DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Post-Tropical Cyclone Zeta
was located near latitude 38.8 North, longitude 75.3 West.  Zeta is 
moving toward the east-northeast near 55 mph (89 km/h), and this 
general motion is expected to continue through tonight.  On the 
forecast track, the center of Zeta will emerge over the western 
Atlantic this evening.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Some strengthening is forecast tonight, but the cyclone should 
become absorbed by a frontal system on Friday.
 
Tropical-storm-force winds extend outward up to 310 miles (500 km)
mainly to the southeast of the center.  A sustained wind of 39 mph 
(63 km/h) and a gust to 46 mph (74 km/h) were recently reported at 
Ocean City, Maryland.
 
The estimated minimum central pressure is 992 mb (29.30 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Zeta can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and
on the web at www.hurricanes.gov/text/MIATCDAT3.shtml.
 
WIND:  A few strong gusts are still possible across portions of
extreme eastern North Carolina, southeastern Virginia, and the
southern Delmarva Peninsula during the next couple of hours.
 
RAINFALL:  The last of the heavy rainfall along the track of Zeta 
will impact the Mid-Atlantic through this evening.  Additional 
rainfall totals of an inch or less are expected across these areas, 
possibly resulting in flash, urban, small stream, and isolated minor 
river flooding.

Post-Tropical Cyclone Zeta Discussion Number  21
NWS National Hurricane Center Miami FL       AL282020
500 PM EDT Thu Oct 29 2020
 
Zeta lost tropical characteristics and was declared post-tropical a
few hours ago.  The surface pressure field has become elongated
with the center now embedded within a frontal zone over the
Mid-Atlantic states.  The maximum sustained winds are still
estimated to be 45 kt, based on an observation received from
northeastern North Carolina a few hours ago, and winds have been
increasing at marine sites located just off the Mid-Atlantic coast.
 
Zeta is zooming toward the east-northeast (060/48 kt), and its
center is just about to move off the Delmarva Peninsula over the
western Atlantic waters.  This motion should continue for the next
day or so since Zeta is embedded within fast westerly flow ahead of
a strong mid-level trough.
 
Some baroclinic re-intensification is expected over the next day or
so while Zeta moves farther out over the western Atlantic, and the
12-hour forecast intensity is based on the GFS and ECMWF global
models.  Zeta’s center is expected to dissipate within the frontal
zone by 24 hours, with another strong low pressure area likely to
develop and move toward the north Atlantic over the next several
days.  The forecast wind radii are based on guidance from the
Ocean Prediction Center.
 
This is the last advisory issued on Zeta.  Additional information
on this system can be found in High Seas Forecasts issued by the
National Weather Service, under AWIPS header NFDHSFAT1, WMO header
FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php
 
 
KEY MESSAGES:
 
1.  Strong wind gusts are still possible over portions of extreme
eastern North Carolina, southeastern Virginia, and the southern
Delmarva Peninsula during the next couple of hours.
 
2.  Through this evening, the last of the heavy rainfall along the 
track of Zeta is expected over the Mid-Atlantic. This rainfall may 
lead to flash, urban, small stream, and isolated minor river 
flooding.
