DISCUSSION AND OUTLOOK
At 100 AM CDT (0600 UTC), the center of Tropical Storm Zeta was
located near latitude 32.9 North, longitude 87.4 West. Zeta is
moving quickly toward the northeast near 31 mph (50 km/h). An even
faster northeastward motion is expected later today, followed by a
rapid east-northeastward motion tonight and Friday. On the forecast
track, the center of Zeta will move across portions of the
southeastern U.S. this morning, across the Mid-Atlantic states this
afternoon, and emerge over the western Atlantic by tonight.
Maximum sustained winds have decreased to near 70 mph (110 km/h)
with higher gusts. Additional weakening is expected, and Zeta
should decay into a non-tropical gale-force low later today. The
low should become absorbed by a frontal system over the western
Atlantic on Friday.
Tropical-storm-force winds extend outward up to 150 miles (240 km).
An observation in Wetumpka, Alabama, recently reported sustained
winds of 44 mph (71 km/h).
The estimated minimum central pressure based on surface
observations is 985 mb (29.09 inches).

STORM SURGE: Along the northern Gulf Coast, 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 could reach the following heights above ground
somewhere in the indicated areas if the peak surge occurs at the
time of high tide…
MS/AL to AL/FL border including Mobile Bay…3-5 ft
Mouth of the Atchafalaya River to AL boarder including Lake
Maurepas, Lake Pontchartrain, and Lake Borgne …1-3 ft
AL/FL Boarder to Yankeetown FL including Pensacola Bay,
Choctawhatchee Bay and Saint Andrew Bay…1-3 ft
The deepest water will occur along the immediate coast near and to
the right 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.
WIND: Tropical storm conditions are expected to continue within
the warning area near the northern Gulf Coast during the next few
Damaging winds, especially in gusts, are spreading well inland
across portions of central and northern Alabama, and northern
Georgia, and these winds will shift into the Carolinas and
southeastern Virginia later today. Wind gusts could be especially
severe across the southern Appalachian Mountains.
RAINFALL: Areas of heavy rainfall, both in advance of Zeta and
along the track of Zeta, will impact areas from the central Gulf
Coast to the Mid-Mississippi and Ohio Valleys, and east into the
southern to central Appalachians and Mid-Atlantic today.
Rainfall totals of 2 to 4 inches with isolated amounts of 6 inches
are expected across these areas, resulting in flash, urban, small
stream, and minor river flooding.
TORNADOES: A few tornadoes are possible over parts of southern
Alabama and the western Panhandle of Florida during the next few
hours. An isolated tornado or two is possible later today across
much of the Carolinas and southern Virginia.
