MIAMI, Florida – NOAA’s National Hurricane Center in Miami, Florida issued a Tropical Weather Outlook at 2 p.m. on Monday, August 14, 2017, due the presence of an area of disturbed weather that could become Tropical Storm Harvey later this week.
The system, named Invest 91L, is a large and complex area of disturbed weather associated with a broad trough of low pressure and a tropical wave that is located to the south and southwest of the Cabo Verde Islands.
NHC forecasters believe that these systems will merge during the next day or two, and environmental conditions are then expected to be conducive for development of Invest 91L later this week while it moves westward at about 15 mph over the tropical Atlantic.
Invest 91L has a 60% chance of becoming a tropical cyclone by Saturday.
Invest 91L 2017 Spaghetti Models
Spaghetti models are in general agreement that the Invest 91L’s projected path will move in a west-northwestward direction towards the Caribbean through Saturday. However, it is too early for the computer models to make an accurate forecast as to where Invest 91L would make landfall along the U.S. east coast, if at all.
Most intensity computer models have Invest 91L reaching tropical storm strength by Thursday.
