A waterspout was confirmed off the coast of Alabama as Hurricane Nate approached Saturday afternoon, according to the National Weather Service in Mobile/Pensacola.
Videos posted to Twitter show appeared to show the waterspout stretching down from the clouds over the water near Orange Beach.
This would make it a tornadic waterspout versus a fairweather waterspout. Tornadic waterspouts "are tornadoes that form over water, or move from land to water," according the National Oceanic Service. "They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning."
NWS Mobile said that the waterspout could move onshore and said that a tornado warning had been issued locally.
The National Hurricane Center says that a couple of tornadoes "will be possible beginning late this afternoon over parts of the central Gulf Coast region."
Hurricane Nate, which is currently a Category 1 storm, is expected to make landfall somewhere between Louisiana and the Florida panhandle Saturday evening as a Category 2 storm.
Some rain bands associated with the storm have already moved ashore.
