PRECAUTIONARY/PREPAREDNESS ACTIONS...
Everyone should remain out of the water. Mariners should use extreme
caution, especially near inlets, cuts and bays. Swells approaching
these areas can lead to large, dangerous breaking waves. Keep a
clear distance away from the ocean. Structures such as piers and
jetties will be particularly treacherous.
If travel is required, allow extra time as some roads may be closed.
Do not drive around barricades or through water of unknown depth.

...HIGH SURF ADVISORY NOW IN EFFECT UNTIL 4 AM EDT FRIDAY...
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 2 PM EDT
THURSDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH THIS EVENING...
* LOCATIONS...Charleston, Beaufort and Coastal Colleton Counties.
* COASTAL FLOOD IMPACTS...One to two feet of saltwater inundation
above ground level is possible in low-lying areas near shorelines
and tidal waterways. Tides are expected to peak between 7.4 and 7.8
feet Mean Lower Low Water with the high tide this morning. This
will result in many roads becoming impassable and at least minor
flooding of properties. The risk for coastal flooding will continue
around times of high tide through Thursday as Hurricane Michael
passes through the area as a Tropical Storm.
* SURF ZONE IMPACTS...Up to 5 to 8 foot breaking waves and very
strong rip currents will be dangerous to anyone who enters the
surf.
* TIMING...High tide will occur around 930 to 1000 AM today at
Charleston. Saltwater inundation will be possible 2 hours before
and after high tide.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Everyone should remain out of the water. Mariners should use extreme
caution, especially near inlets, cuts and bays. Swells approaching
these areas can lead to large, dangerous breaking waves. Keep a
clear distance away from the ocean. Structures such as piers and
jetties will be particularly treacherous.
If travel is required, allow extra time as some roads may be closed.
Do not drive around barricades or through water of unknown depth.
Take the necessary actions to protect flood-prone property.
No one should enter the surf due to life threatening rip currents.
&&
Time of high total tides are approximate to the nearest hour.

Swells approaching these areas can lead to large, dangerous breaking waves. Keep a clear distance away from the ocean. Structures such as piers and jetties will be particularly treacherous. No one should enter the surf due to life threatening rip currents. && $$

Area forecast discussion, Oct 9, 11:17 AM EDT, 1 hour 6 minutes before
Area Forecast Discussion
National Weather Service Charleston SC
1117 AM EDT Tue Oct 9 2018
.SYNOPSIS...
Hurricane Michael will move north across the Gulf of Mexico
before making landfall along the Florida Panhandle Wednesday.
Michael will then weaken to a tropical storm as it moves
northest across Georgia and South Carolina Wednesday into
Thursday. Cooler high pressure will then build in through early
next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Grids and text products have been updated to reflect the 11 am
NHC Advisory. Made additional minor adjustments to hourly pops
based on latest radar data.
Shower activity associated with a ribbon of tropical moisture
located off the Florida east coast has been slow to move into
the area this morning. Activity should gradually move in from
the southeast through the afternoon as subtropical high pressure
located offshore of the Virginia Tidewater slowly propagates
farther offshore. Have lowered pops for much of the day,
increasing them back into the likely category across the far
southern zones by late afternoon. Extensive cloud cover and some
shower activity will help suppress high temperatures compared
to previous days. Mid 80s look reasonable for most locations.
Breezy conditions will persist at the beaches as the pressure
gradient tightens. The risk for gusty winds associated with the
approaching shower activity will increase through the day.
Could easily see wind gusts 40-45 mph with any robust shower
activity that forms. Limited instability will keep any risk for
tstm activity into the isolated category.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
Focused/onshore moisture transport pushing PWAT values well over
2 inches into the region justify likely/categorical PoPs
tonight. Locally heavy rainfall will be possible.
Based on the latest NHC forecast, Hurricane Michael will weaken to a
tropical storm as it moves across central GA Wednesday night and
through the SC Midlands Thursday. Mainly dry conditions expected
Friday as Michael departs off the NC Outer Banks.
Heavy Rainfall: Looks like one round of moderate to possibly heavy
rain will move through Wednesday, mainly in SC. Then rain chances
should increase from the southwest Wednesday night and continue
Thursday with increased intensity and this is when the best chance
for flash flooding should occur, especially in coastal areas around
times of high tide. Rainfall amounts should average 3-6 inches with
locally higher amounts possible.
Tornadoes: The forecast area is expected to remain in the favorable
right hand side of Michael and thus isolated, brief tornadoes are
possible. The greatest low-level instability is likely to be closer
to the coast while the greatest low-level helicity should be farther
inland closer to the core of the storm. The best chance of favorable
conditions lining up will be late Wednesday afternoon through
Thursday afternoon, with the threat ending earliest in GA on
Thursday.
Winds: Winds will ramp up Wednesday night in GA and then early
Thursday across SC coincident with Michael's closest approach.
Sustained tropical storm force winds of 35-40 mph with gusts near 50
mph are generally expected for most areas, mainly highest in
the stronger showers and storms.
Conditions should improve rapidly Thursday night.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
Late this week, surface high pressure will build back into the
region behind departing TC Michael. Precipitation potential is
looking rather low Friday and Saturday as a dry column sits
overhead, then rain chances will increase with increasing moisture
levels ahead of an approaching cold front Sunday into the first part
of next week. Temperatures look to remain above normal.
&&
.AVIATION /15Z TUESDAY THROUGH SATURDAY/...
Showers will produce periods of flight restrictions at KSAV and
KCHS just about any time through the 12Z TAF period. Remain
alert for amendments as dictated by near-term forecast trends.
Extended Aviation Outlook: Flight restrictions likely through
Thursday due to periods of moderate to heavy showers/tstms. Gusty
winds expected Wednesday night and Thursday as tropical
cyclone Michael moves northeast to the west of the terminals.
&&
.MARINE...
Today and tonight: Between strong high pressure to the north
and a coastal trough, east winds will gust to 25-30 knots, and
seas will average 4-7 ft near shore and 7-10 ft across outer
waters.
Wednesday through Sunday: Conditions will quickly deteriorate
Wednesday night into Thursday from south to north as tropical
cyclone Michael shifts northeast across inland GA/SC. Tropical storm
force winds are expected during this time with seas building to near
11 feet. Conditions are expected to rapidly improve late Thursday
before deteriorating a bit again this weekend as cooler/drier high
pressure builds in from the north leading to a tightening pressure
gradient.
Rip Currents: A high risk for rip currents has been issued for
all beaches due to persistent, strong onshore wind, some swell
and astronomical influences. The rip current risk will remain
elevated through the week.
&&
.TIDES/COASTAL FLOODING...
Minor to moderate tidal flooding is anticipated with the high
tide this morning. Minor to moderate tidal flooding will also
occur around the times of each high tide through Thursday.

Please listen to NOAA Weather Radio or go to weather.gov on the Internet for more information about the following hazards. Tropical Storm Watch. Coastal Flooding: High astronomical tides and onshore winds will likely lead to minor to moderate coastal flooding in low-lying tidal areas during both daily high tide cycles along the southern South Carolina and northern Georgia coasts through mid week. More significant flooding cannot be ruled out depending on the track and strength of Tropical Cyclone Michael. Also, if heavy rain falls around the times of high tide, significant flooding is possible in coastal areas. Rip Currents: Elevated onshore winds and swell waves should lead to an elevated risk along the southern South Carolina and northern Georgia coasts through late week. Heavy Rain: Heavy rain and localized flooding is possible, especially tonight through Thursday. Severe weather: Isolated tornadoes are possible Wednesday afternoon through Thursday. .SPOTTER INFORMATION STATEMENT... Spotter assistance is not anticipated at this time.
