Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1805 UTC Wed May 29 2024

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through 
1655 UTC.

...TROPICAL WAVES...

A tropical wave has been introduced in the eastern Atlantic along
17W, south of 15N based on satellite imagery and wave diagnostic
guidance. The wave is moving westward at 15 kt. Scattered moderate
convection is observed from 05N to 12N and east of 23W. 

A tropical wave is in the central Atlantic along 34W, south of
11N, moving westward at 15-20 knots. A few showers are noted near
the wave axis.

Another tropical wave is in the central Atlantic along 58W, south
of 13N, moving westward at 15-20 knots. Scattered moderate 
convection is present from 07N to 12N and between 54W and 62W. 

A tropical wave in the western Caribbean along 82W, south of 21N,
moving westward at 10-15 knots. Scattered moderate to isolated
strong convection is occurring in the SW Caribbean, south of 13W.

...MONSOON TROUGH/ITCZ...

The monsoon trough reaches the Atlantic through the coast of
Guinea near 10N14W and continues southwestward to 08N19W. The ITCZ
extends from 08N19W to 04N33W and then from 04N35W to 05N53W.
Please see the Tropical Waves section for information on the
convection near the monsoon trough and ITCZ.

GULF OF MEXICO...

A few showers are noted on satellite imagery in the western Gulf 
of Mexico, mainly off Veracruz and Tamaulipas. The strong 
convection previously in the NW Gulf has mostly dissipated. The 
remainder of the Gulf is under the influence of a subtropical 
ridge positioned a few hundred miles SE of Newfoundland. The weak
pressure gradient sustains moderate to locally fresh SE winds 
between 90W and 95W. Seas in these waters are 3-5 ft. Light to 
gentle winds and slight to moderate seas prevail elsewhere. 

Hazy conditions due to agricultural fires in Mexico and Central 
America persist across most of the western Gulf, including the 
Bay of Campeche. Observation sites along the Bay of Campeche and 
western Gulf continue to report visibilities at 3 nm of less.

For the forecast, weak surface ridging will continue to dominate
across the Gulf through Sun. As a result, winds will pulse 
moderate to fresh during the evenings through the weekend. A weak 
cold front moving across the far NE Gulf will continue to support 
gentle W to NW winds over that region this morning. Otherwise, 
fresh to strong NE to E winds will pulse near the N and W portions
of the Yucatan peninsula during the late afternoons and at night 
through the weekend. Haze west of 89W due to agricultural fires 
over Central America and Mexico will continue for at least the 
next couple of days, impacting visibility at times.

CARIBBEAN SEA...

Please read the Tropical Waves section for details on the tropical
wave in the western Caribbean.

An upper level trough extending into the NW Caribbean Sea continues
to push tropical moisture northward, and along with the tropical 
wave passage, results in scattered showers over portions of the NW
and central Caribbean, affecting eastern Cuba, Jamaica and 
Hispaniola. The environment will remain conducive for showers and 
isolated thunderstorms to affect eastern Cuba, Jamaica and 
Hispaniola during the next several days, especially in the evening
and night hours. Locally heavy rain and gusty winds are possible,
especially in mountainous areas, leading to flash flooding. 
Please refer to your local weather office for more specific 
information.

The pressure gradient between a 1029 mb high pressure system SE of
Newfoundland and lower pressures in the deep tropics support 
fresh to strong easterly trade winds in the south-central 
Caribbean. This was confirmed by a recent scatterometer satellite 
pass. Seas in these waters are 5-8 ft. Moderate to fresh easterly 
breezes and seas of 3-6 ft are occurring in the north-central and 
eastern Caribbean and Gulf of Honduras. Gentle to light and slight
seas are found elsewhere. Hazy conditions continue to affect the 
Gulf of Honduras due to agricultural fires in Central America. 
Visibilities may decrease below 3 nm at times, especially along 
the northern coast of Honduras and the Bay Islands. 

For the forecast, a moderate pressure gradient between high 
pressure and associated ridging north of the area and low pressure
along near Colombia will force fresh to locally strong trades 
over the S central Caribbean and Gulf of Honduras through today. 
Winds will become moderate to fresh from Thu through the weekend. 
A tropical wave currently over the western Caribbean is causing 
scattered showers and thunderstorms over the SW Caribbean. The 
wave is forecast to move across Central America into the E Pacific
waters tonight into Thu. Smoke from agricultural fires over 
Central America is causing reduced visibilities over the Gulf of 
Honduras.


ATLANTIC OCEAN...

Please read the Tropical Waves section for details on the three
tropical waves in the central and eastern Atlantic.

A late-season cold front has emerged off the southeast coast of 
the United States, extending from 31N78W to Daytona Beach, 
Florida, based on the 1500 UTC surface map. Divergence aloft is 
helping to induce a few showers ahead of the boundary, especially 
north of 26N and west of 70W. Farther east, a cold front enters 
the tropical Atlantic near 31N41W and continues southwestward to 
30N48W, where it becomes a surface trough, stretching
southwestward to near Puerto Rico. The trough is producing 
scattered showers from 20N to 26N and between 50W and 65W. 
Moderate to fresh easterly winds and seas of 4-7 ft are present 
north of these boundaries and east of 57W. The remainder of the 
SW North Atlantic is under the influence of a broad subtropical 
ridge centered SE of Newfoundland, resulting in moderate or 
weaker winds and slight to moderate seas.

The rest of the central and eastern Atlantic is dominated by broad
ridging. The pressure gradient between the broad ridge and lower
pressures in the deep tropics sustain moderate to locally fresh
easterly winds south of a line from the the western Canary 
Islands to the northern Leeward Islands. Seas in these waters are
4-7 ft. Elsewhere, moderate or weaker winds and moderate seas
prevail.

For the forecast W of 55W, surface ridging extending from high
pressure over the NW Atlantic is contributing towards moderate or
lighter winds across the region. A weak cold front is slowly 
emerging from the SE United States with scattered showers and 
thunderstorms associated with it. The front will move eastward 
toward the Greater Antilles later this week and into the weekend, 
bringing moderate to fresh winds. Otherwise, winds and seas away 
from the thunderstorms should remain quiescent for the next few 
days across the forecast waters.

..TROPICAL OUTLOOK MAY 28, 2024..

 


There are three tropical waves being monitored in the Atlantic and the Caribbean. The wave closer to the African coast and the Cabo Verde Islands is the strongest of the three. It is unusual to see strong waves off the African coast this early. A precursor of what's to come this season.  Be Storm Ready!

This is a low-latitude wave, so the southern axis of the wave is being fed by the African monsoon moisture in the area.

Upper-level winds to the north of this wave are not favorable for tropical cyclone formation at this time.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1205 UTC Tue May 28 2024

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 
1050 UTC.

...TROPICAL WAVES...

A tropical wave is E of the Cape Verde Islands from 01N to 14N
with axis near 21W, moving westward at 15 to 20 knots. Scattered
moderate convection is from 01N to 09N between 20W and 30W. 

A tropical wave is in the central Atlantic from 01N to 08N with
axis near 49W, moving westward at about 15 knots. Scattered
moderate convection is from 00N to 08N between 48W and 58W. 

A tropical wave is in the central Caribbean S of 21N with axis
near 74W, moving westward at 10 to 15 knots. Scattered showers are
across Hispaniola and adjacent waters, including the Windward
Passage.  

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal plains of Senegal
close to 15N17W to 07N20W to 05N30W. The ITCZ continues from 
05N30W to 05N40W. For information regarding convection, see the
Tropical Waves Section. 

GULF OF MEXICO...

A weak surface ridge dominates the eastern half of the basin while
lower pressures are ongoing W of 90W. This pressure difference
supports gentle to moderate SE winds W of 88W and light to gentle
variable winds elsewhere. Seas across the region are slight to
moderate with the highest seas to 4 ft happening W of 90W. Haze
continues west of 87W due to agricultural fires over Central 
America and Mexico, whis is limiting visibilities to 3 NM or less. 

For the forecast, weak surface ridging will continue to dominate 
across the Gulf through Sat. As a result, winds will be SE gentle 
to moderate west of 87W through Thu, but become moderate to fresh 
Thu evening through Sat night. A weak cold front will move across 
the far NE Gulf today, followed by gentle W to NW winds. Otherwise,
fresh to strong NE to E winds will pulse near the N and W portions
of the Yucatan peninsula during the late afternoons and at night 
for the next several days. Haze west of 87W due to agricultural 
fires over Central America and Mexico will continue for at least 
the next couple of days. Visibilities will be 3 NM or less in the 
SW Gulf of Mexico. 

CARIBBEAN SEA...

High pressure N of the area and the passage of a tropical wave
across the central basin is supporting fresh to locally strong 
trade winds over the south-central Caribbean and moderate to 
fresh trades elsewhere. Seas basin-wide are slight to moderate,
being highest over the central region with seas to 7 ft.
Otherwise, smoke from agricultural fires over Central America is 
causing reduced visibilities over the Gulf of Honduras.

For the forecast, a moderate pressure gradient between the 
Bermuda High north of the area and lower pressure along N South 
America will force fresh to strong trades over the S central 
Caribbean and Gulf of Honduras through Wed before diminishing late
in the week. A tropical wave currently over the central Caribbean
is causing scattered showers and thunderstorms as it moves slowly
westward during the next couple of days. 

ATLANTIC OCEAN...

A 1021 mb Bermuda High is contributing toward moderate or lighter
winds across the basin, except for moderate to fresh SW winds 
across the offshore zones N of Freeport. The Azores High
associated ridge influences the remainder Atlantic subtropical
waters, thus supporting gentle to moderate winds, except E of 34W,
where winds are moderate to fresh from the NE to E. Moderate to
fresh trades are across the tropical waters from the coast of W
Africa and the Lesser Antilles. 

For the forecast W of 55W, moderate to fresh SW winds will
continue across the offshore zones N and NE of Freeport ahead of 
a weak cold front forecast to emerge from the SE United States 
coast this morning. The front will become stationary north of the 
Bahamas today and dissipate tonight. Scattered showers and 
thunderstorms will accompany the front. Winds and seas away from 
the thunderstorms should remain quiescent for the next few days 
across the forecast waters. Looking ahead, a late-season cold 
front is anticipated to impact the waters north of the Greater 
Antilles Fri night into at least Sat night.

EURO still not excited about developing anything in the Caribbean. 

The Canadian model does show development in the Caribbean tracking over Jamaica and Cuba .

The GEFS ensemble models show some activity in the 
Caribbean but nothing significant at this model run.

Winds still coming out of the west as the transition from El Nino to 
La Nina has not yet occurred. Upper Level winds remain unfavorable for now.




Water Temps across the tropical Atlantic, Caribbean and the Gulf of Mexico 
are nice and warm for tropical cyclone formation.

..TROPICAL OUTLOOK MAY 26, 2024..

 


A tropical wave moving through the eastern Caribbean is accompanied by heavy rains and storms. These storms are moving through the lesser Antilles and the Leeward Islands and will be moving over Puerto Rico. Gusty winds in squalls, heavy rains that can produce flooding, and deadly mud slides could occur if these storms hold together.

Upper-level winds remain unfavorable for development in the Caribbean at this time; however, the ensembles continue to suggest development in the Caribbean in June, so I will continue to monitor this wave as it tracks further west.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1805 UTC Sun May 26 2024

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through 
1635 UTC.

...TROPICAL WAVES...

A tropical wave has been introduced along 32W, south of 11N, based
on satellite imagery and wave diagnostic guidance. The wave is
moving westward at 10-15 kt. Scattered moderate convection is
observed from 03N to 08N and between 29W and 36W.

A tropical wave is along 65W, south of 20N, moving westward at 
10-15 knots. Scattered moderate to isolated strong convection is
noted from 10N to 19N and between 57W and 65W. The tropical wave 
will move through the eastern Caribbean Sea today, the central 
basin on Mon and the W Caribbean Tue. Showers are likely for 
Puerto Rico and the Virgin Islands tonight into Wed.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coast of
Guinea-Bissau near 12N16W and continues southwestward to 06N23W.
The ITCZ extends from 06N23W to 04N31W and then from 04N34W to
04N51W. A squall line is generating scattered showers and isolated
thunderstorms south of 10N and east of 20W. Scattered moderate 
convection is from 05N to 10N between 27W and 41W. 

GULF OF MEXICO...

A 1019 mb high pressure system centered between Bermuda and Hispaniola,
extends westward into the Gulf of Mexico. The pressure gradient 
between the ridge and lower pressures over Texas and Mexico result
in moderate to fresh SE-S winds west of 87W. Seas in these waters
are 3-6 ft. Elsewhere, light to gentle winds and slight seas 
prevail. No deep convection is noted across the basin. Hazy 
conditions due to agricultural fires in Mexico continue across 
most of the western Gulf and Bay of Campeche.

For the forecast, a relatively weak high pressure ridge will
continue to extend from the western Atlantic across the E Gulf 
into the upcoming week. This will maintain a weak pressure pattern
over the basin. Mostly moderate to fresh SE to S winds will exist
W of 87W through early Mon while light to gentle SE to S winds 
will exist E of 87W. The winds W of 87W will shift to W of 90W 
afterwards while winds east of 87W generally become light and 
variable, except S of 26N where they become gentle NE winds. Seas 
will be slight to moderate during the period. A cold front is 
expected to move across the NE Gulf Tue through Wed, followed by 
gentle to moderate W to NW winds. Fresh to strong winds will pulse
near the northern and western Yucatan Peninsula during the late 
afternoons and at night through the period. Hazy conditions due to
agricultural fires in Mexico continue across most of the western 
Gulf. Smoke is noted over the Bay of Campeche. 

CARIBBEAN SEA...

Please read the Tropical Waves section for details on the tropical
wave in the eastern Caribbean.

The previously-mentioned tropical wave in the eastern Caribbean is
producing a large area of showers and isolated thunderstorms that
is affecting the Lesser Antilles and nearby waters. Farther west,
an upper level trough extends from the western Atlantic to the 
western Caribbean and continues to transport tropical moisture 
northward. The combination of these systems will enhance the 
development of showers and thunderstorms over the islands in the 
central and eastern Greater Antilles during the next several days.
Heavy downpours are possible, especially in mountainous areas, 
leading to flash flooding. Please see your local weather service 
for more information. Generally dry conditions are present
elsewhere.

A weak pressure gradient prevails across the Caribbean Sea,
supporting moderate to locally fresh easterly winds in the central
and eastern Caribbean, and west of 85W. Seas in these waters are
3-6 ft. Light to gentle winds and slight seas are found in the
remainder of the basin. Hazy conditions continue to affect the
Gulf of Honduras due to agricultural fires over Central America.

For the forecast, high pressure over the western Atlantic will
maintain moderate to locally fresh trade winds across the basin,
except for pulsing fresh to strong winds in the Gulf of Honduras
at night through Mon night. Moderate to fresh trade winds over
the central Caribbean are forecast to increase to fresh to
strong speeds late Mon night through late Tue night, then
shifting to between 75W and 80W for the rest of the forecast
period. A tropical wave over the eastern Caribbean will continue 
to bring scattered to numerous showers and thunderstorms to this 
part of the Caribbean through Mon. Strong gusty winds and rough 
seas are likely with this activity. The wave may lose some 
definition as it moves across the central Caribbean during mid 
week. Dense smoke due to agricultural fires in Central America is 
likely to change over the Gulf of Honduras into the early part of 
the upcoming week. 

ATLANTIC OCEAN...

Please read the Tropical Waves section for details on the tropical
wave in the central Atlantic.

Broad ridging dominates the tropical Atlantic, anchored by a 1028
mb high pressure system near the Azores. A surface trough enters
the basin near 31N58W and continues southwestward to 26N66W. 
Isolated showers and thunderstorms are evident on satellite 
imagery ahead of the trough. Moderate to locally fresh S-SW winds 
and seas of 4-6 ft are present north of 25N and east of the trough
to 52W. Moderate to fresh easterly winds are occurring south of 
20N and west of 35W and south of 27N and east of 35W. Seas are 5-8
ft in the areas described, with the highest seas near 20N21W. 
Elsewhere, moderate or weaker winds and slight to moderate seas 
are prevalent.

For the forecast W of 55W, a trough extends from 31N58W to 26N66W
and to near the southeastern Bahamas. Scattered showers and 
thunderstorms moving eastward are north of 24N and east of 60W. 
Relatively weak high pressure elsewhere will change little during 
the next few days. The associated gradient will support mostly 
moderate winds and seas north of the Bahamas and off NE Florida by
Mon night as the high pressure shifts eastward ahead of a 
weakening cold front that will move across the waters north of the
Bahamas Tue into midweek. Moderate to fresh southerly winds will 
precede the front. Scattered showers and thunderstorms may 
accompany the front.

..MODEL ENSEMBLES HINTING CARIBBEAN DEVELOPMENT FIRST WEEK OF JUNE..

 


Just a heads up  will be away for the Memorial weekend  and will be taking my laptop with me.  I will publish brief updates here as often as I can.  Enjoy your long weekend.

Ralph

I was reviewing the model ensembles due to the greater than 20% probability for Caribbean development as the Global Tropics Hazard Outlook states in their latest update.


These are possible low pressures forming or tropical even a tropical cyclone.  No telling which track is correct so I will monitor models in the coming days and weeks.





  

..TROPICAL OUTLOOK MAY 23, 2023..

 


The National Hurricane Center is monitoring the surface trough of low pressure for development as it moves into the Atlantic. Upper-level conditions are not favorable; however, some of the models suggest some development into a tropical or sub-tropical system could occur as it tracks north-northeast. If it were to develop, it would be a short-lived system.
