TROPICAL WEATHER OUTLOOK AND STORM INVEST UPDATE JUNE 11, 2018... 0405 PM EDT

 National Hurricane Center
...TROPICAL WAVES...

Currently, three tropical waves are observed between the coast of
Africa and the Lesser Antilles. 

A tropical wave is along 25W from 02N-12N. This wave shows up 
as a low amplitude moisture surge on the TPW product. Currently, 
showers are limited near the wave's axis. African dust surrounds 
the wave limiting convection.

A tropical wave extends its axis from 14N42W to 05N45W. This wave
was repositioned after analyzing current observations and model 
diagnostics. This wave shows up as a low amplitude moisture surge 
on the TPW product. Scattered showers are near the southern end of
the wave's axis south of 10N between 43W-48W. Saharan dust 
surrounds the northern half of the wave limiting convection.

Another tropical wave is along 54W/55W from 05N-16N. The wave 
coincides with a surge of moistened air, as noted in TPW imagery.
This wave was repositioned after analyzing this data, current
observations, and model diagnostics. Scattered showers are noted 
south of 08N between 55W-58W.

A tropical wave is moving across Hispaniola. This wave was 
repositioned after analyzing current observations/satellite
imagery, and model diagnostics. Its axis is along 70W south of 
19N. Scattered showers are noted along the axis.

A tropical wave is moving across the Bay of Campeche, with axis  
along 92W. This wave is forecast to weaken as it enters the EPAC 
region.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Mon Jun 11 2018

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

A broad area of showers and thunderstorms has persisted over the
southwestern Caribbean Sea for the past several hours. This activity
is associated with a tropical wave over northwestern Venezuela and
a surface trough located just east of Nicaragua interacting with a
large upper-level trough.  Little development of this area of
disturbed weather is expected over the next few days due to
interaction with Central America and the Yucatan Peninsula. However,
environmental conditions could become somewhat more conducive for
some limited development when the system moves into the southwestern
Gulf of Mexico by the end of the week.  Regardless of development,
this disturbance will produce locally heavy rainfall across portions
of Nicaragua, Honduras, Belize, Guatemala, and the Yucatan Peninsula
through Thursday.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

TROPICAL OUTLOOK JUNE 11, 2018...0931 AM EDT

National Hurricane Center
...TROPICAL WAVES...

Currently, three tropical waves are observed between the coast of
Africa and the Lesser Antilles. 

A tropical wave is along 22W from 02N-12N. This wave shows up 
well as a low amplitude moisture surge on the TPW product. 
Currently, convection is limited near the wave's axis. African 
dust surrounds the wave limiting convection.

A tropical wave is along 32W/33W from 02N-13N moving westward 15 
to 20 kt. This wave shows up well as a low amplitude moisture 
surge on the TPW product. Scattered showers are near the southern 
end of the wave's axis. Saharan dust surrounds the wave limiting 
convection.

Another tropical wave is along 47W/48W from 03N-13N. The wave 
coincides with a surge of moistened air. Scattered moderate 
convection is noted from 06N-08N between 42W-47W.

A tropical wave is moving across Hispaniola. Its axis is along 
71W south of 19N, moving westward at 15 kt. Scattered showers and
isolated tstms are noted over Hispaniola in association with this
system, forecast to move west through the central Caribbean today
reaching the west Caribbean waters on Tue and Wed. 

A tropical wave is moving across the Yucatan Peninsula and 
Guatemala, with axis along 91W. This wave is forecast to weaken as
it enters the EPAC region.
-----------------------------------------------------------------
I will continue to monitor the Northwest and Southern Caribbean for 
development even though the GFS has now changed the forecast to No 
development.  For the past two weeks the model has been persistently
saying development and now it has changed its tune.  So just to being 
cautious, I will continue to monitor during this week...RTW

NOTICE TO MY VIEWERS:  I WILL BE CELEBRATING MY 38 WEDDING
