SITUATION OVERVIEW
------------------
Helene has made landfall as a Category 4 hurricane in the Big Bend
region of Florida as of 11 PM EDT. Helene will be an expansive
system with impacts occurring well away from the storm center. Due
to the intensity and fast forward motion, unprecendented wind and
flooding impacts, rivaling or exceeding those of Hurricanes Opal
(1995), Irma (2017) and Michael (2018), are expected across the
north and central Georgia.
Several areas have already received 4 to 8 inches of rain in the
last 24 hours. Additional rainfall amounts of 2.5 to 5 inches, with
localized higher amounts, are expected. The highest total amounts
will occur over a wide swath paralleling I-85 into northeast and
east central Georgia. Widespread flooding is expected with
significant flash flooding and moderate to major river flooding
possible. A few flash flood warnings have already gone into effect.
Tropical storm and hurricane force wind gusts, potentially exceeding
80 mph, are expected to begin across the southern portion of the
forecast area, then quickly spread north overnight into Friday
morning. Hurricane Force wind gusts will be possible for some
locations including the Atlanta Metro extending eastward to Athens
and in the higher terrain of the northeast Georgia mountains.
Outside of these locations, Tropical Storm force gusts are expected
all the way up to the border with Tennessee and North Carolina.
Given the saturated soils, widespread downing of trees and
significant power outages are expected. Be ready for an extended
period of power loss!
A few short-lived tornadoes have already occurred this evening. Short-
lived tornadoes remain possible across east-central Georgia
overnight through early Friday morning, with the greatest potential
over areas north and east of the track of Helene.
The time to hunker down and take shelter is now!
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
north and central Georgia. Remain well guarded against life-
threatening flood waters having possible devastating impacts. If
realized, these 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:
Potential impacts from the main wind event are expected early Friday
morning before sunrise in central Georgia. Remain well sheltered from
life- threatening wind having extensive impacts. If realized, these
impacts include:
- Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and
roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. Several bridges, causeways, and
access routes impassable.
- Large areas with power and communications outages.
Potential impacts from the main wind event are also expected across
north Georgia. Remain well sheltered from dangerous wind having
significant impacts.
* TORNADOES:
Potential impacts from tornadoes are still unfolding across portions of
east-central Georgia. Remain well braced against a dangerous tornado
event having significant impacts. If realized, these impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a battery-
powered radio, charged cell phone and flashlight handy.
During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.
Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.
If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
Do not venture outside while in the eye of a hurricane as any
improvement in weather will only be temporary. Once the eye passes,
conditions will become life threatening as winds immediately return
to dangerous speeds, so remain safely sheltered from the storm.
Do not be a thrill seeker or risk your life for senseless photos or
videos.
