with higher gusts. These winds are occurring over water off the
North Carolina coast. Ian is forecast to weaken further today
and dissipate by early Sunday.
Tropical-storm-force winds extend outward up to 275 miles (445 km)
east of the center over the Atlantic waters.
The estimated minimum central pressure based on surface observations
is 998 mb (29.47 inches).

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 still possible
over portions of North Carolina and southern Virginia early this
morning 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 through this morning, with minor river flooding possible
over Coastal Carolinas. Limited flooding is possible across
portions of the southern Mid-Atlantic over the weekend.
TORNADOES: A brief tornado remains possible through this 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.
