Keys points about Ian from the state Climate Office

• The track forecast for Ian has shifted to the east, and more eastward shifts are possible, meaning Ian could pass over the Atlantic for a time, allowing it to regain strength before reaching South Carolina. The intensity and extent of all impacts (rain, winds, tornadoes, and surge) depend on Ian’s track.
• A tropical storm watch and storm surge watch are now in effect for the South Carolina coast south from the mouth of the South Santee River.
• Wind Impacts: Breezy conditions will begin well ahead of Ian on Thursday, thanks to the pressure difference between the high pressure to our north and Ian. Gusts to 40 mph are possible.
• Rain Impacts: Rain will start along our coastal areas Friday morning and spread northwestward throughout the day and night. Widespread rainfall totals of 3 to 6″ inland and 6-10 inches along most of the coast are likely, with locally higher amounts in all areas. Flooding is possible.
• Coastal Impacts: Flooding and storm surge will be significant along our coast. Major coastal flooding will likely occur with each high tide Thursday through Saturday.
• Tornado Impacts: Isolated tornadoes will likely occur across the Midlands and Coastal Plain during Ian’s passage through the state.

The forecast track for Ian has shifted to the east since yesterday, which increased the potential impacts of Ian on South Carolina. Ian became a Category 3 hurricane before reaching Cuba early this morning. It is moving over the southeastern Gulf of Mexico this morning.
