As
the
storm

entered
Arriving
a
region
of
higher
wind

it
began

,
and
was
subsequently
downgraded

to
a

.
After

,
Susan
started
Process_start
to
accelerate
Cause_change_of_strength
towards
the
southeast
and
while
starting

to
weaken
significantly
passed
Motion_directional
close
enough
to
Fiji
during
January

to
cause

gale-force
winds
in
Fiji
's
southern

western
islands
.
over
the
next
few
days
the
system
started
Process_start
to
weaken
Cause_change_of_strength
as
it
passed
Motion_directional
through
the
french
polynesian

islands
,
and
became

.
During
December
15
,
the
system
maintained
Preserving
its
peak
intensity
,
as
it
moved
Motion
through
the
uninhabited
Acteon
Group
of
islands
,
before
during
the
next
day
it
started
Process_start
to
gradually
weaken
Cause_change_of_strength
.
Late
on
August
11
,
Hurricane
Catastrophe
Ismael
began
Process_start
to
weaken
Cause_change_of_strength
as
it
encountered
Hostile_encounter
cooler
waters
.
thereafter
,
gladys
began
Process_start
to
weaken
Cause_change_of_strength
and
passed
Motion_directional
very
close
to
cape

Competition
,
newfoundland
before
merging
Cause_to_amalgamate
with
a
large
extratropical

the
next
day
.
However
,
it
began
Process_start
to
weaken
Cause_change_of_position_on_a_scale
again
while
approaching
Arriving
the
Gulf

of
the
United

.
Fern
continued
to
weaken

to
a

on

.

to

It
began

over
the

.
Continuing
to

Once
over
the

,
the
storm
made history
Creating
when
it
was
the

;
dry

was
spread

throughout
the
storm

in
an
unsuccessful
effort
to
weaken

the
hurricane
,
though
changes

in
the
track
were
initially
blamed

.
Once
inland
,
the
system
continued
to
weaken
Cause_change_of_position_on_a_scale
,
degenerating
Change
to
tropical
depression
strength
before
transitioning
Cause_change_of_position_on_a_scale
into
an
extratropical
storm
later
that
day
.
Increasing
Cause_change_of_position_on_a_scale
wind
shear
and
an
acceleration
Cause_change_of_position_on_a_scale
in
forward
speed
caused
Causation
Gwenda
to
quickly
weaken
.
Once
over
land
,
the
system
began
Process_start
to
quickly
weaken
Cause_change_of_position_on_a_scale
,
and
dissipated
Change
near
the
Rio
Grande
on
July
22
.
During
November
18
,
due
to
cooler
waters
and
increased
Cause_change_of_position_on_a_scale
wind
shear
,
Tia
started
Process_start
to
weaken
Cause_change_of_strength
as
it
moved
Motion
southwards
under
the
influence
of
a
strengthening
upper-level
northerly
wind
flow
.
After
peak
Cause_change_of_position_on_a_scale
intensity
on
September
28
,
unfavorable
conditions
caused
Causation
Joyce
to
become
Becoming
disorganized
and
weaken
Cause_change_of_position_on_a_scale
.
In
contrast
with
predictions
,
Joyce
continued
to
weaken
Cause_change_of_position_on_a_scale
and
became
Becoming
a
tropical
depression
on
October
1
while
crossing
Motion_directional
through
the
southern
Windward
Islands
.
After
passing
Motion_directional
near
Réunion
,
it
began
Process_start
to
weaken
.
The
hurricane
Catastrophe
quickly
strengthened
Cause_change_of_strength
to
become
Becoming
the
only
major
hurricane
Catastrophe
of
the
season
,
reaching
Arriving
maximum
sustained
winds
of
125
mph
(
205
km/h
)
on
September
8
;
after
maintaining
Preserving
its
peak
strength
Cause_change_of_strength
for
24
hours
,
Erika
began
Process_start
to
weaken
Cause_change_of_position_on_a_scale
as
it
passed
Motion_directional
over
cooler
waters
.
Afterwards
,
the
hurricane
Catastrophe
began
Process_start
to
accelerate
Cause_change_of_position_on_a_scale
northeastwards
and
weaken
Cause_change_of_strength
.
Increased
wind
shear
caused
Causation
the
cyclone
Catastrophe
to
rapidly
weaken
Cause_change_of_strength
,
and
both
BoM
and
JTWC
discontinued

on
Gillian
on
26
March
.
By
January
1
,
2002
,
the
cyclone
began
Process_start
to
weaken
as
it
underwent
an
extratropical
transition
.
After
attaining
peak
intensity
on
July
27
,
Gil
encountered
Hostile_encounter
cooler
sea
surface
temperatures
and
began
Process_start
to
weaken
Cause_change_of_strength
.
Subsequently
,
Gil
began
Process_start
to
weaken
Cause_change_of_strength
once
again
as
it
threatened
Warning
the
Northwestern
Hawaiian
Islands
.
However
,
southwesterly
upper-level
winds
caused
Causation
Gordon
to
weaken
as
it
approached
Arriving
land
,
and
it
was
downgraded
Cause_change_of_position_on_a_scale
to
a
tropical
storm
Catastrophe
by
late
on
September
17
.
Afterwards
,
Osea
began
Process_start
to
weaken
Cause_change_of_strength
because
of
increased
wind
shear
,
and
the
cyclone
Catastrophe
started
Process_start
moving
Motion
southeast
.
After
slight
oscillations
in
strength
,
an
upper-level
trough
forced

Catastrophe
northwest
on
July
21
,
and
Emilia
began
Process_start
to
weaken
Cause_change_of_strength
thereafter
.
However
,
on
the
following
Self_motion
day
,
wind
shear
increased
Cause_change_of_position_on_a_scale
again
,
while
sea
surface
temperatures
decreased
Cause_change_of_position_on_a_scale
,
causing
Causation
Jose
to
weaken
Cause_change_of_strength
and
quickly
transition
into
an
extratropical
cyclone
.
However
,
at
the
same
time
the
cyclone
also
entered
Arriving
an
area
with
strong
wind
shear
and
thus
began
Process_start
to
weaken
Cause_change_of_strength
.
over
the
ensuing
two
days
saomai
would
weaken
Cause_change_of_strength
slightly
before
making
landfall
on
okinawa
island
.
After
attaining
maximum
sustained
winds
of
45
mph
(
75
km/h
)
,
the
storm
began
Process_start
to
weaken
from
an
interaction
with
the
high
terrain
of
Hispaniola
.
However
,
increased
Cause_change_of_position_on_a_scale
wind
shear
caused
Causation
the
storm
Catastrophe
to
weaken
Cause_change_of_strength
to
a
tropical
depression
before
making
landfall
near
Melbourne
,
Florida
,
the
next
morning
.
However
,
increased
Cause_change_of_position_on_a_scale
vertical
wind
shear
caused
Causation
it
to
weaken

day
and

at
noon
on
August

,
and
stronger

Once
inland
,
the

continued
to

while
crossing

Florida
,
and
dissipated
Dispersal
shortly
after
emerging
Coming_to_be

.
Thereafter
,
the
hurricane
Catastrophe
began
Process_start
to
weaken
Cause_change_of_strength
while
moving

across
Florida
,
falling
Cause_change_of_position_on_a_scale
to
Category

intensity
only
several
hours
after
landfall
late
on

.
The
system
continued
to
weaken
Cause_change_of_strength
and
transitioned
Change
into
an
extratropical
cyclone
near
the
border
of
North
Carolina
and

early
on
September
18
.
Once
inland
,
Sam
was
slow
to
weaken
Cause_change_of_strength
as
it
re-curved
Motion
eastward
,
and
persisted
for
nearly
a
week
inland
before
dissipating
Dispersal
on
14
December
.
Later
on
December
20
,
wind
shear
in
the
region
increased
Cause_change_of_position_on_a_scale
,
causing
the
system
to
weaken
.
After
reaching
the
Atlantic
on
the
following
day
,
the
storm
began
Process_start
to
weaken
.
The
tropical
cyclone
reached
Arriving
its
peak
intensity
with
winds
of
105
mph
(
165
km/h
)
two
days
later
;
however
,
Hurricane
Odile
began
Process_start
to
weaken
Cause_change_of_strength
as

it
encountered

and
was
downgraded
Cause_change_of_position_on_a_scale
to
a

Catastrophe
shortly
before
making
Causation
landfall
northwest
of
Zihuatanejo
.
An
approaching
Arriving
trough
over
the
central
United
States
induced
Causation
high
wind
shear
over
Sandy
as
it
traversed
Motion_directional
the
Bahamas
,
causing
Causation
the
hurricane
to
weaken
Cause_change_of_strength
to
a
tropical

while
turning
Becoming
more
northeastward
.
Shortly
after
,

to
weaken
.
After
turning
Change
northward
in
response
Response
to
a
weakening
Cause_change_of_strength
subtropical
ridge
,
the
typhoon
underwent
a
series
of
eyewall
replacement
cycles
that
caused
Causation
it
to
weaken
Cause_change_of_strength
.
It
maintained
its
peak
strength
for
a
day
;
shortly
thereafter
,
the
system
began
Process_start
to
weaken
Cause_change_of_strength
.
The
hurricane
moved
Motion
westward
due
to
a

ridge
while
undergoing
two
eyewall

cycles
:
the
first
was
around

and
was
completed
when

was
a

shortly
after
