Hurricane Isaias Impacts on North and Central GA:
From Friday night through Sunday,
Hurricane Isaias will
make
landfall over the Gulf Coast and then weaken as it moves
northward across Mississippi and Alabama into the TN Valley. North
and Central Georgia will be on the `dirty` side of the storm, and
potentially see significant impacts with a prolonged period of
strong winds, heavy
rainfall with localized
flash flooding, and a
few tornadoes.
Strong Winds:
As Isaias moves inland Friday night into Saturday, its
wind field
will expand considerably, with strong winds extending well east of
the center of the storm into West-Central GA. A
Tropical Storm
Watch is in effect for this area where wind gusts of 40 to 50 mph
will be possible. Further north/east, while Isaias will be
weakening and becoming post-tropical, there will be a very strong
pressure
gradient between it and 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 from early Saturday through early Sunday. A High
Wind
Watch has been issued for this area. The prolonged and strong
winds could lead to
numerous power outages from downed limbs and
trees, especially when combined with saturated soils from periods
of heavy rain.
Heavy
Rainfall:
As Isaias moves northward through Mississippi/Alabama, it will
bring widespread
rainfall and multiple bands of heavy rain across
the area Friday night through Sunday.
Rainfall totals of 1 to 3
inches are
likely across much of the area, with localized amounts
up to 5 inches possible. High
rainfall rates (
PWAT values of
2-2.3") and repeated rounds of heavy rain could lead to localized
flash flooding, particularly in urban and poor-drainge areas, as
well as
flood-prone creeks and streams. A
Flood Watch has been
issued for the entire area.
Tornadoes:
As Isaias tracks northward and inland on Saturday, a favorable
environment for tornadoes will develop across North and Central
Georgia, potentially lingering into Sunday morning. Several
tornadoes will be possible during this period, including the
overnight hours Saturday night. 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. It is imperative
that everyone has a way to receive
tornado warnings.
Warm and Dry In the
Wake of Isaias:
On the backside of Isaias` remnants, a mid- level
ridge will build
over the Southeast US, bringing a warm and dry airmass into the
area. Rain chances will drop to near zero for Monday- Wednesday,
with low temps in the upper 50s to low 60s, and high temps in the
low to mid 80s.
