Satellite images and tracking maps of Category 4 Major Hurricane Eta 2020, October 29 - November 13. Max wind speed 150mph.
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 knots 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 knots. Eta is forecast to strengthen as a baroclinic low until the system is absorbed by another low pressure area in about 48 hours.
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.
