..TROPICAL WEATHER OUTLOOK.. ..SEVERE WEATHER OUTLOOK AND RAINFALL OUTLOOK..

 


I AM MONITORING A DISTURBANCE IN THE GULF TRACKING EAST.  IF THIS DISTURBANCE HOLDS TOGETHER, IT COULD ENHANCE SHOWERS AND STORM FOR FLORIDA IN THE COMING DAYS.

ENSEMBLE MODELS CONTINUE TO SUGGEST LOW COMING OUT OF THE CARIBBEAN AND SOME OUT OF THE GULF.  I AM ALSO KEEPING AN EYE IN THOSE OCEAN BASIN AS THESE ARE AREAS TO MONITOR IN JUNE.

I AM SEEING 5 TROPICAL WAVE MARCHING WEST ACROSS THE CARIBBEAN AND THE ATLANTIC.  NONE OF THESE WAVES ARE SHOWING SIGNS OF ORGANIZATION AT THIS TIME.

1205 UTC Tue May 30 2023

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 
1020 UTC.

...TROPICAL WAVES...

An eastern Atlantic tropical wave extends along 21W, from 11N to 
03N, moving west at 15 knots. Scattered moderate convection is 
observed from 03N to 08N between 18W and 25W.

An eastern Atlantic tropical wave extends along 33/34W, from 11N 
to 01N, moving west at 10 knots. Scattered moderate convection is 
observed from 02N to 09N, between 27W and 36W.

A central Atlantic tropical wave extends along 46/47W, from 11N 
to 01N, moving west at 10 knots. Scattered moderate isolated
strong convection is noted from 08N to 11N between 43W and 49W.

A weak, western Atlantic tropical wave extends along 60W, from 
11N to 01N, moving west at 10 knots. Isolated to scattered 
moderate convection is noted from 01N to 09N between 55W and 62W.

A Caribbean Sea tropical wave extends along 72/73W, from 13N to 
03N, moving west at 10-15 kt. Scattered moderate isolated strong
convection is observed over western Venezuela and eastern 
Colombia near the wave axis from 07N to 11N.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Guinea near 10N14W 
to 07N21W. The ITCZ continues in segments interrupted by tropical 
waves from 07N21W to 05N32W and from 05N35W to 05N44W. In 
addition to the convection described in the tropical wave section 
above, scattered moderate convection is observed from 02N to 06N
between 08W and 14.5W, and from 07N to 10N between 37W and 42.5W.

GULF OF MEXICO...

A surface trough extends from the west coast of the Yucatan 
Peninsula northward to the central Gulf of Mexico near 25N90W. An 
upper-level trough extends across the Gulf from western Louisiana
to the Yucatan Peninsula. Due to low-level convergence from the 
surface trough and upper-level diffluence just east of the upper- 
trough axis, numerous moderate isolated strong convection is noted
over the central Gulf from 23N to 27.5N between 87.5W and 91W, 
strongest from 23N to 25.5N between 88W and 89.5W. Weak surface 
high pressure of 1013 mb is centered near 27.5N86W. A weak cold 
front extends from Apalachicola, FL to New Orleans, LA.

Winds across the Gulf of Mexico are mostly gentle to moderate with
seas 3 ft or less. However, locally stronger winds and higher seas
are possible within and near the aforementioned convective area.

For the forecast, a surface trough or surface low pressure could 
form over the south-central or southeastern Gulf tonight or Wed 
and potentially linger over the eastern Gulf into Fri. Moderate 
winds are forecast in the area, but there is a chance that the 
trough or low could develop fresh to strong winds later this week.
Enhanced showers and thunderstorms are also possible across the 
eastern half of the Gulf Wed into Fri. Elsewhere, over the western
Gulf, high pressure should lead to gentle to moderate winds into 
the weekend, with occasional fresh pulses along the W coast of 
Yucatan.

CARIBBEAN SEA...

An upper-level trough axis extends from western Louisiana to the
Yucatan Peninsula to El Salvador. East of the upper-trough axis,
upper-level diffluence is enhancing scattered moderate convection
across the NW Caribbean north of 17N and west of 75W to 88W.
Similar activity is noted from 13.5N to 17N and west of 81.5W. The
east Pacific monsoon trough is enhancing scattered thunderstorms
south of 12N between 75.5W and 81W. No major precipitation areas 
are noted east of 75W, except for inland over Venezuela, where 
moderate to strong convection is occurring over portions of that 
country.

Moderate trades prevail across the eastern and central Caribbean,
locally fresh near the coast of western Venezuela and Colombia.
Seas are 3-4 ft across the eastern and central Caribbean, except
for 4-5 ft in the south-central basin. Light to gentle winds 
prevail over the western Caribbean, except for moderate SE over 
the Gulf of Honduras. Seas are 1-3 ft across the NW Caribbean.

For the forecast, 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.

ATLANTIC OCEAN...

A weak stationary boundary extends southwestward from a 1013 mb
low pressure near 34N71W to 31N73W to S Florida near 27N80W. A 
1013 mb high pressure is centered NW of the front near 30N78W, 
where winds are light to gentle with 2-4 ft seas. E of the front, 
winds are gentle to moderate from the S with 3-5 ft seas.
Scattered moderate isolated strong convection extends south-
southeastward from the aforementioned low pressure N of the area,
and these showers and thunderstorms cover the area north of 28N
between 66.5W and 71W. Scattered moderate convection is also noted
over the southeast Bahamas area, mainly south of 25N between 71W
and 76.5W.

In the central Atlantic, a cold front extends from 31N31W to 
29N38W to 29.5N41W, stationary to 31N44W. N of the front, winds 
are moderate from the NW with 6-8 ft seas. S of the front, winds 
are fresh from the WSW with 5-7 ft seas. In the eastern Atlantic,
a 1020 mb high pressure centered near 26N24W dominates the 
pattern. Winds are light to gentle near the high, increasing to 
fresh NE winds south of 24N between the coast of Africa and the 
Cabo Verde Islands, where seas are 6-8 ft. Throughout the basin 
south of 20N, winds are moderate to fresh from the E with 5-7 ft 
seas.

For the forecast W of 55W, a weak pressure pattern will result in
quiescent conditions through Thu. A broad area of low pres is 
likely to form by late this week, extending across the western 
Atlantic from Florida to well south of Bermuda. Increasing winds 
and building seas are likely over the waters east of the Bahamas 
on Sat. Expect increasing coverage of showers and thunderstorms 
across the western Atlantic by Thu.

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 
1015 UTC.

...SPECIAL FEATURES...

Western Atlantic Gale Warning: A 1007 mb frontal low centered near
Lake Okeechobee, Florida is forecast to strengthen and drift 
northeastward into the western Atlantic for the next couple of 
days, then move north of 31N by Sat night. The pressure gradient 
between the high over the northeastern U.S. and the low will 
support fresh to strong N-NW to N-NE winds and 10 to 13 ft seas 
in large NE swell over the northeast Florida offshore waters 
beginning this afternoon, spreading southward to near Cape 
Canaveral through Sat afternoon. These winds will reach gale- 
force offshore northeast Florida this afternoon through Sat 
morning. Seas will build higher and peak at 15 to 19 ft during the
strongest winds. Winds and seas will diminish Sat night into Sun 
as the low weakens and moves north of the area.

Please see the latest High Seas Forecast at website 
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for further 
details.

...TROPICAL WAVES...

A new tropical wave has been analyzed in this map, with axis along
15W between 02N-12N. At this time, scattered moderate convection
prevails within this wave mainly E of 20W. 

An eastern Atlantic tropical wave extends its axis along 26W from
12N southward, moving westward at around 10 to 15 kt. Scattered 
showers are noted from 02N to 10N between 22W and 32W.

A central Atlantic tropical wave extends its axis along 43W from 
12N southward, moving westward at 10 to 15 kt. Scattered showers
are noted along the wave's axis. 

A tropical wave extends its axis along 57W from 12N southward 
into Suriname, and moving westward at 10 to 15 kt. Scattered 
moderate convection is present from 07N to 12N between 49W and 
57W.

...MONSOON TROUGH/ITCZ...

A monsoon trough reaches southwestward from inland Senegal across
the coast near the Senegal-Gambia border to 12N18W. The ITCZ 
extends westward from 08N17W to 07N24W, then resumes from 01N27W 
to 00N42W. The convection in the vicinity of these boundaries is 
described in the Tropical Waves section above.

...GULF OF MEXICO...

A cold front curves westward from a 1007 mb low near Lake 
Okeechobee, Florida across the east-central Gulf to near 26N89W.  
A surface trough continues from that point to 28N93W. Another
trough extends from the low to western Cuba. Moderate to fresh NE
to ENE winds and seas of 3 to 5 ft are noted behind the cold 
front across the northeastern Gulf. Gentle to moderate NNE to E 
winds with 1 to 3 ft seas prevail for the rest of the Gulf, 
including the Bay of Campeche and Florida Straits.

For the forecast, moderate to fresh N to NE winds will prevail N 
of 25N and E of 90W through Sat. Weak high pressure will dominate 
the basin through the next several days, supporting gentle to 
moderate winds. Slight seas will build to moderate through Sat.

...CARIBBEAN SEA...

The western end of the Atlantic Ridge extends southwestward 
across Hispaniola to just east of Nicaragua. Convergent southerly 
winds near monsoon trough are triggering scattered showers and 
isolated thunderstorms at the south-central basin, just north of 
Colombia and Venezuela. Aided by strong upper-level divergence, 
scattered showers and thunderstorms are evident over eastern Cuba 
and nearby Caribbean waters.

Gentle to moderate ESE to S winds and seas at 3 to 5 ft are noted
for the eastern and north-central basin. NE to E gentle winds 
with 2 to 4 ft seas dominate the south-central and southwestern 
basin. Light to gentle WSW to W winds and seas of 1 to 3 ft
prevail for the remainder of the basin.

For the forecast, elongated troughing N of the basin will help to
maintain a weak pres gradient across the central and western
Caribbean through today, supporting light to gentle winds. The 
Azores High will continue to support moderate E-SE trade winds 
through the weekend over the E Caribbean, diminishing slightly 
into early next week. 

...ATLANTIC OCEAN...

Please read the Special Features section about a Gale Warning in 
the western Atlantic.

A stationary front extends southwestward from off the Georgia-
South Carolina coast near 31N78W to a 1007 mb low near Lake 
Okeechobee, Florida. Scattered moderate convection prevails across
the western Atlantic mainly W of 65W. At the eastern Atlantic, an
upper-level low near 30N30W is generating scattered moderate 
convection north of 27N between 26W and 32W.

Moderate to fresh northerly winds and seas of 5 to 8 ft are noted
off the northeast Florida coast north of 28N between 80W and the 
Georgia-northern Florida coast. Gentle to moderate SW to S winds 
with 4 to 6 ft seas are evident from 20N to 31N between 73W and 
80W. Moderate to fresh ESE to S winds and seas at 5 to 7 ft are 
noted north of 20N between 31W and 73W, and from 06N to 20N 
between 30W and the Lesser Antilles. Gentle to moderate NE to E 
trades and seas of 3 to 5 ft prevail elsewhere. 

For the forecast W of 55W, scattered showers and tstms prevail 
across the western Atlantic, mainly west of 65W. The low pres is 
forecast to strengthen and drift over the W Atlc through today, 
then move N to near 31N79W by Sat morning before moving north of 
the area by Sat evening. Fresh to strong N to NE winds and large 
NE swell will prevail across the NE Florida offshore waters today,
spreading southward to near Cape Canaveral through Sat before the
low moves N of the area. N to NE gales are expected offshore 
northern Florida this afternoon through Sat morning. High pressure
ridging will lead to quiescent conditions Sun and Mon.

200 PM EDT Thu May 25 2023

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Southwestern Atlantic:
Disorganized showers and thunderstorms off the coast of the 
southeastern United States are associated with a front and trough 
of low pressure. A non-tropical area of low pressure is expected 
to form along the frontal boundary within the next day or so. The 
system appears unlikely to become a subtropical or tropical cyclone 
since it is forecast to remain frontal while moving generally 
northward and inland over the Carolinas this weekend.

Regardless, the system is likely to produce gusty winds and 
dangerous surf and rip current conditions along portions of the 
southeastern United States late this week and into the weekend. 
Heavy rainfall is expected in portions of the Carolinas with 
hazardous marine conditions expected over the coastal and 
offshore waters where gale warnings are in effect. For more 
information, see products from your local National Weather
