Late Morning Update On Hurricane Nate

| October 7, 2017 @ 10:07 am

**Nate is now expected to be a category two hurricane at the time of landfall tonight on the Gulf Coast**

At 1000 AM CDT, the center of Hurricane Nate was located near latitude 26.6 North, longitude 88.4 West. Nate is moving rapidly toward the north-northwest near 26 mph, and this general motion is expected to continue through this evening. A turn toward the north is forecast tonight, followed by a turn toward the
northeast. On the forecast track, the center of Nate will move across the northern Gulf of Mexico today and will make landfall along the central U.S. Gulf Coast tonight.

Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 90 mph with higher gusts. Additional strengthening is expected before landfall, and Nate is forecast to be a category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale when the center reaches the Gulf Coast.

Hurricane-force winds extend outward up to 35 miles, primarily to the east of the center and tropical-storm-force winds extend outward up to 125 miles. The minimum central pressure estimated from the Hurricane Hunter aircraft data is 984 mb (29.06 inches).

A Tropical Storm Warning has been issued for inland Alabama as far north as Tuscaloosa, Birmingham, Pell City, and Talladega…

GULF COAST: Conditions will deteriorate on the Central Gulf Coast this afternoon, with increasing wind and rain. The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water is expected to reach the following heights above ground if the peak surge occurs at the time of high tide…

Mouth of the Mississippi River to the Mississippi/Alabama border…7 to 11 ft
Mississippi/Alabama border to the Alabama/Florida border, including Mobile Bay…6 to 9 ft
Morgan City, Louisiana to the mouth of the Mississippi River…4 to 6 ft
Alabama/Florida border to the Okaloosa/Walton County Line…4 to 6 ft
Okaloosa/Walton County Line to Indian Pass, Florida…2 to 4 ft
Indian Pass to Crystal River, Florida…1 to 3 ft

The deepest water will occur along the immediate coast near and tothe east of the landfall location, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

In addition to storm surge issues, rain amounts on the Gulf Coast will be in the 3 to 6 inch range, and a few tornadoes are possible as well.

The City of Gulf Shores, in conjunction with the City of Orange Beach, will enforce a mandatory curfew beginning at 8:00 tonight through 6 a.m. tomorrow. This curfew is in place for the safety of citizens due to expected hurricane-force winds during this time. All vehicles should stay off of roadways until the curfew has expired. Local businesses are asked to prepare and adjust for proper closing times to allow for employees to return home safely before the curfew begins.

Conditions will improve on the coast tomorrow as Nate moves to the north.

NORTH/CENTRAL ALABAMA: The sky will be mostly cloudy this afternoon, but we only expect a few scattered showers. Wind and rain will increase after midnight tonight and during the day tomorrow. Sustained winds will ramp up into the 30-50 mph range tomorrow, with potential for higher gusts on ridges. This will be sufficient for tree damage and power outages…

Rain amounts of 2-4″ are likely, with potential for locally higher amounts. A flash flood watch has been issued for much of Central and Northeast Alabama.

And, a few isolated tornadoes are possible tomorrow, generally east and south of a line from Linden to Alabaster to Talladega to Wedowee.

Wind and rain will slowly diminish tomorrow night.
