was located near latitude 35.3 North, longitude 79.5 West. The 
post-tropical cyclone is moving toward the north near 15 mph (24 
km/h). This general motion with a decrease in forward speed is 
expected through Saturday as Ian moves farther inland across central 
North Carolina and Virginia.

Maximum sustained winds have decreased to near 50 mph (85 km/h) with 
higher gusts. These winds are occurring over water off the Carolina 
coast.  Ian is forecast to weaken through Saturday and dissipate by 
early Sunday.

Tropical-storm-force winds extend outward up to 195 miles (315 km)
from the center.

The estimated minimum central pressure is 994 mb (29.36 inches) 
based on surface observations.

STORM SURGE: Surge related flooding will continue to recede along
portions of the North Carolina coast, including the Pamlico Sound
and Neuse River as well as the Albemarle Sound. For information
specific to your area, please see products issued by your local
National Weather forecast office.

WIND:  Wind gusts to tropical storm force are expected to continue
over portions of North Carolina and South Carolina overnight as Ian
moves farther inland.

RAINFALL: Ian is expected to produce 3 to 6 inches, with local
maxima of 8 inches across portions of North Carolina, West Virginia,
and the southern Mid-Atlantic states.

Major to record river flooding will continue across central Florida
through next week.  Considerable flash, urban and small stream
flooding is possible across portions of North Carolina and southern
Virginia tonight into early Saturday, with minor river flooding
possible over Coastal Carolinas. Limited flooding is possible across
portions of the southern Mid-Atlantic this weekend.

TORNADOES:  A brief tornado remains possible through early Saturday
morning across far southeast Virginia and the southern Delmarva
Peninsula.

SURF:  Swells generated by Ian and a nearby frontal system are
affecting the east coast of Florida, Georgia, the Carolinas, and the
northwestern Bahamas. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
