Tropical Storm Ian Discussion Number 28
NWS National Hurricane Center Miami FL AL092022
1100 AM EDT Thu Sep 29 2022

The center of Ian has emerged into the western Atlantic Ocean to
the north of Cape Canaveral. While satellite images show the
system is becoming a hybrid cyclone, with frontal features outside
of the core of Ian, the winds from multiple sources are notable.
Velocity data from NWS Doppler radar indicate maximum winds of about
70-75 kt at 10,000 ft over land, and sustained winds of about 55 kt
were recorded in the Daytona Beach area earlier this morning. These
data support a higher initial intensity, now 60 kt for this

The storm is moving northeastward at about 8 kt. Ian has stubbornly
gone east of the track forecast for the past couple of days and has
moved back over water faster than expected. A mid-level shortwave
trough moving southward across the southern United States should
turn Ian northward overnight and north-northwestward on Saturday.
The official track forecast is shifted to the east, consistent with
the latest consensus guidance.

Ian should move over the Gulf Stream tonight and tomorrow for a
longer period of time than previously anticipated, which should
maintain Ian's central convection. Additionally, an increased
pressure gradient on the northwestern side from a stationary front
near the southeastern US, should provide a boost to the wind speeds
on that side of the storm. We now expect Ian to become a hurricane
again by this evening. As the system approaches South Carolina, Ian
should maintain this intensity, and Hurricane Warnings have been
issued for the entire coast of South Carolina. This scenario is
consistent with the global and regional hurricane model guidance.
It is worth noting that Ian is forecast to have atypical structure
when it nears the southeastern United States, and strong winds will
extend well ahead of the center, even on the northwestern side.

Key Messages:

1. There is a danger of life-threatening storm surge through Friday
along the coasts of northeast Florida, Georgia, and South Carolina.
Residents in these areas should follow any advice given by local

2. Hurricane-force winds are expected across the South Carolina
coast beginning early Friday, where a Hurricane Warning has been
issued. Hurricane conditions are possible by tonight along the
coasts of northeastern Florida and Georgia, where a Hurricane Watch
is in effect. Preparations should be rushed to completion since
tropical-storm-force winds will begin well before the center
approaches the coast.

3. Ongoing major-to-record river flooding will continue across
portions of central Florida, with considerable flooding in northern
Florida. Considerable flash and urban flooding is expected across
coastal portions of northeast Florida through Friday. Local
significant flooding in southeastern Georgia and eastern South
Carolina is expected through the end of the week.
