Tropical Depression Seven strengthened into Tropical Storm Gonzalo on Wednesday, according to the National Hurricane Center. Earlier this afternoon, the storm was about 1,110 miles east of the southern Windward Islands, packing winds of 50 mph and moving to the west at 14 mph.

International weather experts say given the increased organization of the system and its small size, Gonzalo’s (pronounced gohn-SAH-loh) likelihood of becoming a hurricane, is rising. Strengthening will continue in the next day as the storm is expected to become the season’s first hurricane by Thursday.

The National Hurricane Center is forecasting the storm to weaken slightly before moving over the Windward Islands. The storm may even fizzle after it moves over the islands, as many models are indicating, or it could continue to intensify into next week.
