The National Hurricane Center says Zeta is now a hurricane.
"Data from an Air Force Reserve Hurricane Hunter aircraft indicate that Zeta has become a hurricane, with maximum sustained winds near 80 mph with higher gusts."
The forecast calls for Zeta to hit the Yucatan Peninsula, then enter the Gulf and get stronger.
"Zeta is forecast to strengthen again while it moves over the southern Gulf of Mexico later on Tuesday."
The Hurricane Center says landfall is expected Wednesday afternoon or evening somewhere between Southeast Louisiana and Florida.
"Heavy rains will begin to impact the central Gulf Coast Tuesday night, spreading inland across eastern Mississippi, Alabama, northern Georgia during Wednesday."
Hurricane force winds are also possible, knocking out power and pushing water ashore.
