Carlos is the third Hurricane of the Pacific season in 2015.

Meanwhile, on Mexico's east coast, a cluster of thunderstorms over the Yucatan Peninsula has a 60% chance of developing into a hurricane in the next few days according to the US National Hurricane Center.

That tropical storm threatens to bring flooding to eastern Mexican states as well as parts of the southern US including Texas which were devastated by recent flooding in which at least 31 died.

If the storm does become a hurricane it will be named Bill, becoming the second hurricane of the 2015 Atlantic season.

"We have a very serious flood threat that will be occurring across Texas," said AccuWeather meteorologist Evan Duffy. "The big area of concern is Houston, where there are still flood gauges showing major and moderate flooding."
