...WHICH CAN
CAPSIZE AND SINK BOATS.  BOATERS AND THOSE WHO ARE FISHING MUST
GO TO SHORE AND FIND SHELTER ON LAND BEFORE SEVERE STORMS ARRIVE.

TORNADO-LIKE FEATURES ARE COMMON IN SOUTHERN COLORADO.
STRONGLY HEATED AIR MOVES UPWARD RAPIDLY AND IS REPLACED BY
SWIRLING WINDS...CREATING DUST DEVILS. COLD AIR FUNNELS ARE
FAIRLY WEAK ROTATIONS...THAT CAN TOUCH GROUND BRIEFLY.  BOTH CAN
BRING MINOR DAMAGE IN A SMALL AREA...AND ARE RARELY LIFE
THREATENING.

IF YOU SEE SEVERE WEATHER...WHICH IS 3/4 INCH OR LARGER DIAMETER
HAIL...DAMAGING WINDS GREATER THAN 58 MPH OR A TORNADO...CONTACT
YOUR LOCAL LAW ENFORCEMENT AGENCY AND ASK THEM TO RELAY YOUR
INFORMATION TO THE NATIONAL WEATHER SERVICE IN PUEBLO.
