The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Sep 30, 10:10 AM EDT, 27 minutes before
Area Forecast Discussion
National Weather Service Charleston SC
1010 AM EDT Fri Sep 30 2022
.SYNOPSIS...
Hurricane Ian is expected to bring impacts to the area through
tonight. A drier and cool air mass is expected this weekend
through early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
The forecast has been updated to account for a tighter gradient
between where steady moderate to heavy rains will occur, mainly
over the Charleston Quad-County region and Beaufort County, to
where we have little to no rain over much of our Georgia zones.
We removed mention of t-storms from all but the Charleston Tri-
County which will be in closest proximity to the track of Ian.
The most immediate concern will be the main band northwest of
Ian that will impact Charleston and Berkeley County and maybe a
portion of Dorchester County with hurricane force winds and
intense rains and a few t-storms. There could be a quick 3 to 5
inches in some places into early afternoon resulting in flash
flooding. This includes downtown Charleston and surrounding
locations. There will be trees and powerlines down as well.
Satellite imagery showing that Ian is taking on more of an
extra-tropical or hybrid appearance with an occluded low and a
cold front that stretches south to the Bahamas. The system is
being kept from moving onshore just yet due to the fact that it
is not a "pure" hurricane, with the cool and wet pre-existing
air mass in place. Plus Ian is feeding off the Gulf Stream and
is in proximity to the associated baroclinic zone.
Temps and dew points are very fall like and will stay far below
climo through the day. We have adjusting the grids to show
cooler temps, both hourly and for max values.
Previous discussion...
Sunrise update: Rainbands continue to push onshore and a Flash
Flood Warning has been issued for Downtown Charleston and
surrounding areas until noon. There have been numerous reports
of road closures. As for the forecast, updated temperatures and
dewpoints with current observations. Otherwise, the forecast is
on track.
Today: Hurricane Ian (refer to the latest NHC advisories regarding
the track/intensity of Ian) will approach the region this morning
then make landfall sometime this afternoon. With the approach,
moderate to heavy bands of rainfall will gradually encompass the
area. One of the concerns of the day will be the possibility of
flooding. The highest rain amounts will occur across the Charleston
Tri-county with 3-7 inches possible. Further south, drier air will
keep rain chances lower with only 1-3 inches can be expected. As
typical, locally higher rainfall amounts will be possible. If
heavier bands set up over the same area throughout the day, flooding
could be exacerbated. The intense rainfall rates combined with
periods of storm surge could cause significant flooding near/around
tidal areas. WPC has outlooked portions of southeast South
Carolina in a moderate risk of excessive rainfall. A Flood Watch
will remain in effect for most of our SC counties and for
Chatham county. Aside from the rainfall, winds will be quite
gusty as Hurricane Ian is forecast to make landfall as a
Category 1. This will lead to breezy conditions throughout the
day, especially on bridges and elevated buildings. A Hurricane
Warning is in effect for coastal SC counties. A Tropical Storm
Warning has also been issued for portions of SE SC/GA as there
is some concern that mixing will occur as Hurricane Ian shifts
inland. Therefore, winds could exceed 40 mph at times.
Otherwise, it will be cloudy and cool. Highs will be in the mid
60s to low 70s.
Tonight: Hurricane Ian will shift away from the area late
tonight and conditions should quickly improve. Winds are
expected to quickly diminish by midnight. Similarly, any
lingering precipitation should dissipate around the same time.
Overnight, cloud cover will depart the region, leaving the area
with decent radiational cooling, allowing for lows to be in the
mid 50s to low 60s.
&&
.SHORT TERM /SATURDAY THROUGH MONDAY/...
A strong mid-level trough will persist along the Eastern third of
the country through Sunday, with an embedded cut-off low hovering
near the middle Appalachians. The low will shift towards the Mid-
Atlantic on Monday while the trough weakens. At the surface, the
remnants of Ian will be to our north on Saturday and moving away,
while a weak front moves through our area, then offshore Saturday
night. The weak front will linger further offshore through Monday
while high pressure gradually builds in from the west and northwest.
Models indicate that remnant moisture from Ian should stay well to
our north through Monday, and any additional moisture associated
with the front will stay should also stay far offshore. Therefore,
dry conditions are expected to persist. High temperatures will be at
or slightly below normal Saturday and Sunday, then falling well
below normal on Monday. Due to the dry air mass and mostly clear
skies, decent radiational cooling should yield low temperatures well
below normal Saturday night and Sunday night.
&&
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
Surface High pressure will build in from the northwest Monday night
through Wednesday, then shift offshore on Thursday. The High will
bring our area dry conditions. Temperatures will remain well below
normal. Though, highs are expected to trend warmer each day.
&&
.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
Conditions across KJZI, KSAV and KCHS have deteriorated and
flight restrictions will prevail through much of the day. As
Tropical Cyclone Ian approaches, extensive cloud cover and
moderate to heavy rainbands will move onshore, leading to IFR to
LIFR conditions for much of the morning at KCHS/KJZI. By late
afternoon, conditions should start to improve and VFR is
expected to return by 04Z Saturday.
Extended Aviation Outlook: VFR.
&&
.MARINE...
Today: Hurricane Ian will move across the waters throughout the
morning producing hazardous marine conditions across all waters,
including the Charleston Harbor. Hurricane force winds will be
possible and a Hurricane Warning will remain in effect. Seas will be
10-15 feet in the nearshore waters with 15-20 feet in the outer
Georgia waters. Once Ian makes landfall, conditions will gradually
improve into the overnight.
Extended Marine: Conditions will gradually improve Saturday as the
remnants of Ian continue to move north of the area and a weak cold
front moves offshore overnight. A weak front will remain offshore
early next week while High pressure persists to our northwest.
Conditions are expected to remain below Small Craft Advisory
criteria.
Marine Impacts: High risk for rip currents expected along all area
beaches Friday. Conditions on Friday into Friday night along all
beaches may lead to High Surf (5 to 8 ft breakers) and Beach
Erosion. There will be both a High Risk for rip currents and a High
Surf Advisory in effect through Friday. A moderate risk for rip
currents is expected for Saturday, with lingering long swell periods
and 3-4 ft breakers.
&&
.HYDROLOGY...
High resolution guidance indicates that a band of convection will
rotate ahead of the center of Ian Friday morning. In fact, it
appears that the convection will pivot across the CHS Tri-county,
resulting in 4 to 7 inches of rain falling generally during the
daylight hours. The intense rainfall rates combined with
periods of storm surge could cause significant flooding near
around tidal areas. The most persistent rain bands are expected
to remain east of the I-95 corridor. However, the greatest
rainfall amounts will remain along and north the center of Ian,
leading to the heaviest rainfall and intense rainfall rates over
the CHS Tri-county, where some areas could see localized
amounts in excess of 8 inches.
&&
.TIDES/COASTAL FLOODING...
Significant coastal flooding is expected to continue with the
Friday morning high tide as Hurricane Ian impacts the area,
especially along the Charleston and Colleton county coasts. The
offshore flow and much less rain south of Beaufort County will
cause very little in the way of coastal flooding.
The rainfall may overlap with periods of significant coastal
flooding/storm surge, exacerbating any fresh or salt water flooding.
