Tropical Storm Debby slogs through North Carolina. Heavy rain is still a big threat.

Tropical Storm Debby made its second landfall Thursday morning, moving into South Carolina and beginning its still-slow trek into North Carolina.

Once inland, the storm picked up some speed as predicted. At 8 a.m., it was about 65 miles north-northwest of Myrtle Beach and moving to the north-northwest at about 7 mph, the National Hurricane Center said.

There is widespread risk of flash flooding, and some tornadoes are possible.

How much more rain can Debby bring?

The storm is expected to drop an additional 3 to 6 inches of rain across southeastern North Carolina through Friday, with locally higher amounts, forecasters say, bringing rainfall totals as high as 15 inches in some places.

The bulk of the remaining rainfall will come Thursday, forecasters say.

How strong are Debby’s winds?

The storm had maximum sustained winds of about 45 mph Thursday morning, with higher gusts.

The storm is expected to weaken some through the day Thursday, while also picking up forward speed.

By Friday, Debby should be downgraded to a tropical depression, forecasters say.

Since Debby’s rains have saturated the ground in most places, trees are likely to fall and some will take power lines with them.

Duke Energy reported more than 100,000 customers without power from Charlotte to the coast as of Thursday morning.

When will the storm be gone?

The center of Tropical Storm Debby is expected to pass through the middle of North Carolina Thursday and Thursday night. The center of the storm is expected to move into Virginia early Friday morning.

Central North Carolina will continue to see some effects of the storm Friday, with some showers and breezy conditions with wind gusts up to 21 mph.

Rainfall totals on Friday should be less than a half-inch expected in areas of strong thunderstorms.

Sunny skies should return on Saturday.
