93L: Tropical Storm Jerry???
An area of low pressure that lingered along the Florida coast for several days finally entered the Gulf of Mexico Thursday morning — prompting local officials to more readily monitor weather reports.

Since landfall is expected Saturday between the Florida Panhandle and Southeast Louisiana, 93L probably does not have time to become fully tropical. If 93L makes landfall Saturday, it should not have winds stronger than about 55 mph. The GFDL, HWRF, and SHIPS intensity models all keep 93L's winds below 55 mph. If the storm spends an extra day over water and makes it to Texas, as the ECMWF model predicts, 93L could become fully tropical and make landfall as a strong tropical storm with 60-70 mph winds. However, there is plenty of dry air in the environment, and I don't think the storm will be able to intensify to a strong tropical storm.
Update:
From Dr. Jeff Masters' WunderBlogStorms that start off as large, non-tropical systems like 93L typically take several days to organize and become fully tropical, and 93L will not have time to become anything worse than a minimal tropical storm. The storm is capable of dumping some heavy rains along its path--radar estimated precipitation from the Tallahassee radar (Figure 1) were as high as three inches. As 93L becomes more tropical in nature, it will be able to generate higher rain amounts. But, with the storm expected to move inland by Saturday afternoon, it does not appear 93L has time to generate the kind of tropical rains that would make it a serious flood threat.
