A tropical depression has formed in the Atlantic and could pose an issue for parts of the Caribbean and potentially the U.S.
If the storm does strengthen, it would be called Sam. The only remaining names on the list for the 2021 Atlantic hurricane season are Sam, Teresa, Victor, and Wanda.
If those names are used, there is a supplemental list approved by the World Meteorological Organization which replaced the Greek alphabet used during last year’s record-breaking season.
Two other storms are swirling in the Atlantic: Tropical Depression Rose and Tropical Depression Peter, which dissipated late Wednesday.
Both are not forecast to make landfall, but the remnants of Peter could produce rainfall totals of 1 to 4 inches, with storm total accumulations up to 6 inches, across parts of the Northern Leeward Islands, and areas in the Virgin Islands, Puerto Rico and Hispaniola through Thursday morning.
