N.C. may see 15 more inches of rain from record storm

The Palm Beach Post - - AFTERMATH OF FLORENCE - By Greg Porter and Ja­son Sa­menow Wash­ing­ton Post

De­spite its weak­ened sta­tus to a trop­i­cal storm, Florence has del­uged parts of the North Carolina coast­line with tor­ren­tial and his­toric amounts of rain. Many ar­eas in south­east­ern North Carolina have en­dured 15 to 30 inches of rain and up to an­other 15 inches could fall.

The rain is re­sult­ing in a cat­a­strophic flood­ing in south­east North Carolina which is spread­ing into the in­te­rior, reach­ing even into the pop­u­la­tion cen­ters of Raleigh and Char­lotte. Al­ready, the event has bro­ken North Carolina’s state record for most rain in a trop­i­cal storm or hur­ri­cane, with a pre­lim­i­nary re­port over 30 inches.

The flood­wa­ters are ex­pected to push many rivers to all-time record high lev­els and, to­ward the moun­tains of western North Carolina and south­west Vir­ginia, may spur life-threat­en­ing land­slides.

The As­so­ci­ated Press re­ports the storm may un­load 18 tril­lion gal­lons of rain on the South­east and Mid-At­lantic. “Florence’s 18 tril­lion gal­lons is as much wa­ter as there is in the en­tire Ch­e­sa­peake Bay,” its ar­ti­cle says. “It’s also enough to cover the en­tire state of Texas with nearly four inches of wa­ter.”

Onslow County, lo­cated about 50 miles to the north­east of Wilmington, has been hit par­tic­u­larly hard. The Na­tional Weather Ser­vice of­fice in New­port, North Carolina, (lo­cated on the eastern edge of Onslow County) recorded a storm to­tal of 23.75 inches just af­ter mid­night.

A cit­i­zen weather ob­server posted a to­tal of 30.58 inches of rain in Swans­boro, which is in Onslow County, and would be a state a record for a trop­i­cal storm or hur­ri­cane if ver­i­fied. While the amount is un­of­fi­cial, it would shat­ter the old record of 24 inches — set near Wilmington dur­ing Hur­ri­cane Floyd in 1999.

Florence is fore­cast to “drop al­most dou­ble” the vol­ume of rain over the state com­pared to Floyd, tweeted Ryan Maue, me­te­o­rol­o­gist for weath­er­mod­els.com.

Since mak­ing land­fall at Wrightsville Beach in North Carolina on Fri­day morn­ing, Florence’s for­ward speed has slowed down dra­mat­i­cally, with the storm’s cen­ter of cir­cu­la­tion only about 100 miles away from Wrightsville Beach a full 24 hours af­ter land­fall. The storm’s slow and par­al­lel move­ment to the coast­line cre­ated sev­eral bands of heavy rain, ca­pa­ble of pro­duc­ing 2 to 4 inches of rain per hour, sit­ting over the same lo­ca­tions for es­sen­tially the last day and a half.

Florence will con­tinue to move very slowly to the south­west on Satur­day, which in turn will drag the axis of heavy rain bands to the south­west as well. That should spell some re­lief for the in­un­dated ar­eas of Onslow County, but un­for­tu­nately puts the city of Wilmington, south­east coastal com­mu­ni­ties of North Carolina and north­east ar­eas of South Carolina in the line of fire in­stead.

Most of the rivers in north­east South Carolina and eastern North Carolina are ex­pe­ri­enc­ing mod­er­ate to ma­jor flood­ing and, in some cases, many con­tinue ris­ing well into next week as flood­wa­ters from the in­te­rior flow down­stream.

The Cape Fear River in Fayet­teville, North Carolina, is fore­cast to rise an as­ton­ish­ing 45 feet by Tues­day.

Flood­ing con­cerns ex­tend be­yond the coast of North Carolina as well. Flash flood­ing has spread into Raleigh and will ex­pand over Char­lotte as well, where flash flood ad­vi­sories are in ef­fect.
