The episode as NWS CHS wrote it up.
Colin first developed as a Tropical Depression just north of the Yucatan Peninsula on Sunday June 5th in the Gulf of Mexico. The system then tracked in a general north/northwest direction and strengthened into a Tropical Storm. Colin made landfall as a Tropical Storm during the night of June 6th near Keaton Beach, Florida before continuing northeast over northern Florida and then exiting off the southeast Georgia coast near Brunswick, Georgia during early morning hours on June 7th. The main impact from Colin was torrential rainfall across portions of southeast South Carolina and southeast Georgia. Storm total rainfall amounts between 3 to 4.25 inches generally occurred in many areas and resulted in flash flooding. Heavy rains along with high astronomical tides also produced approximately a 1 to 1.5 ft storm surge across coastal areas before the Tropical Storm shifted offshore and to the northeast.

Area Forecast Discussion
National Weather Service Charleston SC
1016 PM EDT MON JUN 6 2016
.SYNOPSIS...
Tropical Storm Colin will move across the Florida panhandle into
southern Georgia early tonight, then emerges off Georgia or South
Carolina coast early Tuesday morning. Colin will move away from
the region Tuesday afternoon as high pressure builds in from west
and persist through late in the week. Refer to the latest advisory
on Colin issued by the National Hurricane Center.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Radar and surface observations indicate the center of TS Colin was
located just offshore of Adams Beach, Florida. 07/02z mesoanalysis
showed a well-defined mesoscale warm frontal feature extending
east/northeast of the center to a position near Jacksonville,
Florida. Colin is on track to cross northern Florida tonight,
passing along or just offshore of the South Carolina and Georgia
coast early Tuesday.
A dry slow has been slowly working northeast into the area this
evening. Despite strong upper difluence from the right entrance
region of the upper jet and PWATS at or above record levels for
early June, the deepening dry air is beginning to erode the rain
shield and lowering hourly rainfall rates. Radar shows heavy
rainfall exiting the upper Charleston County coast while
additional heavy rains are reorganizing along the mesoscale warm
front where the best alignment of 850 hPA inflow and low-level
convergence is ongoing. As Colin moves northeast, the mesoscale
warm front is expected to become aligned off the lower South
Carolina coast. So, although rainfall rates are currently
diminishing, there are signals that another area of moderate to
heavy rain could reform along the coast after overnight along/to
the east of Colin's track. The flood threat will be heavily
dependent on where Colin's center eventually tracks, so if the
center passes even 10-15 miles farther to the east, the core of
the heaviest rains could very well miss land all together. Given
current radar trends and observed rainfall so far, the Flash Flood
Watch will be cancelled for Allendale, Screven, Jenkins, Bulloch,
Evans, Candler and Tattnall Counties.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
Tuesday: Colin will begin the day just east of Charleston, moving
rapidly northeast away from the area. Impacts will be quickly
diminishing after daybreak with the best rain chances during the
morning over far eastern areas. We show pops tapering off from
west to east with mainly dry conditions Tue afternoon. Skies will
be clearing during the day with inland areas mostly sunny most of
the day. Highs will reach the lower 90s inland with upper 80s to
around 90 closer to the coast. The strongest winds associated with
the tropical storm will be departing shortly after daybreak.
Wednesday through Thursday: Rather tranquil conditions expected as
high pressure settles over the area. The airmass will be
considerably drier than that which precedes it, as dewpoints drop
into the 50s over inland areas Wednesday and lower to middle 60s
elsewhere. Highs will be in the mid to upper 80s with no rain
expected.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The long term will continue the mostly tranquil weather. Models are
in good agreement slowly moving a trough off of the east coast while
a ridge strengthens over the Plains. Surface high pressure initially
over the OH and TN valleys is forecasted to move offshore Friday and
Saturday while another high develops over the Lower Mississippi
Valley. Temperatures will gradually increase each day. Afternoon sea
breeze showers and thunderstorms appear to return over the
weekend.
&&
.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
MVFR or IFR conditions will occur through late tonight or early
Tuesday in response to Tropical Storm Colin that will draw closer
to the area this evening, passing nearby during tonight, before
lifting quickly away during the mid and late Tuesday morning
hours. VFR conditions will make a return by late morning and into
the afternoon on Tuesday as the system pulls northeast and out of
the area.
Mostly steady moderate to occasional heavy rains will continue at
both airfields tonight. Winds will become southeast and east
early tonight, then back around to the northeast late tonight as
speeds strengthen in proximity to Colin as it passes nearby. Rain
will taper off and end Tuesday morning as winds drop off
considerably. Any slight deviation in the future track of Colin
could result in a considerable deviation from exactly how the
winds shift through the night.
While there can be a little thunder and lightning can occur at
both terminals at most any time, probabilities are too low to
include at the moment.
There is also the risk of LLWS (low level wind shear) during
tonight, but given that any slight deviation in the track of the
tropical storm could change surface and low level winds
considerably, we have chosen not to include with the 00z TAF set.
Extended Aviation Outlook: VFR weather will persist through
Saturday.
&&
.MARINE...
Tonight: Dangerous marine conditions will impact the local waters
as Tropical Storm Colin moves toward and eventually through the
area. Solid tropical storm force winds are expected for all
marine legs, which also include Charleston Harbor, with shifting
winds reaching as high as 30-40 kt. Gusts to 50 kt will be
possible closer to the center of Colin. As a result a Tropical
Storm Warning remains in effect for all waters.
Keep in mind that prior to the circulation of Colin moving in late
this evening and overnight, any stronger storm clusters or cells
can produce winds in excess of 35 or 40 kt, similar to what
occurred at KSSI around 5 pm.
Generally used a 50/50 blend of NWPS and WaveWatch output to
construct seas. Based on this, seas are forecast to reach 7 to 11
ft nearshore waters and as high as 12 to 15 ft over the offshore
waters. Even 3 to 4 foot waves will develop in Charleston Harbor.
These wave heights could be conservative, but given the poor
structure of Colin we haven't deviated too much from earlier
forecasts.
Waterspouts remain a distinct possibility with 0-1 km Helicity of
100-150 m2/sec2 and 0-1 km Bulk Shear of 25-30 kt. The Supercell
Composite however is less favorable than earlier in the day.
All mariners are urged to remain in port due to the extremely
hazardous conditions.
Tuesday: Winds die down quickly as Colin lifts northeast away from
the area. Seas will gradually subside through Tuesday night.
Winds/seas not expected to exceed advisory levels Wednesday
through Saturday.
Rip Currents: Due to minimal swell and an offshore wind, the risk
is low on Tuesday, but given potential lingering effects of Colin,
please use extreme care if you opt to go into the surf, and
remember that rip currents even during a low risk can still occur.

.TIDES/COASTAL FLOODING...
Coastal flooding is currently in progress along the coast.
A Coastal Flood Advisory has not be issued since a Tropical Storm
Watch is already in effect. Impacts from coastal flooding will be
included in the Tropical Storm Colin Local Statement (HLS) as well
as the Colin Local Watch/Warning Statement (TCV).
