000 WTNT33 KNHC 292036 TCPAT3 BULLETIN Post-Tropical Cyclone Zeta Advisory Number 21 NWS National Hurricane Center Miami FL AL282020 500 PM EDT Thu Oct 29 2020 ...ZETA ZOOMING OFFSHORE THE MID-ATLANTIC COAST TOWARD THE WESTERN ATLANTIC... ...THIS IS THE LAST ADVISORY... SUMMARY OF 500 PM EDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...38.8N 75.3W ABOUT 25 MI...35 KM WSW OF CAPE MAY NEW JERSEY MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...ENE OR 60 DEGREES AT 55 MPH...89 KM/H MINIMUM CENTRAL PRESSURE...992 MB...29.30 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. 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. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.

000 WTNT43 KNHC 292037 TCDAT3 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.
