338 PM EDT Wed Sep 16 2020

.SHORT TERM /Tonight through Thursday Night/...

Recently-downgraded Tropical Storm Sally will be the big focus
through the next 24 hours or so as it has begun its northeastward
track toward the forecast area. The rain shield from Sally will
continue to overspread the area this evening into tonight with the
most concerning rainfall rates expected to pick up after 00z as
the center of Sally approaches. These high rainfall rates in the
bands of Sally are expected to quickly increase flash flooding
potential by late evening into overnight. The axis of heaviest
expected heaviest rainfall has continued to nudge a bit southward
as compared to the morning forecast courtesy of the slightly
farther south forecast track of Sally, generally along and near a
Columbus to Macon to Athens line. Widespread 3-6" rainfall totals
with localized higher amounts are expected in this area with
amounts tapering farther northwest and southeast.

The tornado risk this afternoon remains south of the area where
favorable conditions are situated. This will slowly change through
the evening and overnight as higher dewpoints in the 70s creep
northward into central Georgia. Thus, the risk for tornadoes will be
on the increase from late evening and overnight through Thursday
morning in central and east-central Georgia, shifting eastward into
the Carolinas by midday.

The other threat to consider from this evening into the overnight
will be increasingly gusty winds. While wind gusts will continue to
be on the downtrend as the system weakens, sufficient wind energy
will remain such that sustained winds 15-25 mph and gusts perhaps as
high as 35-40 mph are expected. Given the heavy rainfall and
saturated soils, a Wind Advisory was issued for much of the area
through 10 AM Thursday. Scattered downed trees and power outages are
expected, even in areas where Wind Advisory criteria isn't quite
reached.

By midday Thursday into the afternoon, the heaviest rainfall will
shift east of the forecast area as the remnants of Sally depart.
Lingering showers will remain, but any additional QPF will remain
light.

RW

.LONG TERM /Friday through Wednesday/...

Still some slight timing differences between the GFS and ECMWF for
Friday. The GFS is faster with getting the remnant low associated
with Sally out of the Carolinas, while the ECWMF hangs onto it a bit
longer. This will potentially impact the progression of a southward
moving cold front Friday into very early Saturday.

The front is expected to hang/very slowly move south across southern
portions of the CWA for Friday into early Saturday. Strong high
pressure will begin building in from the north later on Saturday and
should remain in control of the sensible weather for the remainder
of the long term portion of the forecast.

Temperatures will remain below normal for the weekend through early
next week. Daytime highs will average 10 to 15 degrees below normal.
Overnight mins will average 5 to 10 degrees below normal.

.HYDROLOGY...

While the axis of expected heaviest rainfall has been
nudged a bit farther south this afternoon as compared to this
morning, the overall forecast remains largely unchanged. Widespread
totals of 3 to 6 inches remain forecast generally along and near a
Columbus to Thomaston to Macon to Madison to Athens line, with
locally higher amounts possible. The areal extent of the Flash Flood
Watch thus remains unchanged, generally incorporating areas forecast
to see at least 2 inches of rainfall. Flooding will likely linger on
some rivers, creaks, and streams beyond the end of the watch period.

&&

.AVIATION... 18Z Update... Widespread IFR conditions prevail
through much of the TAF period as Sally moves toward the area with
LIFR possible, especially after 00z. Widespread rain will
overspread the area with +ra expected, especially after 00z and
through early Thurs morning. Embedded isolated tsra is possible,
mainly at MCN/CSG overnight. Wind speeds will increase
appreciably, sustained as high as 20-25kts during the 00-06z
period with gusts as high as 30-35 kts. Direction will remain
easterly, shifting W Thurs afternoon.

//ATL Confidence...18Z Update...
High confidence.

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...Today and Tonight...

A Flash Flood Watch has been issued for much of north and central
Georgia through Friday. As the remnants of Hurricane Sally move
across the deep south, very heavy rainfall is likely for much of
the outlook area, especially within the outer rainbands. Runoff
associated with the heavy rains could produce flash flooding and
river flooding.

In addition to heavy rainfall, the outer rainbands associated with
Sally will contain stronger winds gusts capable of producing
downed trees and powerlines. A couple of brief weak tornadoes
cannot be ruled out.

A Wind Advisory may be needed for much of north and central
Georgia later today and into the overnight hours. Outside of the
rainbands, sustained winds of 15 to 25 mph with gusts up to 35
mph are possible.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

The Flash Flood Watch will continue through early Friday morning
as the remnants of Sally move across Georgia. Within the stronger
rainbands, damaging wind gusts and weak brief tornadoes will
continue to be possible.

Sustained winds of 15 to 25 mph with gusts up to 35 mph may
continue into Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected through tonight.

The people who died

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.

Event	Date	Age	Sex	Where	Kind
Strong Wind, North Fulton	2020-09-16	30	Male	Permanent Home	Direct
Strong Wind, Gwinnett	2020-09-17	71	Female	Outside/Open Areas	Direct

What these are

Strong Wind: Non-thunderstorm winds below high wind criteria that nonetheless caused damage or casualties.
Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
