NWS National Hurricane Center Miami FL 
0605 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 0000 UTC surface analysis and satellite imagery through 
0350 UTC.

...TROPICAL WAVES...

An eastern Atlantic tropical wave extends along 18W, from 11N to 
03N, moving west at 10 knots. Scattered moderate convection is 
observed from 04N to 09N between 14W and 22W.

An eastern Atlantic tropical wave extends along 32W, from 11N to 
01N, moving west at 10 knots. Scattered moderate convection is 
observed from 03N to 08N, between 30W and 36W.

A central Atlantic tropical wave extends along 45W, from 11N to 
01N, moving west at 10 knots. Associated convection is isolated 
and weak.

A western Atlantic tropical wave extends along 58W, from 11N to 
01N, moving west at 10 knots. Scattered moderate convection is 
observed over South America from 02N to 07N between 53W and 63W.

A Caribbean Sea tropical wave extends along 71, from 13N to 03N. 
Scattered moderate convection is observed over Venezuela and 
Colombia from 05N to 12N, between 69W and 76W.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Guinea-Bissau near 
12N16W to 07N21W. The ITCZ continues in segments interrupted by 
tropical waves from 07N21W to 05N30W, from 05N34W to 06N43W, and 
from 06N47W to 05N51W. In addition to the convection described 
in the tropical wave section above, scattered moderate 
convection is observed from 06N to 08N between 37W and 41W. 

...GULF OF MEXICO...

Weak high pressure prevails across the Gulf waters. An abundance 
of tropical moisture is supporting scattered moderate convection 
from 21N to 30N between 86W and 92W. Gentle to moderate winds 
prevail across the basin, with seas in the 1-3 ft range.

For the forecast, a weak pressure pattern will support gentle to 
moderate winds and slight seas across the basin through the end 
of the week, with occasional fresh pulses along the W coast of 
Yucatan. 

...CARIBBEAN SEA...

The gradient between high pressure in the subtropical Atlantic 
and lower pressure in the SW Caribbean is supporting moderate to 
locally fresh trade winds in the eastern Caribbean, with the 
strongest winds offshore near the border of Colombia and 
Venezuela. Winds are gentle to moderate in the NW Caribbean, 
with the strongest winds in the Gulf of Honduras. Seas are 3-5 
ft across the majority of the basin, other than 1-3 ft seas in 
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 from 31N74W to S Florida near 
27N80W. NW of the front, 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. In the central Atlantic, a cold front has 
dipped into the area tonight, extending from 31N33W to 29N38W to 
31N45W. N of the front winds are moderate from the NW with 6-8 
ft seas. S of the front winds are moderate to fresh from the W-
SW with 4-6 ft seas. In the eastern Atlantic, a 1022 mb high 
pressure centered near 26N24W dominates the pattern. Winds are 
light to gentle near the high, increasing to moderate to fresh 
NE winds south of 25N 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 Fri. A broad area of low pres 
may form north of the Bahamas on Fri with increasing winds and 
building seas over the waters east of the Bahamas on Sat.
