There are no coastal watches or warnings in effect.

SURF: Swells generated by Eta will affect portions of the southeastern United States coast today. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 400 AM EST (0900 UTC), the center of PostTropical Cyclone Eta was located near latitude 33.3 North, longitude 76.8 West. The posttropical cyclone is moving toward the eastnortheast near 21 mph (33 km/h) and this motion is expected to continue with an increase in forward speed through Saturday. On the forecast track, Eta is expected to gradually pull away from the southeast U.S. coast today. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Eta could intensify a little as an nontropical cyclone during the next day or so before it becomes absorbed by a larger nontropical cyclone on Saturday or Saturday night. Tropicalstormforce winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches).

the cyclone is still generating a cluster of strong convection to the northeast of the center, satellite imagery, surface observations and scatterometer data indicate that Eta has merged with a baroclinic zone and become an extratropical cyclone off the southeastern coast of the United States. The scatterometer data showed vectors of 40-50 kt along a front or convergence zone northeast of the center, but these vectors were in the strong convective region and their reliability is uncertain. This, the initial intensity is held at a possibly conservative 40 kt. Eta is forecast to strengthen as a baroclinic low until the system is absorbed by another low pressure area in about 48 h. The initial motion is 060/18. The post-tropical cyclone cyclone should continue this general motion with an increase in forward speed until it is absorbed.

This is the last advisory issued by the National Hurricane Center on Eta. 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
