President Donald Trump issued an executive order to rename the Gulf of Mexico. It is not yet policy for the National Weather Service and other government agencies to use the new term, “Gulf of America,” and other forecasts from the agency’s meteorologists across the country have continued to mention the Gulf of Mexico, if not, simply, the gulf.

And yet it could soon be commonplace in weather forecasts and other official government communications. Under Trump’s order, the U.S. Department of Interior is expected to add the term to the database of geographic names soon— “and remove all references to the Gulf of Mexico.” Once that happens, agencies including the Weather Service will be expected to abide by the change.

This is not the first case of one country questioning why a body of water bears the name of another country, says Mark Monmonier, Distinguished Professor Emeritus of Geography and the Environment: North and South Korea have been in dispute with Japan over the naming of the Sea of Japan/East Sea since the 1990s. In a similar debate, Iran has sought to rename the Persian Gulf to the Gulf of Iran.

But given how long-standing the Gulf of Mexico name has been, Monmonier says he doesn’t see a logical reason to change it.
