Hurricane Ian Advisory #4 – September 28, 2022

Hurricane Ian Advisory #4
September 28, 2022 – 6:00 pm

Hurricane Ian made landfall along the Florida Gulf Coast on the afternoon of Wednesday, September 28, 2022, as a strong Category 4 hurricane with maximum sustained winds of 150 mph. Hurricane Ian is now moving northeast across the state of Florida and is expected to emerge into the Atlantic Ocean on Thursday.

There is still uncertainty with the track and intensity of the storm after it emerges from the east coast of Florida. Because Ian is now forecast to be over the Atlantic Ocean for a longer period of time, there is an increased possibility of hurricane force winds in our area.

Earlier today, the National Weather Service (NWS) issued a Hurricane Watch for coastal counties, including Charleston County. The area also remains under a Tropical Storm Warning and Storm Surge Warning.

According to NWS Charleston, there is high confidence that Hurricane Ian will impact our area. Below is a summary of today’s report from NWS Charleston:

  • Minor to moderate wind damage is possible. Tropical storm force winds (39-73 mph) are expected along the South Carolina coast starting on Thursday and continuing into Friday. The best chance for tropical storm force winds, and possibly low-end hurricane force wind gusts (74+ mph), will be along the immediate coast and within any rain bands. Scattered power outages due to downed trees and limbs are a possibility.
  • Moderate coastal flooding is expected Thursday through Saturday, especially during times of high tide. The highest threat for coastal flooding is expected Friday and Friday night. A storm surge of 4-5 feet is possible along the South Carolina coast.
  • Moderate to high threat for flooding rainfall on Friday and early Saturday, especially during times of high tide. A total of 6-8 inches of rain is possible along the coast, with locally higher amounts.
  • Isolated tornadoes are possible, mainly within stronger rain bands between Thursday and Friday nights. The highest threat for tornadoes will be in the coastal areas, especially from Savannah northward.
  • Life-threatening marine/surf conditions will exist Wednesday night through early Saturday, with the worst conditions expected Friday and Friday night. Moderate to severe beach erosion, high surf conditions and dangerous rip currents are likely.

On Wednesday afternoon, Governor Henry McMaster declared a statewide State of Emergency effective at 3:00 pm on Wednesday, September 28th. The Governor has not issued an evacuation order.

During a press conference on Wednesday afternoon, representatives from the Charleston County Emergency Management Department (CCEMD) encouraged residents in low-lying and flood prone areas to consider relocating during the storm.
