GFS and Euro Model Disagree on Tropical Storm Sam’s Track

On Thursday morning, Tropical Storm Sam developed in the Atlantic Ocean, becoming the 18th named storm of the 2021 Atlantic Hurricane Season. 

The latest forecasts predict that Sam will become a hurricane Friday evening or Saturday and develop into a major hurricane early next week. 

This storm should be monitored as a potential threat to the U.S. mainland next week but could also take a northward turn that keeps it off the East Coast. 

However, there’s some model disagreement on how close Sam will actually come to threatening the U.S. mainland. The Euro model suggests a potential Bahamas landfall and East Coast approach. On the other hand, the Global Forecast System (GFS) suggests Sam will remain offshore the entire cycle, not threatening the Bahamas. 

As the 2021 Atlantic Hurricane Season continues, let’s take a look at storms that have occurred and what names are next on the list.
