Record rainfall set in areas of Hatteras on Memorial Day
By IRENE NOLAN
plume of tropical moisture along with the remnants of Post-Tropical
Cyclone Bonnie teamed up to bring record rainfall to areas of Hatteras
Island on Memorial Day.
According to the National Weather Service in Newport/Morehead
City, widespread 4- to 5-inch rainfall totals were measured on
Hatteras with a record 7.09 inches for May 30 recorded at Billy
Mitchell Airport in Frisco. The previous record was 3.44 inches,
set in 1940.
A monthly rainfall record for the month of May at Billy Mitchell also
fell yesterday. Through Monday, May 30, 12.24 inches of rain had been

-- on Sunday morning and has just been meandering around the coast of
the Carolinas ever since. At mid-day on Tuesday -- two days later
-- the remnants of the storm -- now post tropical -- had just moved
across the border into North Carolina and it was spinning around just
off the coast of Cape Fear, south of Wilmington.
Since there is a very weak steering flow, forecasters at the local
Weather Service office say it will be late Thursday before the remnants
of Bonnie finally move off the coast of the Outer Banks.
Meanwhile, we can expect a chance of showers and
thunderstorms each day -- a 60 percent chance today and Wednesday, 40
percent chance on Thursday, and 30 percent chance on Friday.
However, forecasters say the coverage of the rainfall will be not
nearly as widespread as it was on Memorial Day, although some locally
heavy rainfall amounts are possible in persistent downpours.
"We don't see anything like yesterday coming up," said meteorologist Jim Merrell.
Merrell said a narrow plume of tropical moisture set up just east of
the Bahamas and just kept moving northeast toward the Outer Banks all
"That channel of moisture has moved offshore," added forecaster David Glenn.
Both forecasters noted that although the remnants of the tropical
cyclone are now back over water just offshore, no redevelopment is
"It will just be a rainmaker through the week,"
Glenn said, "and then we'll be back to the regular highs and lows and
The post-tropical system will move east of the Outer Banks by Friday,
but a cold front will approach from the west on Saturday and perhaps
stall over the area until another front pushes through on Monday,
followed by a chance for some drying.
Currently, chances of showers over the upcoming weekend are running 30 to 40 percent.
