New Tropical Depression Forms Below Gulf Of Mexico

A new tropical depression has formed in the southwestern Caribbean Sea — and it is expected to develop into a hurricane before possibly hitting the U.S. Gulf Coast late this weekend, the National Hurricane Center says.

The NHC issued its first public advisory about the storm, which has been dubbed Tropical Depression 16, on Wednesday. If the system develops as expected, it would be dubbed Nate — first as a tropical storm and later, if warranted, as a hurricane — according to the list of 2017 tropical cyclone names.

The federal hurricane center's current forecast track calls for the tropical cyclone to thread its way between Cancún, Mexico, and the western coast of Cuba to enter the Gulf of Mexico. Once in the Gulf, it could strengthen into a hurricane shortly before arriving at the U.S. mainland, possibly by around 8 a.m. ET Sunday.

"Residents along the Gulf Coast from Louisiana to Florida should monitor the progress of this system for the next several days," the National Hurricane Center cautions, "and heed any advice given by local officials."

The cyclone is expected to "bring tropical storm conditions and heavy rainfall to portions of Nicaragua and Honduras tonight through Thursday," the NHC warns. Parts of Central America could see flash floods, mudslides and rain of up to 30 inches in some places.

It's too early to know the precise level of threat the storm might pose to others in its path. Right now, its maximum sustained winds are only measured at around 35 mph. But over the next four days, its sustained winds are expected to strengthen to at least 80 mph.

Discussing the storm's likely growth, the hurricane center says:

"Rapid intensification is a possibility over the northwestern Caribbean or southern Gulf of Mexico while the system is traversing rather warm and deep waters, although it remains to be seen how separate the depression becomes from a larger gyre over Central America."

As for where the storm is heading, the NHC says it is likely to "move much faster to the north-northwest by Friday and northward into the Gulf of Mexico on Saturday."

After that, the hurricane center says, other factors should help steer the cyclone "to the north-northeast or northeast toward the northern Gulf states."

News of the developing cyclone comes after a series of hurricanes brought floodwaters and destruction, from Hurricane Harvey soaking Houston and nearby areas to Hurricane Irma blasting the Leeward Islands and Florida to Hurricane Maria hitting more islands before plowing through the center of Puerto Rico.

As member station WLRN reports from Miami, some 4,000 "hurricane evacuees from Puerto Rico and the U.S. Virgin Islands" arrived in Florida this week.
