SITUATION OVERVIEW
------------------
As of 5 AM EDT, Post-Tropical Cyclone Isaias was moving northward
across Alabama at 14 MPH with maximum sustained winds of 35 MPH.
Widespread and potentially significant impacts are starting to unfold
across North and Central Georgia on the eastern side of Isaias. These
include a prolonged period of strong winds, heavy rainfall with
localized flooding, and the potential for several tornadoes. Impacts
will peak in intensity today into tonight as Isaias continues moving
north across Alabama and into the Tennessee Valley.
While Isaias is weakening and has become post-tropical, there will be
a very strong pressure gradient between the system and strong high
pressure over the Mid-Atlantic. This gradient will support a prolonged
period of strong easterly winds with frequent gusts to 40 to 50 mph
across most of North Georgia through this afternoon and into tonight.
A High Wind Warning is in effect for this area. Areas to the south of
these warnings are in a Wind Advisory where winds will be weaker,
though gusts up to 40 mph will be possible. Across all areas, the
prolonged and strong winds could lead to power outages from downed
limbs and trees, especially when combined with saturated soils from
periods of heavy rain.
Isaias will continue to bring widespread rainfall to the area, with
multiple bands of heavy rain expected through early Sunday. Widespread
rainfall totals of 2 to 4 inches are likely across much of the area. A
localized swath of as much as 8 inches will be possible where the
heaviest banding sets up. This rainfall could lead to flash flooding,
particularly in urban and poor-drainge areas, as well as flood-prone
creeks and streams. The north-south orientation of bands may enhance
river flooding along north-south reaches. Training heavy rain in the
mountains may furthermore increase the risk of landslides. A Flood
Watch remains in effect for the entire area, as a result.
Additionally, a favorable environment for tornadoes is starting to
develop across Central Georgia early this morning, and will advance
into north Georgia by the afternoon and evening. Several tornadoes will
be possible, particularly within the outer rainbands of the system.
Tornadoes from tropical systems are typically quick to develop and
short-lived, but with the forward speed of the system and the unique
setup, we can't rule out a stronger (EF2 or EF3), long-track tornado,
especially across Central Georgia.
POTENTIAL IMPACTS
-----------------
* WIND:
Potential impacts from the main wind event are now unfolding across
North and Central Georgia. Remain well sheltered from hazardous wind
having potentially significant impacts. If realized, these 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.
* 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 extensive impacts. If
realized, these impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos, and
ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous. Many
road and bridge closures with some weakened or washed out.
* TORNADOES:
Potential impacts from tornadoes are still unfolding across North and
Central Georgia. Remain well braced against a dangerous tornado event
having possible 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.
