Hurricane GingerBy Wikipedia
Hurricane Ginger was a hurricane during
the 1971
Atlantic hurricane season. It is a classic example of a subtropical
wanderer; that is, a tropical storm in the subtropics with weak steering
currents. Hurricane Kyle in 2002 is another example of one. The
hurricane's 29 days as a tropical cyclone makes Ginger the longest-lived
Atlantic system.
Origins and the first week
In early September of 1971, a series of upper level lows existed in the
western Atlantic. A trough of low pressure existed across the Gulf of
Mexico through the Bahamas, and various tropical systems formed from this,
including Fern, Heidi, 2 tropical depressions, and eventually Ginger. As
one upper level low sat over the Gulf Stream, it extended towards the
surface and became tropical. On September 5, a tropical depression formed
while located about 350 miles east of Nassau, Bahamas. For the next four
days, it drifted to the east without strengthening. Gradually it got
better organized, and on September 10, the storm was named Ginger. As it
picked up forward momentum, so did its winds. On September 11 Ginger
became a hurricane while located 315 miles south-southeast of Bermuda.
Stalling and the second week
Ginger reached her peak on September 14 of 105 M.P.H. winds, but
weakened soon after. A building high pressure system to the northeast
forced the system to the southwest. Steering currents were weak in the
area, resulting in a drifting Ginger to the west. From the 19th to the
20th, Ginger executed a small loop while located 750 miles east of
Bermuda. During this time, upwelling lowered the winds to minimal
hurricane strength, but it remained a hurricane.
Moving westward and the third week
After looping, Ginger appeared to pose a threat to Bermuda, but it
passed 100 miles to the south on the 23rd. The next day, it again began
drifting to the southwest, where it moved a little over 200 miles over
four days. During this time, Reconnaissance aircraft continually reported
winds of hurricane strength, as well as a large eye, at times up to 80
miles wide.
Landfall, loss of tropical characteristics, and the fourth week
As it moved northwestward towards North Carolina, it gradually
re-strengthened. On the 29th it reached its second peak, this time of 100
M.P.H. winds, but steadily weakened prior to landfall. On September 30,
Ginger hit Morehead City, North Carolina as a minimal hurricane. It
brought heavy rains to North Carolina, causing $10,000,000 in damage, but
no deaths. As it moved inland, it continued to lose strength, and on
October 3, while located near Williamsburg, Virginia, Ginger lost her
tropical characteristics. The extratropical low moved off the coast,
finally dissipating on October 5.
Records
- Tropical Cyclone Longevity: Ginger was a tropical cyclone from
September 4th to October 3rd, a total of 29 days. This record has been
unsurpassed in the Atlantic Ocean, though Hurricane John in the 1994
Pacific hurricane season lasted a little longer.
- Hurricane Longevity: Ginger was a hurricane from September 11th to
September 30th, a total of 20 days. This is one of the longest for a
hurricane.
- Number of tropical cyclones on a single day: On September 11th,
there were 5 active tropical cyclones at once; Tropical Storm Edith
(later a hurricane to hit Louisiana), Tropical Storm Fern (over
southeast Texas), Hurricane Ginger, Tropical Storm Heidi, and a
tropical depression that would later become Hurricane Janice.)
