Well we have minimal TS Bret nearing Trinidad and Venezuela, which is extremely unusual as most tropical systems do not get that far south. That storm is likely going to dissipate in the Caribbean However, the as yet unnamed system in the Central Gulf of Mexico, is likely to bring torrential rains to much of the Gulf Coast over the next several days, even if it never becomes an official tropical storm (it will be Cindy, if it's named). I do like the NHC's new policy of providing much more detailed forecasts on "potential tropical systems." The WU blog also has a nice write-up, especially on the potential for heavy rains:
The slow-moving system now known as PTC 3 could dump 10” to 20” of rain on parts of the central Gulf Coast this week. Models do not indicate that PTC 3 is likely to become a strong tropical storm or hurricane. Even if it does become Cindy, its sustained winds may never top 50 mph. However, a system like this doesn’t need to reach tropical storm status in order to cause major havoc. This became clear with last year’s “no-name” floods in Louisiana—the nation’s worst disaster of 2016, with more than $10 billion in damage.
