DISCUSSION AND OUTLOOK
At 1100 PM EDT (0300 UTC), the center of Hurricane Ian was located
near latitude 30.2 North, longitude 79.3 West. Ian is moving toward
the north-northeast near 10 mph (17 km/h). A turn toward the north
is expected early Friday, followed by a turn toward the
north-northwest with an increase in forward speed Friday night. On
the forecast track, Ian will approach the coast of South Carolina on
Friday. The center will move farther inland across the Carolinas
Friday night and Saturday.
Maximum sustained winds have increased to near 80 mph (130 km/h)
with higher gusts. Ian could strengthen a little more before
landfall tomorrow, and is forecast to rapidly weaken over the
southeastern United States late Friday into Saturday.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 415 miles
(665 km). A sustained wind of 58 mph (93 km/h) with a gust of 64
mph (104 km/h) was recently reported west of the center by a NOAA
and Saildrone Inc. research mission vessel.
The minimum central pressure reported by an Air Force Hurricane
Hunter aircraft is 986 mb (29.12 inches).
HAZARDS AFFECTING LAND
Key messages for Ian can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the
web at hurricanes.gov/text/MIATCDAT4.shtml.
STORM SURGE: The combination of storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...
* Edisto Beach to Little River Inlet...4-7 ft
* Flagler/Volusia County Line to Edisto Beach...3-5 ft
* Litter River Inlet to Cape Fear...3-5 ft
* Cape Fear River...2-4 ft
* St. Johns River...2-4 ft
* East of Cape Fear to Duck, including Pamlico and Neuse
* Patrick Air Force Base to Flagler/Volusia County Line... 1-3 ft
* Albemarle Sound...1-2 ft
The deepest water will occur along the immediate coast near and to
the right of the center, where the surge will be accompanied by
large waves. Surge-related flooding depends on the relative timing
of the surge and the tidal cycle, and can vary greatly over short
distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
WIND: Hurricane conditions are expected to begin in the
Hurricane Warning area starting early Friday, with tropical storm
conditions beginning overnight.
Tropical storm conditions are now occurring in parts of the warning
area on the northeast coast of Florida and should spread northward
along the Georgia and North Carolina coasts tonight through Friday.
Hurricane conditions are possible within the Hurricane Watch area in
North Carolina on Friday.
RAINFALL: Ian is expected to produce the following storm total
* Coastal Georgia: 1 to 2 inches.
* Northeast South Carolina: 4 to 8 inches, with local maxima of
* Central South Carolina, North Carolina, and southern Virginia:
3 to 6 inches with local maxima of 8 inches across northwest North
Carolina and southwest Virginia.
Major to record river flooding will continue across central Florida
through next week. Considerable flash and urban flooding, and minor
river flooding is possible across coastal and northeast South
Carolina Friday. Locally considerable flash, urban, and small
stream flooding is possible Friday into Saturday across portions of
northwest North Carolina and southwest Virginia. Limited flooding is
possible across portions of the southern Mid-Atlantic this weekend.
TORNADOES: Potential for a few tornadoes will begin late Friday
morning along a portion of the coastal Carolinas, spread inland
across eastern North Carolina during the afternoon and evening, and
shift into southeast Virginia overnight through early Saturday
SURF: Swells generated by Ian are affecting the northern coast
of Cuba, the northeastern coast of the Yucatan peninsula, Florida
and Georgia. Swells will increase along the coasts of South Carolina
and North Carolina. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
