NOAA: Invest 99L 2019 Path, Spaghetti Models

MIAMI, Florida – NOAA’s National Hurricane Center issued a Tropical Weather Outlook at 8 a.m. Eastern Daylight Time on Saturday, September 21, 2019, due to the presence of Invest 99L that may become a tropical cyclone over the Atlantic Ocean.

If Invest 99L does become a tropical storm, the next name on the 2019 Atlantic Hurricane names list is Tropical Storm Karen.

Invest 99L 2019 Projected Path

Invest 99L is a tropical wave located several hundred miles east of the Windward Islands that is producing a large area of disorganized showers and thunderstorms (marked with an orange “X”).

Invest 99L is expected to move quickly westward at about 15 to 20 mph during the next day or two.

NHC forecasters say that a tropical depression could form on Sunday or early next week while the system crosses the Windward Islands.

Upper-level winds are forecast to become less conducive for development by the middle of next week once Invest 99L moves out of the northeastern Caribbean Sea.

A NOAA Hurricane Hunter aircraft is scheduled to investigate this system this afternoon, if necessary.

Regardless of development, heavy rainfall is possible over much of the Lesser Antilles over the weekend, and interests on those islands and Puerto Rico should monitor the progress of this disturbance.

Invest 99L has a 60% chance of tropical cyclone formation within the next five days and a 50% chance within the next 48 hours.

Invest 99L 2019 Spaghetti Models

Spaghetti models are in strong agreement that Invest 99L will track westerly over the western Atlantic.

Computer models forecast a northwesterly turn when Invest 99L enters the eastern Caribbean followed by a curve to the north towards Puerto Rico.

NOAA forecasts an ‘above-normal’ 2019 Atlantic Hurricane Season which runs from June 1 through November 30.
