Hurricane Ian Back to Category 1: Warning And Storm Surge Focus For South Carolina

Warnings

Thursday Evening September 29, 2022

At 5 PM Ian is a hurricane again with winds of 75 mph. It is over the very warm water of the Gulf Stream.  It is NOT going to be anything like what hit Florida, but it will be a formidable event as an expected Category 1.

So far Ian has been challenging because it veered to the RIGHT side of the forecast cone with less of a slow down. That allowed it to cross Florida faster, which in turn allowed it more space and tie over into the Atlantic to intensify again. 

A Hurricane Warning has been issued for ALL of the South Carolina Coast. I would like to once again examine the strong vs. weak side of the storm. This, plus the shape of the coastline, will help show which areas will get hit hardest, while others will avoid the worst.

Wind And Storm Surge Focus

The most destructive part of a landfalling hurricane is the storm surge. We just saw that in Florida (and I have included two videos on the pop out box here on this page).  

Here is a look at the forecast and IF landfall is around Charleston SC, who may get the strongest, or weaker part of the storm.

Hurricane Ian Wind Forecast Thursday September 29

Snapshot at 2 PM Friday

I want to show this wider view to show the immediate impact of the wind and storm surge.

Farther up the coast, there will be brisk winds to Ocean City in Maryland, but more like a Nor’easter there. I will have a focus on the Mid Atlantic shortly.

Let’s take a closer look at South Carolina below.

 

Reminder About The Storm Structure:

The right side is stronger due to winds moving onshore FROM the ocean or Onshore with the forward movement of the storm. 

The left side is weaker with winds FROM the land or Offshore and opposite the forward movement of the storm. 

Coastline Winds/Waves: 

South Carolina Close Up

Considering the potential landfall on or near Charleston, SC… The stronger impact will be to the north on that RIGHT SIDE with the Onshore Wind! This will include Awendaw and Georgetown.

However to south or LEFT, Hilton Head and Savannah will get much less storm surge with the wind blowing Offshore.
