...INCREASED THREAT OF LANDSLIDES AND DEBRIS FLOWS ACROSS THE
MOUNTAINS AND FOOTHILLS THIS WEEKEND...
AFTER HURRICANE ISAIAS MAKES LANDFALL OVER THE WESTERN FLORIDA
PANHANDLE FRIDAY EVENING, THE CENTER OF THE REMNANT CIRCULATION
IS EXPECTED TO TAKE A NORTHWARD TRACK TO THE WEST OF THE MOUNTAINS
SATURDAY AFTERNOON AND SATURDAY NIGHT. ON THIS TRACK, SIGNIFICANT
TROPICAL MOISTURE WILL BE FORCED UPSLOPE BY A STRONG SOUTHEAST
FLOW, RESULTING IN HEAVY RAIN PARTICULARLY NEAR THE BLUE RIDGE
ESCARPMENT AND THE SOUTHEAST FACING SLOPES OF THE BALSAM AND BLACK
MOUNTAINS.
RAIN IS EXPECTED TO DEVELOP ACROSS THE WESTERN CAROLINAS AND
NORTHEAST GEORGIA EARLY SATURDAY MORNING AND WILL INCREASE IN
INTENSITY ALONG AND NEAR THE ESCARPMENT SATURDAY AFTERNOON.
PERIODS OF HEAVY RAIN ARE LIKELY, ESPECIALLY LATE SATURDAY
AFTERNOON THROUGH THE EARLY MORNING HOURS SUNDAY. THE HEAVY RAIN
MAY RESULT IN SIGNIFICANT FLOODING ALONG CREEKS AND STREAMS. BY
SUNDAY MORNING, RAINFALL AMOUNTS OF FIVE TO TEN INCHES ARE
POSSIBLE ALONG AND NEAR THE BLUE RIDGE ESCARPMENT AND THE
SOUTHEAST FACING SLOPES OF THE MOUNTAINS. RAINFALL OF FIVE INCHES
OR MORE IN SIMILAR STORMS HAS BEEN ASSOCIATED WITH AN INCREASED
RISK OF LANDSLIDES AND ROCKSLIDES.
LANDSLIDES, INCLUDING FAST-MOVING DEBRIS FLOWS CONSISTING OF
WATER, MUD, FALLING ROCKS, TREES, AND OTHER LARGE DEBRIS,
ARE MOST LIKELY WITHIN SMALL VALLEYS THAT DRAIN STEEP SLOPES.
LANDSLIDES ARE POWERFUL AND POTENTIALLY DEADLY, CAPABLE OF
WASHING OUT ROADS, BRIDGES, AND HOMES. PEOPLE LIVING IN AREAS
PRONE TO LANDSLIDES SHOULD BE AWARE OF THE DANGER AND BE PREPARED
TO ACT.
HERE ARE RECOMMENDED ACTIONS TO CONSIDER BOTH AHEAD OF THE STORM
AND WHEN THE HEAVY RAIN BEGINS.
BEFORE THE STORM:
1. KNOW YOUR RISK. USE THE NCGS LANDSLIDE HAZARDS WEBSITE
LANDSLIDESNCGS.ORG RESOURCES TO CHECK WHETHER YOUR HOME OR
COMMUNITY IS IN A LANDSLIDE-PRONE AREA. IF IT IS, MAKE PLANS TO
STAY ELSEWHERE BEFORE THE STORM ARRIVES.
2. HAVE A PLAN TO LEAVE EARLY. IF YOU LIVE ON A MOUNTAINSIDE OR
IN A COVE AT THE BASE OF A MOUNTAIN, ESPECIALLY NEAR A STREAM, BE
READY TO EVACUATE. FOLLOW EVACUATION ORDERS GIVEN BY LOCAL
OFFICIALS. GO TO A STURDY SHELTER ON HIGHER GROUND SUCH AS A
WELL-BUILT HOME, CHURCH OR SCHOOL LOCATED AWAY FROM CREEKS AND
STREAMS.
3. MANY LANDSLIDE FATALITIES OCCUR WHEN PEOPLE ARE ASLEEP. IF YOU
ARE UNABLE TO OR CHOOSE NOT TO EVACUATE, IDENTIFY A ROOM ON THE
TOP FLOOR OR DOWNHILL SIDE OF YOUR HOME WHERE YOU CAN SHELTER IN
PLACE DURING THE STORM.
DURING THE STORM:
1. UNLESS YOU NEED TO EVACUATE, STAY OFF MOUNTAIN ROADS. AVOID
DRIVING NEAR STEEP SLOPES OR ACROSS STREAM VALLEYS, PARTICULARLY
AT NIGHT. NEVER ATTEMPT TO DRIVE ACROSS A FLOODED ROAD. HAZARDS
INCLUDE WASHED-OUT ROADS, UNSTABLE BRIDGES, AND FALLING OR
FLOWING DEBRIS. TURN AROUND, DON'T DROWN!
2. MOVE TO SAFER GROUND. IF YOU ARE NEAR STEEP SLOPES OR SMALL
STREAMS IN VALLEYS, RELOCATE TO A STURDY SHELTER AWAY FROM CREEKS
AND DRAINAGES BEFORE HEAVY RAIN ARRIVES.
3. STAY ALERT TO SIGNS OF DANGER. BE ESPECIALLY CAUTIOUS DURING
INTENSE BURSTS OF RAINFALL. IF YOU HEAR TREES SNAPPING, BOULDERS
KNOCKING, OR LOUD CRASHES, A LANDSLIDE MIGHT BE ONGOING OR
IMMINENT. STAY INDOORS AND DO NOT GO OUTSIDE TO INVESTIGATE AS YOU
COULD BE SWEPT AWAY.
4. MOVE TO A HIGHER SPOT INSIDE YOUR HOME SUCH AS GOING UPSTAIRS
OR GETTING ON TOP OF KITCHEN COUNTERS TO AVOID BEIND SWEPT AWAY. A
SMALL INTERIOR ROOM WITH LIMITED FURNISHINGS, SUCH AS A CLOSET OR
BATHROOM, ON THE TOP FLOOR OR DOWNHILL SIDE OF YOUR HOME MAY OFFER
THE BEST PROTECTION.
5. STAY INFORMED. KEEP TUNED TO NOAA WEATHER RADIO OR LOCAL MEDIA
FOR THE LATEST WARNINGS AND UPDATES. REMEMBER THAT EMERGENCY
RESPONDERS MAY BE DELAYED OR UNABLE TO REACH LANDSLIDE AREAS, SO
BE PREPARED TO ACT QUICKLY TO PROTECT YOURSELF.
