DISCUSSION AND 48-HOUR OUTLOOK
At 400 AM CDT (0900 UTC), the center of Tropical Storm Nate was
located near latitude 31.5 North, longitude 88.4 West. Nate is
moving toward the north-northeast near 23 mph (37 km/h). A turn
toward the northeast with an increase in forward speed is expected
during the next couple of days. On the forecast track, Nate's
center will continue to move inland across the Deep South, Tennessee
Valley, and central Appalachian Mountains through Monday.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Nate is expected to continue to quickly weaken as it moves
farther inland. It should degenerate into a remnant low late
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center. Mobile airport recently reported a wind gust of
54 mph (87 km/h).
The estimated minimum central pressure is 986 mb (29.12 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected to continue in the
tropical storm warning area for the next several hours.
STORM SURGE: 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 Pearl River to the Alabama/Florida border, including
Mobile Bay...5 to 8 ft
North of Pointe a la Hache to the mouth of the Pearl River...4 to 6
Alabama/Florida border to the Okaloosa/Walton County Line...3 to 5
Morgan City, Louisiana to Pointe a la Hache...1 to 3 ft
Okaloosa/Walton County Line to Indian Pass, Florida...2 to 3 ft
Indian Pass to Crystal River, Florida...1 to 3 ft
The deepest water will occur along the immediate coast near and to
the 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. For information
specific to your area, please see products issued by your local
National Weather Service forecast office.
RAINFALL: Nate is expected to produce the following rain
accumulations through Monday:
East of the Mississippi River from the central Gulf Coast into the
Deep South, eastern Tennessee Valley, and southern Appalachians:
3 to 6 inches, max 10 inches.
Across the Ohio Valley into the central Appalachians:
2 to 5 inches, max 7 inches.
TORNADOES: Isolated tornadoes are possible today, mainly from the
Florida Panhandle and eastern Alabama across western and northern
SURF: Swells generated by Nate will affect land areas around the
Gulf of Mexico through this evening. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
