The episode as NWS MOB wrote it up.
Tropical Storm Cindy first developed in the central Gulf of Mexico on the afternoon of Tuesday, June 20th and made landfall between Cameron, LA and Port Arthur, TX during the early morning hours of Thursday, June 22nd. Despite the center of the storm being far removed from the north central Gulf Coast, the effects of Cindy extended several hundred miles to the east of the center and impacted the local area starting late Tuesday and persisting through the end of the week.
The primary impact across the western Florida Panhandle was from heavy rain and flooding. Storm total rainfall ranged from 5 to 10 inches across much of the western Florida Panhandle. The top rainfall report was from NAS Whiting Field which measured 9.46 inches. Based on radar estimates, up to a foot of rain likely fell in parts of eastern Santa Rosa County, but there were no gauge reports available from that area. The heavy rain resulted in periods of flash flooding.
Minor coastal flooding was observed, particularly on Highway 399 in Santa Rosa County. Maximum inundation was just above 2 feet MHHW based on the Pensacola Bay tidal gauge.
One EF-0 tornado occurred in southern Okaloosa County.

.PREV DISCUSSION... /issued 1136 PM CDT Tue Jun 20 2017/
DISCUSSION...See updated information for land and marine areas below.
UPDATE...A Tornado Watch is now in effect for all areas of
Northwest Florida...Mobile and Baldwin Counties in Alabama and
Stone and George counties in Southeast Mississippi until 10 AM CDT
Wednesday morning. Conditions have become more favorable for
thunderstorms capable of generating tornadoes. For tonight
continuing through most of wed morning expect increasing shear and
surface based instability as Tropical Storm Cindy continues to
move northward over the central gulf. A weak boundary mostly noted
in the moisture fields was also noted over the adjacent gulf
waters, generally stretching from east to west, moving northward
towards the coast. 32/ee
MARINE...The Tropical Storm Warning has been extended north over
Mobile Bay and the Mississippi Sound east of Pascagoula. Tropical
storm conditions have been noted over the lower half of Mobile
Bay and over the Mississippi Sound during the last couple of hours
and will likely continue through Wed. Expect winds from 25 to 35
knots with frequent gusts to 45 knots for most of the marine area
through Wed afternoon and possibly into Wed night.
A tornado watch is also in effect for the entire marine area until
10 AM CDT Wed morning. Conditions have become more favorable for
thunderstorms capable of producing tornadoes or waterspouts
through Wed morning. Special Marine warnings will be issued for
thunderstorms mainly capable of producing waterspouts during the
tropical storm conditions through Wed. 32/ee
PREV DISCUSSION... /issued 817 PM CDT Tue Jun 20 2017/
DISCUSSION...See updated information for land and marine areas below.
UPDATE...We are in the process of upgrading the Coastal Flood
Advisory for Mobile and Baldwin counties to a Coastal Flood
Warning. The Coastal Flood Advisory will continue for the western
Florida panhandle.
Minor to moderate coastal flooding will be possible around the
Mobile Bay area, especially around the times of high tide on
Wednesday morning and then even more so on Thursday morning.
Strong winds are expected to become increasingly more onshore
through Thursday keeping water levels high along the coast, and
combined with runoff from expected heavy rainfall, we could see 2
to 3 feet of water above normally dry ground along the Alabama
coast on Wednesday morning, and then 3 to 4 feet of water possible
above normally dry ground on Thursday morning. Some locations
along the coast around Mobile Bay had some minor flooding issues
today, and we expect more of the same and perhaps a little greater
impacts, especially around the times of high tide on Wednesday
and Thursday. for this reason we are upgrading to a Coastal Flood
Warning along the Alabama coast.
Further east along the coast of the western Florida panhandle, we
are expecting slightly lower possible inundation heights, with 1
to 3 feet of water above normally dry ground expected along the
coast. A Coastal Flood Advisory remains in effect for the western
Florida panhandle.
Along Gulf beaches of both Alabama and the western Florida
panhandle a High Surf Advisory remains in effect as well as a
High Risk of Rip Currents as dangerous surf conditions continue.
A Flash Flood Watch also remains in effect for southern portions
of the forecast area, generally along and south of Highway 84. 1.0
to 1.5 inches of rain has fallen across coastal portions of the
forecast area today, and an additional 2 to 3 inches is possible
tonight. Even more rainfall is expected Wednesday through Thursday,
with significant flash flooding becoming a possibility as we go
through the next couple of days.

SIGNIFICANT TO POTENTIALLY EXTREME HEAVY RAINFALL AND FLASH
FLOOD EVENT EXPECTED TO IMPACT LOCATIONS GENERALLY SOUTH OF
HIGHWAY 84 THROUGH THURSDAY EVENING...
NEAR AND SHORT TERM /Now Through Thursday/...Mid-afternoon
visible satellite imagery shows the circulation of now Tropical
Storm Cindy moving little over the west central Gulf of Mexico
this afternoon, while copious amounts of tropical moisture well to
the east of this feature continues to lift northward across much
of the eastern Gulf of Mexico and into our forecast area. In fact,
looking at the North Hemisphere view of satellite imagery, the
plume of tropical moisture extends all the way south to near
central America. Radar shows a solid shield of moderate to
locally heavy rain gradually lifting across the Gulf and into much
of our forecast area. Rainfall intensity should gradually ramp up
later this evening into late tonight as the deep tropical tap
continues to spread northward into the region, with the heaviest
rainfall looking to impact portions of southeast MS, southwest AL
and the northwest FL Panhandle.
Deep tropical moisture continues to spread northward Wednesday into
Wednesday night, as our region also becomes located within
difluent southerly mid level flow to the east of the low lifting
northwestward toward the northwest Gulf Coast. The end result will
be more widespread heavy rainfall continuing to spread into our
area through Wednesday night, locally very heavy at times as
precipitable water values increase to anomalously high ~2.5
inches. The potential for heavy rainfall and significant flash
flooding will continue through Thursday evening as a narrow plume
of tropical moisture continues to spread northward into the area
between Cindy in the vicinity of southeast TX and an upper level
ridge building westward into FL.
Significant to extreme rainfall amounts are likely through
Thursday, especially as you go closer to the coast, which may
result in areas to widespread flash flooding. We have included an
extreme flash flood potential in local graphics generally to the
south of a Janice, MS to Saraland, AL to Pensacola, FL line where
we think the potential of the heaviest rainfall of 5 to 10 inches,
with localized amounts of 10 to 15 inches will be possible. Flash
flood potential also is significant farther north to about the
Highway 84 corridor, where up to 3 to 6 inches of rainfall with
localized higher amounts are possible.
We will also need to monitor for isolated rotating cells capable
of producing brief tornadoes near the coast through Thursday as
they move ashore within the heavier rainfall bands.
High surf and risk of rip currents will continue through Thursday
with 6 to 9 feet breakers and a few breaker sets up to 10 feet,
before gradually subsiding to 5 to 7 feet by Thursday night. The
Coastal Flood Advisory continues into Thursday as 1 to 3 feet of
total inundation or water above normally dry ground can be
expected along low lying areas along the coast, especially during
times of high tide Wednesday and Thursday mornings. It should be
mentioned that the persistent fetch along with effects of any
excessive rainfall could exacerbate coastal flooding, especially
west of Pensacola and will monitor closely for potential needed
upgrades to Coastal Flood Warnings. /21
SHORT TERM /Thursday night Through Friday night/...The moisture
plume may gradually begin to shift westward with POPs becoming
more scattered late Thursday night into Friday as upper ridging
gradually builds westward. /21
LONG TERM /Saturday Through Tuesday/...An upper ridge building
west over the northern Gulf coast will bring a more direct southerly
flow. Increasing subsidence will bring a return of temps at or a bit
above normal into the weekend as a result. A surface front will move
towards the area late in the weekend, then stall over the forecast
area Sunday, bringing a bit of an increase in rain chances into the
coming week. This increase in the chance of rain will help to temper
the increased subsidence from the ridge and bring a return of below
seasonal temps, especially highs, for the beginning of the coming
week. /16
MARINE...TS Cindy sse of the marine area will continue to meander
nw towards se Texas. Swell and TS level winds will affect
unprotected waters the next 36hrs, then begin to slow settle into
the weekend. Settling will be in the slow side as a surface ridge
building west over the northern Gulf will create a tighter pressure
gradient, maintaining a moderate flow longer as winds become
southerly. /16
