SUMMARY OF 400 AM EST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...33.3N 76.8W ABOUT 85 MI...135 KM SE OF WILMINGTON NORTH CAROLINA MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...ENE OR 60 DEGREES AT 21 MPH...33 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 400 AM EST (0900 UTC), the center of Post-Tropical Cyclone Eta was located near latitude 33.3 North, longitude 76.8 West. The post-tropical cyclone is moving toward the east-northeast 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 non-tropical cyclone during the next day or so before it becomes absorbed by a larger non-tropical cyclone on Saturday or Saturday night. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Eta will affect portions of the southeastern United States coast today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

000 WTNT44 KNHC 130834 TCDAT4 Post-Tropical Cyclone Eta Discussion Number 52 NWS National Hurricane Center Miami FL AL292020 400 AM EST Fri Nov 13 2020 While 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.
