Post-Tropical Cyclone Eta Forecast Discussion Number 52
2020-11-13 09:34:37| National Hurricane Center (Atlantic)
Issued at 400 AM EST Fri Nov 13 2020 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.
