Dubbed "Hurricane Barry", a category 1 hurricane reaching up to 75 mph (120 km/h) winds made landfall around 1pm on Saturday and is sweeping across Louisiana.
As the storm began with overnight showers and significant winds, some motorists still managed to brave the weather in spite of warnings of 20 inches (50 centimetres) of rain.
Upon landfall, it was significantly weaker than expected and reduced to a tropical storm, but still resulted in flooding throughout the coast along the Gulf of Mexico.
Around 10 am, the storm was approximately 50 miles (80 km) away from the US coast.
Powerful winds toppling power lines, and 'life-threatening' flooding soon followed throughout the day.

The impact was first felt in Morgan City near New Orleans, among warnings of storms hitting cities on the coast followed by tornadoes in neighbouring Mississippi.
New Orleans airport also saw state-wide cancellations of all major flights in and out of the city on Saturday and has now reported that Barry will leave 2 ft (60 cm) of rain over the period of the next 2 days.
Barry is the first hurricane to hit the US mainland in 2019 during the Atlantic hurricane season. It is not, however, the first tropical storm of year, as Tropical Storm Andrea hit the Atlantic in May.
At least 1 hurricane has hit the US for 4 consecutive years and the Mississippi river has reached the highest point it has ever been during a storm of this size, as reported by ABC.
However, authorities have said that the Mississippi River is unlikely to flood over the levees protecting the city of New Orleans.
Ken Graham, the director of the National Hurricane Center, used Facebook Live to broadcast the storm, pointing to a large screen where a huge swirling mass of airborne water was projected while declaring that the storm was "off the chart".
The hurricane is currently moving at such a slow pace that a heavy downpour is likely to continue across Louisiana throughout the weekend.
He warned that "a lot of rain is on the way" as Barry gathers "a big slough of moisture" which was predicted to hit from Saturday morning and last until the afternoon.
He reminded broadcast viewers that "83 percent" of fatalities during a hurricane come from inland rain and advised people to stay off the roads.

Over 300 people ran to shelters upon the arrival of the hurricane, according to Marketa Garner-Walters, the secretary of the Louisiana Department of Children and Family Services.

While there have been no evacuations in New Orleans itself, an extra 10,000 people in low lying and flood-vulnerable areas were ordered to leave their homes by authorities.
Tourists and other party-goers did not let the warnings from Mayor LaToya Cantrell ruin their experience as they drank flood-cocktails on Bourbon Street on Friday night.
