A September 7 spaghetti model.

As new forecast models show a shift to the east for Hurricane Irma, the governor of South Carolina has now declared a statement of emergency for that state.

Hurricane Irma is an extremely dangerous storm reaching 185 mph wind speeds and remaining a Category 5. It’s path has been unpredictable for days, although most forecasting models show it tracking toward Florida. The concern for South Carolina is what it does after that point, and the latest modeling shows that the storm could track north and then into the state.

The governor on September 6 declared a state of emergency for South Carolina, saying that the hurricane now “may pose a significant threat to the state.”

“The National Hurricane Center has determined from forecast models that the State of South Carolina may be impacted by Hurricane Irma,” the governor wrote. “I have been advised that Hurricane Irma, and the associated wind, heavy rain, flash flooding, and severe weather, to include tornadoes, may pose a significant threat to the State of South Carolina.”

The governor also ordered that “the South Carolina Emergency Operations Plan be placed into effect.” He also ordered the activation of South Carolina National Guard at the the discretion of officials. Read the governor’s full September 6 statement here:

The threat to South Carolina all depends on which model you use, but some of the latest ones are not good news for the Carolinas. The latest GFS models show Hurricane Irma heading to the east of Florida, rushing up the Eastern Seaboard, perhaps making landfall somewhere in the Carolinas. Read more about those models here. Spaghetti models – which literally look like noodles on a map – are looking ominous for the state, as they also are showing an eastward and northern track for the hurricane, imperiling South Carolina.

Currently, the storm’s path shows it will likely strike southern Florida and the Florida Keys and the National Weather Service reports that there is an increasing chance of this; what it will do after turning northward is not yet entirely clear. The Post Courier reported on September 5, “The storm could possibly cross Florida, reemerge in the Atlantic and head up toward a landfall in the Carolinas. A direct track to South Carolina could not yet be ruled out.”

“Tropical Weather: Impacts associated with Hurricane Irma are expected this weekend into early next week. It is still too early to pin down the magnitude of the impacts as there remains uncertainty with the track the hurricane will take and how strong it will be as it approaches the Southeast United States. Everyone across Southeast South Carolina and Southeast Georgia, especially those in hurricane prone areas, should have a hurricane plan in place and continue to monitor the latest forecasts from the National Hurricane Center.

Rip Currents: Long period swells generated by approaching Hurricane Irma will persist into early next week. These swells will enhance the risk for powerful and dangerous rip currents at area beaches into early next week as Irma draws closer to the region.”Tropical Weather: There is an increasing risk for impacts associated with Hurricane Irma over the weekend into early next week.
