Forecast Track: Nate is expected to turn due north later today, and will continue on that trajectory until landfall, which will likely be between Biloxi, Mississippi and Mobile Alabama. However, there is still some time for minor shifts/wobbles east or west, and a landfall in Southeast Louisiana or just east of or in Mobile can’t be ruled out.
After landfall tonight, Nate will accelerate north, and then north-northeast, across the Southeast and into the Mid-Atlantic tomorrow afternoon into Monday.
Intensity Forecast: Nate will continue to intensify up until landfall, as environmental conditions will remain conducive for intensification, and Nate will likely be a high-end category 1 or low-end category 2 at landfall. Nate will then weaken while progressing inland after landfall.
Timing: Impacts from Nate will begin to be felt as early as this afternoon and early this evening, increasing in severity thereafter. However, Nate is a fast moving system, and conditions should improve across much of the North-Central Gulf Coast starting tomorrow afternoon.
Impacts:
- Hurricane-force winds, 5 – 9′ of surge, and 6 – 8″ of rainfall will occur in the hurricane warning area.
- Tropical-storm-force winds, hurricane-force wind gusts, 4 – 6′ of surge, and 4 – 6″ of rainfall will occur in the tropical storm warning area and hurricane watch area.
- Tropical-storm-force wind gusts, 1 – 2″ of rainfall, and 1 – 3′ of surge will occur in the tropical storm watch area.
It should also be noted that widespread power outages are likely, along with isolated, brief tornadoes across Southern Mississippi, Southern Alabama, and the Western Florida Panhandle.
If you are in the hurricane warning area, all preparations for Nate should be rushed to completion, and done by early this evening at the absolute latest.
