The National Hurricane Center said Wednesday a tropical wave in the eastern Atlantic Ocean is now Tropical Storm Irma.
Advisories will begin at 11 a.m.
The wave is located just west of the Cabo Verde islands moving west, northwest to westward at 15 mph.
The storm is forecast to move through the tropical Atlantic this week into next. Most of the latest model runs curve Irma into the open waters of the Atlantic.
However, previous model runs had Irma near the greater Antilles islands late next week.
NHC will be initiating advisories at 11 AM AST on Tropical Storm Irma, located west of the Cabo Verde Islands.
