SITUATION OVERVIEW
------------------
HURRICANE HELENE IS EXPECTED TO MAKE LANDFALL OVER THE FLORIDA
PANHANDLE THURSDAY EVENING AND RACE NORTH ACROSS GEORGIA. SIGNIFICANT
FLASH FLOODING AND MAINSTEM RIVER FLOODING IS EXPECTED THURSDAY INTO
EARLY FRIDAY, ESPECIALLY ALONG THE BLUE RIDGE ESCARPMENT. WIND GUSTS
OF 40 TO 50 MPH WILL BE ASSOCIATED WITH HELENE AS THE STORM TRACKS
JUST WEST OF THE COUNTY WARNING AREA THURSDAY NIGHT INTO FRIDAY
MORNING. THE COMBINATION OF SATURATED SOILS AND STRONG WIND GUSTS WILL
RESULT IN WIDESPREAD TREES DOWN, LEADING TO NUMEROUS POWER OUTAGES.
NUMEROUS LANDSLIDES MAY OCCUR ACROSS THE MOUNTAINS, WITH A COUPLE OF
LARGE, DAMAGING DEBRIS FLOWS OR SLOPE FAILURES. ISOLATED TORNADOES
WILL BE POSSIBLE DURING THIS EVENT AS WELL.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
DEVASTATING IMPACTS ACROSS THE NORTH CAROLINA MOUNTAINS, NORTHEAST
GEORGIA, AND UPSTATE SOUTH CAROLINA. POTENTIAL IMPACTS INCLUDE:
- EXTREME RAINFALL FLOODING MAY PROMPT NUMEROUS EVACUATIONS AND
RESCUES.
- RIVERS AND TRIBUTARIES MAY OVERWHELMINGLY OVERFLOW THEIR BANKS
IN MANY PLACES WITH DEEP MOVING WATER. SMALL STREAMS, CREEKS,
CANALS, ARROYOS, AND DITCHES MAY BECOME RAGING RIVERS. IN
MOUNTAIN AREAS, DEADLY RUNOFF MAY RAGE DOWN VALLEYS WHILE
INCREASING SUSCEPTIBILITY TO ROCKSLIDES AND MUDSLIDES. FLOOD
CONTROL SYSTEMS AND BARRIERS MAY BECOME STRESSED.
- FLOOD WATERS CAN ENTER NUMEROUS STRUCTURES WITHIN MULTIPLE
COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. NUMEROUS PLACES WHERE FLOOD WATERS MAY COVER ESCAPE
ROUTES. STREETS AND PARKING LOTS BECOME RIVERS OF RAGING WATER
WITH UNDERPASSES SUBMERGED. DRIVING CONDITIONS BECOME VERY
DANGEROUS. NUMEROUS ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED
OR WASHED OUT.
* WIND:
PROTECT AGAINST HAZARDOUS WIND HAVING POSSIBLE LIMITED IMPACTS ACROSS
MOST OF THE WESTERN CAROLINAS AND NORTHEAST GEORGIA. POTENTIAL
IMPACTS INCLUDE:
- DAMAGE TO PORCHES, AWNINGS, CARPORTS, SHEDS, AND UNANCHORED
MOBILE HOMES. UNSECURED LIGHTWEIGHT OBJECTS BLOWN ABOUT.
- MANY LARGE TREE LIMBS BROKEN OFF. A FEW TREES SNAPPED OR
UPROOTED, BUT WITH GREATER NUMBERS IN PLACES WHERE TREES ARE
SHALLOW ROOTED. SOME FENCES AND ROADWAY SIGNS BLOWN OVER.
- A FEW ROADS IMPASSABLE FROM DEBRIS, PARTICULARLY WITHIN URBAN
OR HEAVILY WOODED PLACES. HAZARDOUS DRIVING CONDITIONS ON
BRIDGES AND OTHER ELEVATED ROADWAYS.
- SCATTERED POWER AND COMMUNICATIONS OUTAGES.
* TORNADOES:
PROTECT AGAINST A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS
ACROSS THE WESTERN CAROLINAS AND NE GEORGIA. POTENTIAL IMPACTS
INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, CHIMNEYS
TOPPLED, MOBILE HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED,
LARGE TREE TOPS AND BRANCHES SNAPPED OFF, SHALLOW-ROOTED TREES
KNOCKED OVER, MOVING VEHICLES BLOWN OFF ROADS, AND SMALL BOATS
PULLED FROM MOORINGS.
