AFTERNOON TROPICAL OUTLOOK JUNE 6, 2018...0228 PM EDT

National Hurricane Center
...TROPICAL WAVES...

An Atlantic Ocean tropical wave is along 19W/20W from 14N
southward. Precipitation: isolated moderate to locally strong
rainshowers are from 06N to 08N between 18W and 22W.

An Atlantic Ocean tropical wave axis is along 43W/44W from 13N
southward, moving westward 10 to 15 knots. Precipitation: isolated
moderate ITCZ-related rainshowers are from 07N southward between
40W and 50W.

A Caribbean Sea tropical wave is along 17N68W 14N70W 10N71W,
moving westward 15 knots. Precipitation: no significant deep
convective precipitation is apparent in satellite imagery.
The wave will pass due south of Hispaniola for the rest of the day 
today.

Peninsula, moving westward 10 to 15 knots. no significant deep
convective precipitation is apparent in satellite imagery.

There are no signs of tropical cyclone formation at this time...RTW 
Please note that this morning I added a new wave on the map but I forgot
to add NHC discussion on that wave they were reporting on.  I corrected that
my apology...RTW
 

TROPICAL OUTLOOK JUNE 6, 2018...0931 AM EDT

National Hurricane Center
...TROPICAL WAVES...

A tropical wave has emerged from the African coast over the 
evening hours, located along 18W and S of 14N. The wave is 
associated with scattered moderate convection between the African 
coast and 20W.

A low amplitude tropical wave axis is along 42W and S of 12N 
moving west at 10-15 kt. No significant convection is related to 
this wave at this time.

A tropical wave axis is along 68W and S of 17N, moving west 
across the eastern Caribbean at 15 kt. No convection is related 
to this wave at this time due to the presence of African dust over
the E Caribbean. The wave will pass due south of Hispaniola 
through today.

A tropical wave axis is along 89W and S of 20N, moving westward 
at 15 kt across the Yucatan Peninsula. Abundant moisture is 
related to the wave based on water vapor animation. The wave is 
generating scattered showers and isolated tstms over parts of 
northern Central America and the Yucatan Basin, mainly west of 
85W. This moisture will continue spreading across the Yucatan area
through the next 24 hours.

AFTERNOON TROPICAL OUTLOOK JUNE 5, 2018...0304 PM EDT

National Hurricane Center
...TROPICAL WAVES...

A low amplitude tropical wave axis is along 40W S of 12N moving 
west at 15-20 kt. Isolated moderate convection is noted where the
wave meets the ITCZ.

A tropical wave axis along 61W/62W S of 16N is moving west across
the eastern Caribbean at 15 kt. A surge of moisture associated 
with the wave is evident from TPW imagery. The Windward Islands
are currently reporting showers in the vicinity with the wave 
passage. The wave will cross S of Puerto Rico today, and will 
reach Hispaniola on Wed. Convection will be limited with the wave
passage due to the presence of African dust over the NE Caribbean.
A recent scatterometer pass indicates the wind shift related to 
the wave axis.

A tropical wave axis along 86W S of 20N is moving westward at 15 
kt across the NW Caribbean and Central America. Abundant moisture
is related to the wave based on TPW animation. The wave is
generating scattered showers and isolated tstms over parts of
northern Central America and the NW Caribbean. Moisture from this
wave will spread across the Yucatan Peninsula late today.

TROPICAL OUTLOOK JUNE 5, 2018...0923 AM EDT

National Hurricane Center
...TROPICAL WAVES...

A tropical wave axis is along 38W/39W S of 13N in the eastern 
Atlantic, moving west at 15 kt. TPW imagery depicts abundant 
moisture in the wave environment south of 10N. Isolated moderate 
convection is noted where the wave meets the ITCZ.

A tropical wave axis along 60W/61W S of 14N is moving west into 
the eastern Caribbean at 10-15 kt. A surge of moisture associated 
with the wave is evident from TPW imagery. Scattered moderate 
convection is east of the wave near the coast of South America. 
The passage of the wave will bring some shower activity across 
Windward Islands today.

A tropical wave axis along 85W S of 18N is moving westward at 10-
15 kt across Central America. Abundant moisture is related to the
wave based on TPW animation. A cluster of moderate to strong
convection persists over the SW Caribbean in the wake of the wave
axis. The wave is also inducing a cluster of moderate to isolated
strong convection in the eastern Pacific S of Panama. Showers 
from this wave will spread across the Central America today, and 
reach the Yucatan Peninsula tonight.
-----------------------------------------------------------------
There are no signs of tropical cyclone formation at this time...RTW

I continue to monitor the Northwest Caribbean into next week. Although
high pressure seems in control at this time and may be in control next
week the GFS continues to insist on some development in this region
of the Caribbean. GFS was the only one insisting on Alberto when other
models were not picking up on Alberto's development, so I don't want
ignore this model...RTW

TROPICAL WEATHER OUTLOOK JUNE 4, 2018...0345 PM EDT

National Hurricane Center
...TROPICAL WAVES...

A tropical wave is over the eastern Atlantic with axis extending 
from 14N31W to 01N32W, moving westward at 15 kt. TPW imagery 
depicts abundant moisture in the wave's environment, and the wave
coincides with a trough at 700 mb. Scattered moderate convection 
is noted where the wave meets the ITCZ. 

A tropical wave is along 58W S of 14N, moving westward at 10-15 
kt. A modest surge of moistened air is associated with the wave 
based on the TPW imagery. Scattered moderate and isolated strong 
convection is from 08N-10N between 53W and the coast of NW Guyana.
Moisture associated with this wave will reach the Windward Island
late today producing some shower activity.

A tropical wave is over the Caribbean Sea with axis along 80W S 
of 17N. This wave is moving westward at 10-15 kt. Abundant 
moisture is related to the wave based on the TPW animation. A 
cluster of moderate to isolated strong convection is between the 
wave axis and the coasts of western Panama and Costa Rica, mainly 
S of 11N. The wave is also helping to induce another cluster of 
moderate to isolated strong convection on the EPAC region. 
Moisture associated with this wave will spread across the 
remainder of Central America today and tonight, reaching the 
Yucatan Peninsula late Tue.

TROPICAL OUTLOOK JUNE 4, 2018... 0928 AM EDT

National Hurricane Center
...TROPICAL WAVES...

A tropical wave is over the eastern Atlantic with axis extending 
from 14N31W to 01N32W, moving westward at 20 kt. TPW imagery 
depicts abundant moisture in the wave's environment and model 
diagnostics show a trough at 700 mb. Scattered moderate convection
is where the wave meets the ITCZ. 

A tropical wave is along 55W S of 14N, moving westward at 15 kt. 
The wave is depicted as a broad trough of moisture on TPW imagery.
Scattered moderate and isolated strong convection is from 08N-10N
between 53W and the coast of NW Guyana.

A tropical wave is over the central Caribbean with axis along 78W
S of 16N. This wave is moving westward at 15 kt. The wave is 
rather ill-defined at the surface at this time, and the axis
extends into the EPAC region. A cluster of moderate to strong 
convection is ahead of the wave axis over the SW Caribbean. 
This is most likely due to the monsoon trough extending from the 
E Pacific.

3. There are no signs of tropical cyclone formation with wave 1 and 2...RTW

4. Off the coast of Africa there still is Sahara dry air and Dust. Doesn't seem to be 
affecting the monzoon thunderstorm activity along the inter tropical convergence zone (ITCZ) along and south of the 10° West Latitude.

5. I will be monitoring the Northwest Caribbean again during the 2nd week
of June since the GFS model is once again insisting on development in this region...RTW

AFTERNOON TROPICAL OUTLOOK

1.  A tropical wave near 22-23° West is lacking thunderstorm activity due to Sahara Air Layer or Dry Air and Dust.  There are no signs of organization at this time.  RTW

2.  A tropical wave approaching the Brazilian coast near 56-55° West has some thunderstorms associated with it but southwesterly shear ahead of the wave should prevent any further storm development before the wave makes its way onshore.  RTW
