There is a high likelihood of a life-threatening storm surge. In some spots, the surge will reach 9' above sea level. See map below.
The forecast landfall position has not changed this evening. See map below.
Winds of more than 70 mph, with gusts to 95-100 mph, are likely parts of or all of the Mississippi and Alabama coasts. Please see suggested safety preparations below and rush them to completion tomorrow. If you are in an evacuation area, please evacuate.
Finally here is the 9:45pm satellite image of Nate. You'll have sometime to compare it with in the morning.
UPDATE: 10:10PM. Pressure is dropping and is now 990mb. It appears from Hurricane Hunter data that Nate is now a hurricane but I'll let the Hurricane Center make the official call.
