The category 2 storm is expected to bring heavy rains and damaging winds to the state which has been bombarded with another hurricane this season. Zeta is the second storm to strike the state this year.
Philip Klotzbach, a research scientists at Colorado State University, said the prior record of four was set in 2002.
The hurricane made landfall near Cocodrie and was about 65 miles south-southwest of New Orleans today, according to New York Times.
It is reported the storm was moving at a staggering 24 miles per hour with maximum sustained winds of 110mph.
Earlier today, a hurricane warning was issued along the coast of Morgan City to the Mississippi-Alabama order as well as the metropolitan New Orleans area.
Louisiana Governor, John Bel Edwards, issued a state of emergency on Tuesday and said President Donald Trump had approved the request.
He tweeted: “Tonight, we learned that @POTUS approved our request for a Federal Emergency Declaration as Hurricane Zeta heads towards Louisiana.
“We are grateful for the incredibly fast response.
“Though we don’t know exactly what Zeta will bring, we know this will be a big help in the recovery process for those communities that will feel its impact.”
The hurricane was expected to make a second landfall along the Mississippi coast tonight and then move towards the south-eastern and eastern US.
Up to six inches of rain is expected to fall in some locations.
Officials in New Orleans sent warnings to residents to take precautions in anticipation of the storm.
At around 2am this morning, the Lower Mississippi River and the Port of New Orleans were both closed to ships and vessels.
The hurricane hit the northern Yucatan Peninsula of Mexico at the start of this week.
This mark the eleventh hurricane and 27th named storm in an Atlantic cyclone season.
Forecasters have resort to using Greek letters as they have run through the alphabet of names during the hurricane season.
Environmentalists have warned the Category 2 hurricane could have a detrimental impact on the migratory songbirds.
Erik Johnson, director of bird conservation with Audubon Louisiana, said: “A storm could be devastating for a migratory songbird that fuels up just enough to make it across the Gulf.”
In other areas, rising storm waters can bring alligators closer to pathways and buildings.
Dave Barak, a National Park Service park ranger said: “Once the alligators go back home, we open back up.”
As the storm hit this week, climate scientists said the series of storms in Louisiana could be simply blamed on bad luck rather than climate change.
James P. Kossin, a researchers with the National Oceanic and Atmospheric Administration, said: “It’s kind of like flipping a coin and getting heads five times in a row – it happens.”
He added it is not “surprising” given the size of the Mexican Gun and the random weather factors.
