As Hurricane Irma continues to roar across the Caribbean on a path toward Florida, a new tropical storm has formed in the Gulf of Mexico.

Tropical Storm Katia formed early Wednesday off the coast of Mexico.

The U.S. National Hurricane Center says Katia's maximum sustained winds are near 40 mph (65 kph) with some strengthening forecast over the next two days. But the hurricane center says Katia is expected to stay offshore through Friday morning.

The storm is centered about 105 miles (165 kilometers) east of Tampico, Mexico, and is moving east-southeast near 2 mph (4 kph).

The estimated minimum central pressure is 1006 mb.
