Post-Tropical Cyclone 09L (Ian)

HEAVY RAIN, FLASH FLOODING, AND GUSTY WINDS CONTINUE AS IAN MOVES INLAND OVER NORTH CAROLINA

NHC Advisory number 34

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.

HAZARDS AFFECTING LAND

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.

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.

>>> Eastern Tropical Atlantic:

A tropical wave is producing disorganized showers and thunderstorms over the far eastern tropical Atlantic.

Environmental conditions are forecast to be conducive for gradual development of this system, and a tropical depression is likely to form during the early part of next week while the system moves generally west-northwestward over the eastern tropical Atlantic.
