TAMPA, Fla. — Another area of disturbed weather is joining Tropical Storm Josephine in the Atlantic basin: Invest 96-L.
Invest 96-L is located over eastern North Carolina. The National Hurricane Center forecasts a medium chance of developing into a subtropical or tropical cyclone. It has a 40-percent chance of developing over the next two days and a 50 percent chance of development over the next five days as it tracks east into the open waters of the Atlantic.
If Invest 96-L becomes a named tropical storm, the next name on the 2020 Atlantic Hurricane Names List is Kyle. The earliest 11th Atlantic named or "K" storm formation on record is Katrina on August 24, 2005.
Hurricane Katrina was a Category 5 tropical cyclone that occurred in August 2005, which caused over 1,200 deaths and $125 billion in damage, particularly in the city of New Orleans.
Spaghetti models are in general agreement that Invest 96L will move east-northeastward across over the open Atlantic.
The European model forecast that the system will be short-lived. The GFS American model forecasts that the system will continue to develop.
The storm does not pose a threat to Florida.
An invest is simply short for "investigative area." It’s also known as an area of interest. It is a designated area of disturbed weather that is being monitored for potential tropical cyclone development.
Once the National Hurricane Center declares an investigative area, spaghetti models are run on the system to project the future track possibilities.
Invests are numbered from 90 to 99, followed by a suffix letter "L" in the North Atlantic basin, "E" and "C" in the Eastern and Central Pacific basins (respectively), or "W" in the Western Pacific basin.
Numbers are rotated within the season and are re-used as necessary (the next invest after 99 would be numbered 90).
This naming system gives forecasters a way of identifying the individual weather systems and the important information related to it. Also, when there multiple tropical disturbances, it is easier for meteorologists to communicate what invest they are talking about.
The designation of a system as an invest does not necessarily correspond to any particular likelihood of development of the system into a tropical cyclone.
