Isaias, which succeeded Tropical Depression Nine, would be the first hurricane of the belated Atlantic season
Tropical Storm Isaias formed early on Wednesday in the warm waters off eastern Mexico and forecasters said it was expected to strengthen into the first hurricane of the belated Atlantic season, as early as Thursday, before hitting the US Gulf coast later in the week.
Isaias succeeded Tropical Depression Nine as it strengthened overnight. It was located about 285 miles (460km) west of Progreso, Mexico, and about 580 miles south-west of where the Mississippi River spills into the Gulf of Mexico in Louisiana, according to the National Hurricane Center (NHC). The storm on Wednesday morning had maximum sustained winds of 40mph (65km/h) and was moving east to north-east at 8mph.
