southward, moving west at 15 kt. Isolated moderate convection is 
from 07N-09N between 36W-43W.

An E Caribbean tropical wave extends its axis from 20N70W to

the Bay of Campeche. See above. 

CARIBBEAN SEA...

A tropical wave is over the E Caribbean. Refer to the section

An upper level low is centered S of Hispaniola near 17N73W.  
Upper level cyclonic flow covers the entire Caribbean. An area of
diffluent flow is over the NW Caribbean S of Cuba. 

The eastern part of the eastern Pacific monsoon trough is along 
10N from 74W in Colombia beyond southern Costa Rica. Scattered
moderate to isolated strong convection is from 07N-11N between 
72W-83W.

Fresh to strong winds will prevail in the south central Caribbean,

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Thu Aug 30 2018

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

The National Hurricane Center is issuing advisories on Potential
Tropical Cyclone Six, located southeast of the Cabo Verde Islands.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

A tropical wave located over the north-central Caribbean Sea is
producing a large area of cloudiness and thunderstorms extending
from Hispaniola northeastward across the northeastern Caribbean Sea
and adjacent Atlantic waters. This activity is forecast to spread
westward to west-northwestward, but strong upper-level winds are
expected to prevent any significant development of this system
during the next several days. Environmental conditions could become
more conducive when the system reaches the eastern Gulf of Mexico
early next week. Regardless of development, this system could
produce enhanced rainfall across portions of Hispaniola, the
Bahamas, the Turks and Caicos, and Florida into early next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...10 percent.

Public Advisories on Potential Tropical Cyclone Six are issued
under WMO header WTNT31 KNHC and under AWIPS header MIATCPAT1.
Forecast/Advisories on Potential Tropical Cyclone Six are issued

-----------------------------------------------------------------
As for the storm invest I would not be to bummed out about it.  The
EURO has been gradually suggesting a weaker system if at all.  As
for other models they don't suggest any development at all.  
We still could see some rains and storms labor day as the
northern axis of this wave moves across the area.  Regardless of
development or not we should be storm ready as we enter the busiest
time of the season...RTW

ACCIDENT WHILE DOING UPDATE DELAYS MY BLOG POST AND WEBSITE PUBLISH



Had an accident while working at my desk.  Cup of water spilled all over the top of my laptop keyboard.  I had to quickly turn it over and unplugged it in the middle of an unsaved update to my website.  I had to take laptop keyboard out and dry it with a blow driver.  Luckily my quick action of turning it over immediately and the pad under the keyboard prevented water from seeping down and shorting out components.  I am back up and running and working on updates and blog update as well.  I apologize for the inconvenience.
