iStock/Thinkstock(NEW BERN, N.C.) — Florence weakened to a tropical depression early Sunday, but that was cold comfort to residents in North Carolina who have seen over 2 feet of rain and are now battling major-river flooding and possible tornadoes.Adding to the rain and threat of further flooding, a tornado watch is in effect until at least 5:30 p.m. Sunday for the areas of Wilmington, Fayetteville, Myrtle Beach, Jacksonville, Oak Island and Florence.“It’s bad right now, and we do expect it to get worse over the coming days,” Michael Sprayberry, director of North Carolina Emergency Management, said on ABC’s This Week Sunday. “We know that’s going to be a major mission going forward, because this is historic and unprecedented flooding.”New evacuation orders were issued Sunday morning for a mile-long area along the Cape Fear and Little rivers in North Carolina.Since the storm made landfall in North Carolina on Friday morning as a hurricane, it has been blamed for 14 deaths. Hundreds of water rescues have been carried out by local authorities, Cajun Navy volunteers and the U.S. Coast Guard since Friday morning.The Coast Guard alone has rescued 57 people and eight pets in North Carolina since Florence made landfall, said Coast Guard Adm. Karl Schultz.More than 770,000 customers were still without power as of Saturday night.Major-river flooding a threatCatastrophic flooding unfolded Sunday morning in parts of North Carolina, exceeding flooding 19 years ago in Hurricane Floyd, the National Weather Service said.One waterway — the Cape Fear River — rose 15 feet in just 24 hours from early Saturday to early Sunday. It reached flood stage in Fayetteville, North Carolina, where mandatory evacuation orders were issued Saturday.“This will be very dangerous flooding over the next few days,” the National Weather Service said in a tweet Sunday morning.The Coast Guard head echoed this view.“My biggest concern is the rising water,” Schultz said on This Week, noting that Wilmington, North Carolina, got 24 inches of rain and could potentially get 15 inches more.“We’re looking at a high-water situation,” he said. “The rivers could potentially crest here into the early part of this week. So we have not seen the worst of the flooding.”Schultz was among the emergency officials who briefed President Trump on the storm on Saturday.“We talked about the massive risk the storm poses — catastrophic flooding, prolonged flooding,” he said of the briefing. “We gave him an update on response capabilities in the theater, and the president is completely leaning in — anything the feds need to do to support the local, the state partners here in South Carolina and North Carolina. We feel fully supported.”The Lumber River, near Lumberton, North Carolina, will rise into major flood stage Sunday morning. It is expected to reach a level very near the record Hurricane Matthew set in 2016. Mandatory evacuations were issued for South Lumberton on Saturday.Major-river flooding is also expected on some rivers from southern Virginia to northern South Carolina.The Northeast Cape Fear River, near Chinquapin, North Carolina, will rise above record flood levels set by Hurricane Floyd in 1999. This will cause devastating flooding across much of Onslow County with travel made impossible and many homes completely flooded.The Neuse River — both near Goldsboro and Kinston, North Carolina — will reach major flood stage late Sunday and into Monday. The Waccamaw River, near Conway, South Carolina, will rise near record levels by the end of the week.Florence has dropped a tremendous amount of rain in eastern North Carolina, with a widespread 20 to 30 inches already reported. Radar is estimating that some areas between Wilmington and New Bern, North Carolina, have received over 30 inches of rain.These are some of the latest rainfall totals as of 11 p.m. Saturday:— Swansboro, N.C. — 30.59 inches— Newport/Morehead City, N.C. — 25.20 inches— Elizabethtown, N.C. — 20.17 inches— Jacksonville, N.C. — 16.13 inches— Conway, S.C. — 9.90 inches— Myrtle Beach Airport, S.C. — 6.74 inchesFlorence is now the third storm to set a tropical cyclone state rainfall record in just the last 12 months. Harvey dropped 60.58 inches of rain last year in Texas, setting the state’s new record. Just last month, Lane dropped a maximum of 52.02 inches of rain in Hawaii, breaking the state record. The 30.59 inches that have fallen in Swansboro sets a new record for North Carolina.Florence also currently stands as the sixth-highest tropical cyclone rainfall total across the U.S. for records dating back to 1950.Heavy rain spreads inlandHeavy rains bands are still coming onshore in eastern South Carolina and North Carolina on Sunday morning. Some of the heavier bands have shifted toward Fayetteville, Charlotte and Raleigh.Torrential rain is causing inland flooding with major roadways closed, including large portions of I-95.An additional 6 to 10 inches of rain is still possible along the southeast border of North Carolina and South Carolina.Life-threatening, catastrophic flash flooding is likely over the southern to central Appalachians from western North Carolina into western Virginia and eastern West Virginia. Torrential rain will cause flash flooding and increase the risk for landslides in the higher terrains.Florence is still moving very slowly inland. The track shows Florence moving west through Sunday, and then gradually turning north by Monday. Florence will likely become a remnant low within 36 hours.Even though Florence is weakening, it will still bring significant rainfall inland to the Appalachians before moving toward the Northeast on Tuesday. Totals could exceed 4 inches locally for inland New York and Massachusetts.“People need to heed the warnings from their local emergency management experts and stay in safe ground,” the Coast Guard’s Adm. Schultz said.Copyright © 2018, ABC Radio. All rights reserved.
