By 5:00 p.m. Friday, Ian was downgraded after making landfall near Georgetown, SC as a category 1 hurricane. The storm continues to churn into North Carolina as a post-tropical cyclone.
So what is a post-tropical cyclone and how dangerous is the storm at this level?
ABC11 Meteorologist Robert Johnson says Ian as a post-tropical cyclone is still just as dangerous as a tropical storm. The only difference is that it has lost its warm core (tropical characteristics in meteorology) and now has a cooler core.
Ian officially going from a hurricane to a post-tropical cyclone makes no impact for central NC. Impacts are all the same.

You may also be wondering about hurricane categories. For example, how intense is a Category 4 or Category 5 hurricane, and what do the different categories mean for people in the storm's path?
The National Weather Service uses the Saffir-Simpson Scale, which only measures a hurricane's sustained wind speeds using a 1 to 5 rating system. This scale provides estimates of potential property damage, according to NWS.
Category 1 hurricane: A Category 1 hurricane has sustained winds between 74-95 mph, according to NWS.
Category 2 hurricane: Winds on a Category 2 hurricane are between 96-110 mph. According to the NWS, its "extremely dangerous winds" can cause major roof and siding damage to well-constructed homes.
Category 3 hurricane: A Category 3 hurricane has continuous winds between 111-129 mph, where "devastating damage will occur," the NWS said.
Category 4 hurricane: Category 4 storms can cause "catastrophic damage" with their 130-156 mph winds. A Category 4 storm can cause severe damage to well-constructed homes, including damaging most of the roof and exterior walls.
Category 5 hurricane: Category 5 hurricanes are the most devastating, with sustained winds of at least 157 mph.
