As Tropical Storm Debby inches into NC, here’s when the heaviest rain is likely

Update: Tropical Storm Debby made its second landfall Thursday and started a slow slog through North Carolina. Click here for the latest.

Tropical Storm Debby should make its trek through North Carolina on Thursday, bringing heavy rains and potential flooding, forecasters say.

At 11 pm. Wednesday, the storm was about 65 miles south-southwest of Myrtle Beach and moving to the northeast at about 3 mph, about the speed the average healthy adult walks. Debby had maximum sustained winds of around 60 mph with some higher gusts, the National Hurricane Center said.

Forecasters said the storm eventually would pick up some speed for the trip north. It should arrive in North Carolina during the day Thursday, still packing tropical storm-force winds, forecasts say, before being downgraded to a tropical depression as it moves through Virginia.

Tropical Storm Debby could drop another 3 to 9 inches of rain over parts of North Carolina through Friday. That would bring the totals for the week up to 15 inches in some parts of southeastern N.C., the National Hurricane Center said.

A flood watch is in effect in parts of Robeson, Bladen, Columbus, Pender, Brunswick and New Hanover counties through Friday.

A tropical storm warning and storm surge watch are in effect in coastal Brunswick County. And parts of Pender and New Hanover counties are under tropical storm warnings.

Once the storm moves inland again, forecasters expect it to track through the center of the state and head into Virginia. The center of the storm should be out of North Carolina early Friday, but the back side of the storm will continue to produce rain and wind here through Friday night.

Meteorologists said a few tornadoes could occur over parts of eastern North Carolina Wednesday night. The risk of tornadoes will shift northward on Thursday into central North Carolina and central Virginia, the Hurricane Center said.

Where will flooding be the worst?

NC FIMAN — Flood Inundation Mapping and Alert Network — showed six spots in eastern and southeastern N.C. Wednesday where major flooding is expected during or after Debby’s rains, plus more than a dozen sites where moderate or mild flooding is expected. FIMAN uses stream flow data, weather forecasts and other information to identify places where flooding will occur.

As they have been in the past, low-lying areas along the Neuse River are expected to flood in Clayton, Smithfield, Goldsboro and Kinston, along with ones on the Lumber River in Lumberton, the Little River in Spring Lake and the Cape Fear River in Fayetteville and Wilmington.

Most of central North Carolina is under a flood watch through Friday, and flash flooding is expected in low-lying areas and those in urban areas that don’t drain quickly.

Forecasters say Tropical Storm Debby will make its second landfall Wednesday night or Thursday morning and gain some speed for its trek into North Carolina. The storm will continue to bring rain and some wind to the N.C. through Friday night.
