18Z MODEL RUN, INTENSITY MODEL RUN AND RAINFALL OUTLOOK AND MODEL

So far we are looking at a rain maker as this system tracks north into the Gulf of Mexico.  You can't rule out a sub-tropical or weak tropical cyclone as it moves north across the Gulf.  Looks like a wet holiday weekend for a portion of the Southeast.

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

1. A broad surface low centered near the coast of northeastern Belize
continues to produce a large area of cloudiness and showers
extending from the northwestern Caribbean Sea across Cuba and into
the Florida Straits.  Little development is expected during the
next couple of days due to strong upper-level winds and proximity to
the Yucatan Peninsula.  However, environmental conditions are then
forecast to become more conducive for development, and a subtropical
or tropical depression could form this weekend over the eastern or
central Gulf of Mexico.  Regardless of development, locally heavy
rainfall is possible across western Cuba and the Cayman Islands
during the next few days, and over much of Florida and the
northern Gulf Coast during the weekend. For more information on the
heavy rain threat, please see products issued by your local weather
office. The next Special Tropical Weather Outlook on this system
will be issued by 800 PM EDT.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.

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

A broad surface low centered just east of Belize is producing a
large area of cloudiness and showers extending from the northwestern
Caribbean Sea across Cuba and into the Florida peninsula.  Little
development is expected during the next couple of days due to strong
upper-level winds and proximity to the Yucatan Peninsula of Mexico.
However, gradual subtropical or tropical development is possible
late this week while the system moves slowly into the central or
eastern Gulf of Mexico.  Regardless of development, locally heavy
rainfall is possible across western Cuba, the Cayman Islands, and
much of Florida during the next several days.  For more information
on the heavy rain threat, please see products issued by your local
weather office. The next Special Tropical Weather Outlook on this
system will be issued by 800 AM EDT on Wednesday. 

* Formation chance through 48 hours...low...near 0 percent.

18z MODEL RUN FOR INVEST 90L MAY 22, 2018... 0427 PM EDT

Here are the latest 18z model run for INVEST 90L, and they are all over the Place.  Looking at a disorganized system so what can you expect out of the models, nothing much.  Anyhow this system should slowly track northward in the coming days.  Looks like this system will basically be another rain producer so those area from Louisiana to Florida should be ready for torrential rains and possible flooding into the Memorial Day weekend...RTW
