SITUATION OVERVIEW
------------------
TROPICAL STORM HELENE CONTINUES TO MARCH NORTHWARD THROUGH EASTERN
GA WITH IMPACTS EXTENDING WELL OUTSIDE OF THE CENTER OF THE STORM.
HELENE'S FAST FORWARD SPEED WILL ALLOW STRONG, DAMAGING WINDS,
ESPECIALLY IN GUSTS, TO PENETRATE WELL INLAND ACROSS THE SOUTHEASTERN
UNITED STATES.
TROPICAL STORM WIND GUSTS AROUND 60 MPH WILL BE POSSIBLE THROUGH MID
MORNING AS HELENE MOVES WEST OF THE AREA. TORNADOES WILL ALSO BE
POSSIBLE WITH HIGHEST CONFIDENCE ALONG AND SOUTH OF I-20 THROUGH
FRIDAY MORNING.
POTENTIAL IMPACTS
-----------------
* WIND:
PROTECT AGAINST DANGEROUS WIND HAVING POSSIBLE SIGNIFICANT IMPACTS
ACROSS THE AUGUSTA METRO AREA AND THE CSRA. POTENTIAL IMPACTS IN THIS
AREA INCLUDE:
- SOME DAMAGE TO ROOFING AND SIDING MATERIALS, ALONG WITH DAMAGE
TO PORCHES, AWNINGS, CARPORTS, AND SHEDS. A FEW BUILDINGS
EXPERIENCING WINDOW, DOOR, AND GARAGE DOOR FAILURES. MOBILE
HOMES DAMAGED, ESPECIALLY IF UNANCHORED. UNSECURED LIGHTWEIGHT
OBJECTS BECOME DANGEROUS PROJECTILES.
- SEVERAL LARGE TREES SNAPPED OR UPROOTED, BUT WITH GREATER
NUMBERS IN PLACES WHERE TREES ARE SHALLOW ROOTED. SEVERAL
FENCES AND ROADWAY SIGNS BLOWN OVER.
- SOME ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
OR HEAVILY WOODED PLACES. A FEW BRIDGES, CAUSEWAYS, AND ACCESS
ROUTES IMPASSABLE.
- SCATTERED POWER AND COMMUNICATIONS OUTAGES, BUT MORE PREVALENT
IN AREAS WITH ABOVE GROUND LINES.
* TORNADOES:
PROTECT AGAINST A PARTICULARLY DANGEROUS TORNADO EVENT HAVING
POSSIBLE EXTENSIVE IMPACTS ACROSS THE REGION, ESPECIALLY SOUTH AND
EAST OF I-20. POTENTIAL IMPACTS INCLUDE:
- THE OCCURRENCE OF NUMEROUS TORNADOES CAN GREATLY HINDER THE
EXECUTION OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- MANY PLACES MAY EXPERIENCE TORNADO DAMAGE WITH A FEW SPOTS OF
IMMENSE DESTRUCTION, POWER LOSS, AND COMMUNICATIONS FAILURES.
- LOCATIONS COULD REALIZE ROOF AND WALL FAILURES OF STURDY
BUILDINGS WITH SOME BEING LEVELED, STRUCTURES UPON WEAK
FOUNDATIONS BLOWN AWAY, MOBILE HOMES OBLITERATED, LARGE TREES
TWISTED AND SNAPPED WITH FORESTED TREES UPROOTED, VEHICLES
LIFTED OFF THE GROUND AND THROWN, AND SMALL BOATS DESTROYED.
LARGE AND DEADLY PROJECTILES CAN ADD TO THE TOLL.
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
DEVASTATING IMPACTS ACROSS THE CSRA AND SOUTH/CENTRAL MIDLANDS.
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.
PREPARE FOR RAINFALL FLOODING HAVING HIGH TO MODERATE IMPACTS ACROSS
THE MIDLANDS AND PEE DEE.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
IF A TORNADO WARNING IS ISSUED FOR YOUR AREA, BE READY TO SHELTER
QUICKLY, PREFERABLY AWAY FROM WINDOWS AND IN AN INTERIOR ROOM NOT
PRONE TO FLOODING. IF DRIVING, SCAN THE ROADSIDE FOR QUICK SHELTER
OPTIONS.
KEEP CELL PHONES WELL CHARGED. CELL PHONE CHARGERS FOR AUTOMOBILES
CAN BE HELPFUL, BUT BE AWARE OF YOUR RISK FOR DEADLY CARBON MONOXIDE
POISONING IF YOUR CAR IS LEFT IDLING IN A GARAGE OR OTHER POORLY
VENTILATED AREA.
RAPIDLY RISING FLOOD WATERS ARE DEADLY. IF YOU ARE IN A FLOOD-PRONE
AREA, CONSIDER MOVING TO HIGHER GROUND. NEVER DRIVE THROUGH A FLOODED
ROADWAY. REMEMBER, TURN AROUND DON'T DROWN!
IF IN A PLACE THAT IS VULNERABLE TO HIGH WIND, SUCH AS NEAR LARGE
TREES, A MANUFACTURED HOME, UPPER FLOORS OF A HIGH-RISE BUILDING, OR
ON A BOAT, CONSIDER MOVING TO A SAFER SHELTER BEFORE THE ONSET OF
STRONG WINDS OR FLOODING.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO OR LOCAL NEWS OUTLETS
FOR OFFICIAL STORM INFORMATION. BE READY TO ADAPT TO POSSIBLE CHANGES
TO THE FORECAST. ENSURE YOU HAVE MULTIPLE WAYS TO RECEIVE WEATHER
WARNINGS.
