Post-Tropical Cyclone Ian Discussion Number 34
NWS National Hurricane Center Miami FL AL092022
1100 PM EDT Fri Sep 30 2022
Ian has a classic comma-shaped cloud pattern of an extratropical
cyclone in satellite imagery. The radar structure of the system has
degraded tonight, but surface observations indicate the center of
Ian is moving northward across the central portion of North
Carolina. The initial intensity is lowered to 45 kt for this
advisory, which is consistent with the latest Decay-SHIPS guidance
and some marine observations offshore of the Cape Fear region that
indicate sustained tropical-storm-force winds are still occurring
Ian is still moving northward at about 13 kt. This general motion is
expected to continue through Saturday, which will bring Ian across
the central portions of North Carolina and Virginia on Saturday.
Continued weakening is forecast, and the cyclone is expected to
dissipate by early Sunday. There were no notable changes made to the
NHC track or intensity forecast.
Because recent observations indicate that wind speeds over land have
diminished, the Tropical Storm Warning has been discontinued for the
coasts of South Carolina and North Carolina. Similarly, coastal
water levels have receded below warning criteria along the coast of
North Carolina, and the Storm Surge Watches and Warnings there have
also been discontinued. However, heavy rain and gusty winds are
expected to continue into tomorrow morning across portions of the
Carolinas and Mid-Atlantic states.
Even though all tropical watches and warnings have been
discontinued, intermediate advisories will still be issued as long
as Ian continues to produce winds of tropical storm strength.
1. Gusty winds are expected through early Saturday over portions of
South Carolina and North Carolina.
2. Ongoing major to record river flooding will continue through next
week across portions of central Florida. Considerable flooding is
possible across portions of the Carolinas and southeast Virginia.
Locally considerable flooding is possible across portions of
northwest North Carolina and southern Virginia tonight into early
