Tropical Storm Gordon is set to slam into the north central Gulf Coast on Tuesday night.
Gordon is expected to produce total rain accumulations of four to eight inches over the western Florida Panhandle, southwest Alabama, southern and central MS, southeastern and northeastern Louisiana, and southeast Arkansas, the NHC said.
Hurricane Warnings and Tropical Storm Warnings have been issued for parts of the Louisiana, Mississippi, Alabama, and Florida coasts.
Hurricane warnings stretch from the Florida/Alabama border to the Louisiana/Mississippi border as the storm center is most likely to strike along the Mississippi or Alabama coastline.
This storm is now about 700 miles west northwest of the Cape Verde Islands with sustained winds of 50 mph. In addition to Gordon, Tropical Storm Florence is hovering over the eastern Atlantic but is not expected to make landfall.
The Mississippi cities of Gulfport, Biloxi and Long Beach ordered mandatory evacuations of their harbors and marinas, and the U.S. Coast Guard said the ports of New Orleans and of Gulfport and Pascagoula in Mississippi could have to be closed if winds get too strong.
Gordon is expected to continue to move in a generally west-northwest motion until it makes landfall somewhere on the central Gulf Coast as a strong tropical storm.
The National Weather Service said conditions were "possible" for tornadoes in the affected parts of South Florida on Monday night.
Tropical-storm-force winds extend outward up to 60 miles per hour (95 km) from the center of the storm.
In anticipation of heavy rains, the Flood Protection Authority-East (FPA) has closed 21 floodgates on the Lake Borgne Surge Barrier near New Orleans, according to a press release. The region could see rising waters of 3 to 5 feet.
A storm surge covered barrier islands as the storm blew through, and some inland roadways were flooded by the rain.
The Governor is warning residents to take caution. Its projected path moved further east on Monday, putting MS and Alabama under a hurricane warning.
The warning is related to potential Tropical Cyclone 7 which, if it organizes into a tropical storm, will become Tropical Storm Gordon.
At least 300 people were displaced in Riley County, Kansas, after the area was struck by heavy rain and significant flooding.
Gordon is the seventh named tropical storm or hurricane to form in the Atlantic basin this year.
Alert Day Wednesday: continued tropical storm conditions with widespread rain and a chance for thunderstorms.
