Shortly after the 10 p.m. advisory, The National Hurricane Center upgraded Nate to a hurricane with estimated maximum winds of 75 miles per hour.
The track pictured above was issued with the 10 p.m. advisory when Nate was still at tropical storm strength.
Nate continues to move quickly north-northwest at 22 miles per hour, putting it about 500 miles south-southeast of the mouth of the Mississippi River.
The National Hurricane Center says Nate is an "asymmetric storm, with most of the winds located on the eastern side of the circulation, and this structure is likely to continue until landfall due to the cyclone's fast forward speed. Therefore, locations to the east of where Nate makes landfall are expected to receive significantly stronger winds than locations to the west of the center. Regardless, there is still too much uncertainty to know exactly where landfall will occur, and all locations within the hurricane warning area should be preparing for hurricane-force winds."
The NHC also warned that rapid intensification could not be ruled out.
"Nate will bring heavy rainfall of 3 to 6 inches with isolated totals of 10 inches east of the Mississippi River from the central Gulf Coast into the Deep South, eastern Tennessee Valley, and southern Appalachians through Monday, resulting in the the potential for flash flooding in these areas," read the tropical weather discussion.
