Ian predicted to hit as cat 1 now.  Disco in spoiler - moved more east than expected and faster, thus reached water faster. Winds back up to 70mph.  Calling it a hybrid, winds are atypical structure and well out in front of the storm. Peak surge adjusted up to 7 feet for SC.

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 
advisory.

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
officials.

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.

There you go with logic and reason. Using those usually comes right after you say, "Oops, that was really dumb." (Edit: or right after your wife asks "What were you thinking?!!!") :classic_tongue:

Most don't plan to be directly exposed. They think they are sheltered well enough. It's when their shelter proves inadequate that they win the Darwin award.

I keep forgetting logic and reasoning should be tossed out.  I'm too old school.  😁

Welp, I'm quick to say when I might be wrong, and I might be wrong. This system, over the gulf stream, with some structure still intact and currently a 70mph TS, might be able to hit Cat 2 before running into S. Carolina. 

BTW...did anyone see the nonsense the GFS came up with east of the Yucatan at the end of the 06z run?

Yes, if this verifies, I would be like 

"NOT AGAIN!!!"

  • The title was changed to Ian | 155 mph 936 mb peak (70 mph and 987 mb) | Secondary peak possible

Seeing some more pictures coming out now. Below is a live stream grab from local news near where the causeway was damaged in Sanibel. Looks more like what I was expecting, lot of vegetation bare, roads washed out, etc. Edited to included a street view of the area Best I can tell  looks like a lot of vegetation in middle of the Blvd washed away.

I want to highlight what many of us saw in real-time last night, included in the NHC 11am Discussion.

”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.”

”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.”

Yep, you are right.  I zoomed in on the latest picture today.  Part of the fence is gone too.
