What happened

The episode as NWS JAX wrote it up.

Hurricane Ian made landfall as a powerful Category 4 Hurricane on the SW Florida peninsula coast near Punta Gorda on Wednesday, September 28th. The center tracked NE across south-central FL, north of Lake Okeechobee through Wednesday Night and then moved offshore of the central FL Atlantic coast Thursday Morning, September 29th, just near Cape Canaveral as a Tropical Storm. Ian regained Category 1 Hurricane Strength offshore of the northeast Florida Atlantic coast as it tracked NNE into Thursday Night and Friday morning as it made landfall along the South Carolina Atlantic coast. Locally, a strong nor'easter developed through the day Wednesday, September 28th, as a front lifted northward up the FL peninsula ahead of Ian. Tropical Storm force winds and bands of rainfall started to impact northeast Florida through the day Wednesday, the peak in local winds through the day Thursday as Ian's center tracked northward and offshore of the local Atlantic coast. Water levels increased within the St. Johns River basin Wednesday due to the strong nor'easter and annually high spring tides already created water level departures of 0.5 to 1 ft MHHW datum prior to the nor'easter further 'charging' the St. Johns River basin. The peak storm surge along the local Atlantic coast occurred Thursday, then the peak surge pressed into the St. Johns River basin Thursday night into Friday morning. Major to moderate tidal flooding continued into the weekend especially for Putnam, St. Johns and Flagler counties where trapped tides and northerly flow caused extended tidal flooding. Record setting rainfall occurred across the headwaters of the St. Johns River across east-central Florida, and water levels increased the week after Ian passed as the St. Johns River drains south to north, which was also leading up to the peak Spring tides between Oct 8th through Oct 11th.

.NEAR TERM...
(Through Friday Night)
Issued at 315 AM EDT Thu Sep 29 2022

While Tropical Storm conditions have been ongoing along the NE
FL/SE GA Coastal Counties, drier air mass has been drawn southward
across inland portions of SE GA/NE FL, with dew points falling
into the 30s/40s/50s and RH levels as low as 30-35% early this
morning. This is keeping the heavy rainfall confined to the
Atlantic Coastal counties and I-95 corridor and only pushing as
far inland as the St Johns River Basin. This trend will continue
over the next 24 hours as Ian slowly tracks towards the FL East
Coast and then tracks through the NE FL/SE GA Atlantic Coastal
waters tonight and Friday, before lifting Northward into the
Carolinas for Friday Night. Will likely stay the course with the
Flood Watch and Tropical Storm Warnings along the I-95 corridor
from SE GA south through NE FL and along the St Johns River Basin
while along the US 301 corridor in NE FL where the sharp edge of
heavy rainfall and winds end, may need to trim back on some of
these headlines as we move through the day today. Otherwise as the
system pulls northward through the Coastal Waters tonight, the
heavy rainfall will start to end from Southwest to Northeast
across the region, ending across inland NE FL late tonight, then
ending across the rest of the area early Friday. The winds will
take a bit longer to weaken on Friday as Ian tracks through the
coastal waters, but likely to see the end of Tropical Storm Force
wind gusts through the day. Temps will remain below normal through
the period with the widespread rainfall and north flow around Ian.
Temps remain below normal with highs only reaching around 70
degrees inland today and middle 70s along the coast. Another
cooler than normal day on Friday with highs in the upper 60s
across SE GA, but rebounding into the 70s across NE FL by the
late afternoon hours as rainfall ends and some clearing starts.

&&

.SHORT TERM...
(Saturday through Sunday night)
Issued at 315 AM EDT Thu Sep 29 2022

Post storm residual mid/level upper trough will be over the region
in the wake of Ian with much drier air air mass and precip free
with PWATS less than an inch in place over SE GA and NE FL. The
system will be over the inland Carolinas during the weekend in a
much debilitated residual storm then depression. Highs will in
the 80 to 85 degree range Saturday through Sunday, with lows upper
50s interior SE GA to mid 60s north central FL and coast by
Sunday.

&&

.LONG TERM...
(Monday through Wednesday)
Issued at 315 AM EDT Thu Sep 29 2022

Zonal flow will be in place Monday through Wednesday with a trailing
sfc trough axis or cold front working southward in the wake of
Ida with mainly dry weather in place through Wednesday. There may
be some isolated shower along the front and offshore waters but
not enough to mention showers over land areas in the forecast.
There will be beautiful weather with highs in the upper 70s to
lower 80s. Lows will be in the upper 50s SE GA and lower to mid
60s inland, with mid 60s coast.

&&

.AVIATION...
(06Z TAFS)
Issued at 1243 AM EDT Thu Sep 29 2022

Generally MVFR with pockets of IFR conditions expected through
the cycle for most local terminals as Hurricane Ian continues to
lift northeastward toward our region. Northerly or northeasterly
winds will gradually increase and remain gusty with the strongest
wind gusts (in some cases in excess of 45kts) possible for the
coastal terminals. Additionally, LLWS will be possible for several
local terminals. (Frye- LIX)

&&

.MARINE...
Issued at 315 AM EDT Thu Sep 29 2022

Hurricane Ian will track east-northeast across south central FL
Today, then north up the offshore waters Tonight through Friday
morning. The region will be in the trough behind the storm system
over the weekend into early next week.

Stay tuned to the National Hurricane Center for the latest updates
and plan accordingly. (Issued by JAX)

&&

.HYDROLOGY...
Issued at 315 AM EDT Thu Sep 29 2022

Hurricane Ian will continue to move very slow as the system
slides from south central Florida into east central Florida with a
decaying trend as the system moves closer the east coast of
Florida. Rainfall amount will be tempered with a more south and
east track with best threat

Tonight through Friday night...Rainfall totals of 5 to 10 inches
with locally higher amounts of 15 inches over eastern Putnam,
eastern Marion, Flagler and southeast St. Johns Counties with
trends markedly decreasing northwest of this immediate
precipitation axis to the North and west of this line. As a
result, most river levels that were forecast to go into moderate
and major levels will most likely be in action to minor stages due
to this shift.

As Saturday progresses the tropical moisture associated with Ian
will advect well northward as system moves into the Carolinas this
weekend.
