The National Hurricane Center is monitoring widespread cloudiness and showers extending from the northwestern Caribbean Sea across Cuba and the Florida 
peninsula are associated with the interaction of a large upper-level low with a weak surface trough.  

While environmental conditions are expected to be unfavorable for development during the next couple of days, 
some gradual development is possible later this week while the system moves into the central or eastern Gulf 
of Mexico, stated this morning's NHC update.

Regardless of development, locally heavy rainfall is possible across western Cuba and Florida over the next 
several days, per the update.  

The next Special Tropical Weather Outlook on this system will be issued by 7 p.m. CST tonight.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
