Like Hurricane Harvey, which stalled over Texas in 2017, Florence could linger over the Southeast for several days after landfall.

Florence could bring a life-threatening coastal storm surge, and inland flooding as far north as Virginia, the NHC said.
The US military said it was sending an advance team to Raleigh, North Carolina, to coordinate with federal and state partners. If you're headed to the region, you may be wondering how Hurricane Florence will affect flights.
The wafer-thin, 16-mile long island doesn't have a bridge.
"This latest briefing is part of the president's monitoring of multiple storms that are predicted to affect the U.S.in the coming days", Sanders said in the statement, adding that the White House is in contact with governor's offices in all the areas affected, including the Carolinas. Residents and visitors in popular tourist spots such as Duck and Corolla faced a Tuesday deadline.
Wherever Florence hits, it will nearly certainly disrupt flights - not only at airports along the coast but also inland after the storm moves ashore. "Probably not too much better, but most likely safer than here", she said.
"The evacuation order will be inconvenient, but we do not want to sacrifice one SC life, we are not going to gamble the lives of SC people", McMaster said. The order applies to all eight counties along the coast: Jasper, Beaufort, Colleton, Charleston, Dorchester, Georgetown, Horry and Berkeley counties. For Scotland County Schools, classes will be on a half-day schedule on Wednesday, then closed Thursday and Friday - which means Wednesday's varsity football game, rescheduled from Friday, has now been canceled.
Concerns about the monster storm extended even into Virginia.
I have ordered a full coastal evacuation effective noon tomorrow, Tuesday, September 11. The evacuation zone includes the most flood-prone coastal areas, Northam said. Tuesday morning's forecast still supports this, the National Hurricane Center said.
Florence was producing large swells expected to reach from the northern Caribbean to the southern coasts of Canada's maritime provinces.
"Florence is. expected to remain an extremely risky major hurricane through Thursday", the hurricane center warned. Maximum sustained winds are near 75 miles per hour.
The hurricane is generating swells that are already affecting Bermuda and the U.S. East Coast.
The storm's first effects were already apparent on barrier islands as unsafe rip currents hit beaches and seawater flowed over the road. Obviously it's a big storm with high winds. Forecast models suggest that more than two feet of rain could fall over the higher elevations of the Carolinas and Virginia, which would generate unsafe flooding downstream.
"Prepare NOW to evacuate you and your family", Shepherd tweeted Monday. Evacuation shelter locations will be available on scemd.org and in the SC Emergency Management Division's mobile app as soon as they are opened.
It is then forecast to close in on North or SC on Thursday, hitting a stretch of coastline that is vulnerable to rising sea levels due to climate change.
