HOLT, Fla., Sept. 17, 2019—Two new tropical depressions joined Hurricane Humberto today.

Tropical Depression Ten was announced at the National Hurricane Center’s 11 a.m. tropics update.

And now-Tropical Storm Imelda, in the Gulf of Mexico, was announced by a NHC special advisory at 12:45 p.m.

Imelda is the ninth-named storm of the 2019 hurricane season.

The storm became a tropical system by noon today over the Gulf of Mexico just off the Texas coast before quickly strengthening to a tropical storm.

Some additional strengthening is possible before it moves inland over the upper Texas coast later today, according to the NHC.

Tropical Depression Ten

Tropical Depression Ten, located west of the Lesser Antilles, is moving at a fast clip of 12 mph and is forecast to approach the northern Leeward Islands Thursday night or Friday.

Strengthening is forecast during the next couple of days and the depression is expected to become Tropical Storm Jerry later today, according to the NHC.

Jerry is expected to become a hurricane by the time the storm approaches the northern Leeward Island within the next 72 hours.

The NHC is also forecasting a tropical wave to enter the Atlantic off the west coast of Africa Thursday.

Some gradual development is possible as the system moves generally westward over the tropical Atlantic during the weekend.

For now, the NHC is giving it a 20 percent chance of development.
