1998 Seasonal Highlights
- It was the deadliest in
over 200 years (11,000 deaths in Central America, Source: Wire
Services)
- A total of 14 tropical
systems (named storms) developed during the 1998 Atlantic Hurricane
Season.
- Mitch was the fourth most
intense hurricane ever observed in the Atlantic basin, and the
strongest ever observed in the month of October.
- In a remarkable span of
35 days, starting on Aug. 19 and ending on Sept. 23, 10 named
tropical cyclones formed. That's about a whole season's worth
of activity crammed into a month. Four of them made landfall
in the United States. In addition, Jeanne and Karl affected the
Cape Verde Islands and Bermuda respectively, while three others
passed near or over the Azores.
- On 25th of September there
were four hurricanes -- Georges, Ivan, Jeanne and Karl -- in
progress at the same time. This is the first time such an event
occurred this century.
Highlights of Individual Storms
Alex
Tropical Storm Alex formed
in the eastern Atlantic south of the Cape Verde Islands on Jul.
27th with wind speeds of 50 mph. The storm diminished Aug d.
several hundred miles northeast of the Leeward Islands.
Bonnie
Tropical storm Bonnie developed
over the tropical Atlantic on August 19th, 675 east of the Leeward.
It moved west-northwest and then north. The storm neared the
coast of North Carolina on Aug. 26th, near Cape Fear and moved
slowly over extreme eastern emerging of f the Outer Banks near
Kitty Hawk early on the 28th. Bonnie weakened quickly. At least
3 deaths are attributed to Bonnie
Charley
Forming as a tropical depression
in the southeastern Gulf of Mexico on August 21st, Charley developed
quickly reaching wind speeds of 60 mph moving at 15 mph toward
the southern Texas coast. The storm later moved inland near Port
Aransas, Texas on Aug 22d. Torrential rain caused floods that
claimed at least 12 lives in Texas, mainly in the Del Rio Area
and 9 more across the border in Ciudad Acuna, Mexico.
Danielle
Danielle formed over the
Central Tropical Atlantic Ocean on August 24 and intensified
into a tropical storm later that same day. It became a Hurricane
on August 25th and moved West-Northwest for 5 days. After passing
a couple of hundred miles northeast of the northwest Bahamas,
Danielle turned to the North on 31 August. By Sept. 1, Danielle
was headed northeastward and out to sea.
Earl
Earl formed in the Gulf
of Mexico about 575 miles south-southwest of New Orleans on August
31. It gradually intensified to Category 2 on the Saffir-Simpson
Hurricane Scale while moving north and northeast. Earl made landfall
as a Category 1 Hurricane near Panama City, Fla., during the
early morning of Sept. 3. Earl produced an estimated storm surge
of 8 feet in Franklin, Wakulla and Taylor counties and about
12 inches of rain in Panama City, Fla.
Frances
Frances formed in the Gulf
of Mexico, about 220 miles southeast of Corpus Christi, Texas,
on Sept. 8 and reached Tropical Storm status the next day. Frances
moved slowly on a general northwesterly track and made landfall
just to the northeast of Port Aransas, Texas as a 65 mph Tropical
Storm. Frances drenched portions of Texas and Louisiana.
Georges
Georges formed in the Far
Eastern Atlantic from a tropical wave early on the 15th of September.
The system was upgraded to a tropical storm on the 16th. By late
afternoon on the 17th, satellite imagery indicated that Georges
developed an eye and was upgraded to Hurricane status. Georges
moved on a general west to west- northwest course at 15 to 20
mph for the next several days. During this period, Georges is
estimated to have reached a peak intensity of 150 mph (Category
4) and a minimum central pressure of 938 mb on the evening of
the 19th, while located about 420 miles east of Guadeloupe in
the Lesser Antilles. Georges first of many landfalls occurred
at Antigua in the Leeward Islands late on Sept. 20th. After moving
near or over other islands of the northeast Caribbean, including
the U.S. Virgin Islands, it then hit Puerto Rico on the evening
of Sept. 21 with estimated maximum winds of 115 mph (Category
3). Georges weakened very little while over Puerto Rico and was
even stronger when it made landfall in the Dominican Republic
on the afternoon of Sept. 22 with estimated maximum winds of
120 mph (Category 3). Georges weakened after crossing the mountainous
terrain of the Hispaniola and made landfall in Eastern Cuba on
Sept. 23rd with estimated maximum winds of 75 mph (Category 1).
Georges continued along
the northern coast of Cuba for most of Sept. 24th. Thereafter,
the Hurricane moved into the Florida Straits early on the 25th
and re-intensified making landfall near Key West, Fla. On the
25th with estimated maximum winds of 105 mph (Category 2). Georges
continued on a general west-northwest to northwest track on the
26th and 27th, turning to a north-northwest heading and gradually
slowing down as it approached the Coast of the Central Gulf of
Mexico. Georges made its final landfall near Biloxi, Miss., as
a Category 2 Hurricane. Then Georges meandered and weakened to
a tropical storm on the afternoon of Sept. 28th. Georges was
downgraded to a tropical depression by mid-morning on Sept. 29th
while located about 35 miles north-northeast of Mobile, Ala.
Hermine
Hermine developed from an
area of low pressure located over the Northwestern Caribbean.
It moved into the Gulf of Mexico and became a tropical depression
on Sept. 17th. The depression meandered over the Central Gulf
for a couple of days and reached Tropical Storm status on the
19th when located about 150 miles south- southwest of New Orleans.
Hermine moved inland near Cocodrie, Louisiana, with 40 to 45
mph winds early on Sept. 20th producing torrential rains.
Ivan
Ivan developed on Sept.
20th from a tropical wave located a few hundred miles to the
Southwest of the Cape Verde Islands. It remained over the Eastern
Atlantic, moving toward the north to northwest for most of its
one-week lifetime. Ivan became a tropical storm early on the
21st. When the shearing decreased on the 23rd, an eye appeared
and Ivan became a Hurricane. Ivan reached its peak intensity
of 90 mph winds late on the 25th.
Jeanne
Jeanne became a tropical
storm not far off the west coast of Africa on the 21st and intensified
to a hurricane the following day. Jeanne was only the third tropical
storm this century to form so far east in the Atlantic. It moved
west-northwestward for a couple of days, reaching a peak intensity
of 105 mph on Sept. 24th, while located about 600 miles west
of the Cape Verde Islands. The Hurricane turned toward the north
over the East-Central Atlantic late on Sept. 26th and eventually
weakened to a Tropical Storm in the vicinity of the Azores.
Karl
Hurricane Karl developed
from a small low pressure area that was tracked from the Coast
of the Carolinas. It became a tropical depression on the 23rd
of Sept. about 200 miles east-northeast of Bermuda. Karl moved
southeastward and then northeastward and became a 105 mph Hurricane
late on the 26th. It continued moving toward the northeast over
cooler waters and became extratropical on Sept. 28th.
Lisa
Lisa moved mostly northward
over the eastern North Atlantic ocean from Oct. 5- 9 and then
became and then became extratropical. Lisa briefly became a minimal
hurricane with 85 mph winds on Oct. 9. The storm did not affect
land.
Mitch
Mitch formed in the southwest
Caribbean sea from a tropical wave about 360 miles south of Kingston,
Jamaica later on Oct. 21. The system initially moved slowly westward
and intensified to a tropical storm. Mitch then moved slowly
northward and then north-northwestward on Oct. 23rd and 24th,
gradually gaining strength. By early on Oct. 24, Mitch became
a hurricane. Later that day, as the Hurricane moved toward the
west, Mitch began to intensify rapidly. In about 24 hours its
central pressure dropped 52 mb to 924 mb by the afternoon of
Oct. 25. Mitch continued to strengthen and central pressure reached
a minimum of 905 mb about 40 miles southeast of Swan Island on
the afternoon of Oct. 26. This pressure is the fourth lowest
ever recorded in an Atlantic hurricane this century, tied with
Hurricane Camille in 1969. This also represents the lowest pressure
ever recorded for an October Hurricane in the Atlantic basin
this century. At its peak intensity, Mitch's maximum one-minute
sustained surface winds were estimated to be 180 mph a
Category 5 hurricane on the Saffir/Simpson Hurricane scale.
After passing over Swan
Island, Mitch began to gradually weaken on Oct. 27, while moving
toward the Bay Islands off the Coast of Honduras. The center
passed very near the Island of Guanaja and wreaked havoc there,
as well as on the neighboring Island of Roatan.
From mid-day Oct. 27 to
early on Oct. 29, the minimum central pressure rose 59 mb. The
center of Hurricane Mitch meandered near the north coast of Honduras,
then moving southward and inland, weakening to a tropical storm
on Oct. 30. Mitch moved slowly over Honduras and Guatemala on
Oct. 30 and 31, while gradually weakening to a tropical depression.
Mitch generated torrential rains over portions of Honduras and
Nicaragua where the associated floods were devastating. Some
heavy rains also occurred in neighboring countries. Mitch weakened
to a depression on Oct. 30 and continued to produce locally heavy
rain over portions of Central America and Southeastern Mexico.
Nicole
Nicole formed as a Tropical
Storm with 40 mph winds on Nov. 23rd 760 miles east of La Palma
in the Canary Islands moving slowly to the west. By Nov. 25th
(5 a.m. 11/25/98) the storm had winds of 70 mph. |
