Hurricane Nate began as a tropical depression over the northwest Caribbean Sea on the morning of October 4th and moved fairly rapidly northward, with forward speeds in excess of 20 mph, for the next several days while gaining strength. The storm moved north-northwestward through much of the day on the 7th, as it approached southeast Louisiana before turning northward.
Two landfalls occurred in the CWA. The first was near the mouth of the Mississippi River at 7 pm CDT as a Category 1 hurricane. The second landfall was near Biloxi, Mississippi at 1230 am CDT October 8th, also as a Category 1 hurricane. As the hurricane approached southeast Louisiana and coastal Mississippi, it became asymmetric with much of shower and thunderstorm activity along with the stronger winds primarily on the east side of the system.  The storm continued moving rapidly to the north and north-northeast, and had weakened to a tropical depression near Birmingham, Alabama by 10 am CDT on the 8th.
Minor impacts due to storm surge flooding were noted over several parishes in southeast Louisiana, while moderate impacts due to strong winds and storm surge were noted over the Mississippi coastal counties.

Minor to moderate impacts were noted from storm surge.
