The monsoon trough passes through the coastal plains of Guinea
along 10N, 08N22W. The ITCZ continues from 08N22W, 06N33W 06N40W
05N49W. Precipitation: widely scattered moderate to isolated
strong is from 02N to 10N from 21W eastward. Isolated moderate to
locally strong is elsewhere from 15N southward from 60W eastward.
GULF OF MEXICO...
Please, read the Special Features section, for details about
Tropical Storm Arlene.
Moderate to locally fresh winds are from the Yucatan Peninsula
westward. Gentle to moderate winds are elsewhere from 90W
westward. Light to gentle winds are in the SE Gulf. The sea
heights range from 2 feet to 3 feet from 90W westward, and they
range from 1 foot to 2 feet, elsewhere from 90W eastward, away
from Tropical Storm Arlene.
Some smoke and haze, and possible reductions to visibility, are
in the southern parts of the Gulf of Mexico, from the NE Yucatan
Peninsula southwestward, due to ongoing agricultural fires in
southern Mexico and in northern Central America.
Tropical Depression Two is near 26.7N 86.3W 1002 mb at 11 AM EDT
moving S at 4 kt. Maximum sustained winds are 30 kt with gusts to
40 kt. T.D. Two will move to 25.6N 86.2W this evening, 24.2N 85.8W
Sat morning, become a remnant low and move to 23.2N 84.9W Sat
evening, before dissipating Sun morning. Over the western Gulf,
gentle to moderate winds are expected into early next week, with
occasional fresh pulses along the W coast of Yucatan.
CARIBBEAN SEA...
Mostly fresh SE winds are in the central one-third of the area.
Moderate SE winds are in the eastern one-third of the area.
Gentle to moderate winds are elsewhere. The sea heights range from
4 feet to 5 feet from 73W eastward, and they range from 2 feet to
3 feet elsewhere.
An upper level trough, and a surface trough, are in the NW corner
of the Caribbean Sea. Comparatively drier air in subsidence
accompanies the upper level trough.
Precipitation: scattered moderate to widely scattered strong in
clusters, is covering the areas that are from 11N to Cuba between
between 70W and 82W. This area encompasses Hispaniola, the SE
half of Cuba, Jamaica, and the surrounding waters. Isolated
moderate is from 12N southward from 78W westward. The monsoon
trough extends from La Peninsula de la Guajira of northern
Colombia, to 13N80W, through the central sections of Nicaragua,
into the Pacific Ocean.
The 24-hour rainfall totals in inches, for the period that ended
at 02/1200 UTC, are: 1.59 in Montego Bay in Jamaica, 0.30 in
Trinidad, 0.07 in Guadeloupe, and 0.01 in Kingston in Jamaica,
according to the Pan American Temperature and Precipitation
Tables, MIATPTPAN.
A weak pressure pattern will maintain gentle to moderate trades
across the Caribbean and the tropical N Atlantic through the end
of week, with occasional fresh pulses along the N coast of
Venezuela and Colombia. Winds over the central part of the basin
will diminish early next week.
ATLANTIC OCEAN...
A cold front is passing through 31N30W 27N43W, beyond 31N62W. The
front connects eventually to a 1005 mb low pressure center that
is near 31N67W. A surface trough extends from the 1005 mb low
pressure center, to the NW Bahamas, and to 25N80W off the coast of
SE Florida. Precipitation: broken to overcast multilayered
clouds, and isolated moderate to locally strong, are from 20N
northward from 20W westward. Fresh to strong cyclonic wind flow is

The low-level center is still estimated to be near the southwest side of the main area of deep convection. The initial intensity remains 35 kt based on the earlier Hurricane Hunter data and a Dvorak 2.5 classification from TAFB. The tropical-storm-force winds are confined to a relatively small region of about 60 n mi to the north of the center in the area of strongest thunderstorms. Arlene is currently moving to the south-southeast at about 5 kt and is being steered by a mid- to upper-level trough that it is embedded within. This overall motion is expected to continue during the next day or two. Although Arlene has strengthened a little today, the models are in good agreement that increasing vertical wind shear and notably drier air are expected to affect the cyclone beginning tonight. These conditions should cause a weakening trend, and Arlene is expected to become a remnant low on Saturday and dissipate on Sunday. The main hazard expected from Arlene is the potential for heavy rain over portions of south and central Florida through Saturday.

and the Southwest North Atlantic including the Bahamas
This is the last Marine Weather Discussion issued by the National
Hurricane Center. For marine information, please see the Tropical
Weather Discussion at: hurricanes.gov.
...GULF OF MEXICO...
High pressure along the middle Atlantic coasts extending SW to
the NE Gulf will remain generally stationary throughout the
week. This will support moderate to fresh E to SE winds over the
basin through Tue. Winds will increase to fresh to strong late
Tue through Fri as low pressure deepens across the Southern
Plains.
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...
A ridge NE of the Caribbean Sea will shift eastward and weaken,
diminishing winds and seas modestly through Wed. Trade winds
will increase basin wide Wed night through Fri night as high
pressure builds across the western Atlantic.
...SW N ATLANTIC INCLUDING THE BAHAMAS...
A weakening frontal boundary from 25N65W to the central Bahamas
will drift SE and dissipate through late Tue. Its remnants will
drift N along 23N-24N. The pressure gradient between high
pressure off of Hatteras and the frontal boundary will support
an area of fresh to strong easterly winds N of 23N and W of 68W
with seas to 11 ft E of the Bahamas late Tue through Fri.

Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EST Thu Dec 1 2022
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Tropical cyclone activity in the Atlantic basin during November was
above average in terms of the number of named storms and
hurricanes. Two hurricanes (Martin and Nicole) formed in the basin
during November, and Lisa which developed in late October became a
hurricane early in November. Based on a 30-year climatology
(1991-2020), a tropical storm forms in November every one or two
years. Although Martin did not affect land as a tropical cyclone,
Nicole became a hurricane when it was affecting the northwestern
Bahamas, and it became the first November hurricane to make landfall
in Florida since Kate in 1985. Lisa also made landfall in Belize
as a hurricane during the month of November.
Overall, the 2022 Atlantic hurricane season featured near normal
activity in terms of the number of named storms and hurricanes, but
was slightly below average in terms of the number of major
hurricanes. In 2022, fourteen named storms formed, of which eight
became hurricanes, and two became major hurricanes - category 3 or
higher on the Saffir-Simpson Hurricane Wind Scale. This compares to
the long-term (1991-2020) averages of 14 named storms, 7 hurricanes,
and 3 major hurricanes. In terms of Accumulated Cyclone Energy
(ACE), which measures the strength and duration of tropical storms
and hurricanes, activity in the basin in 2022 was slightly
below average. The ACE for 2022 is 80 percent of the long-term
(1991-2020) mean.
Reports on individual cyclones, when completed, are available at
