Since 2012 on the now retired Weather Underground blogs, I have been posting annotated "birdseye view" charts of the Atlantic basin, with a detailed explanation and forecasting that references the chart. From there you may know me as "NCHurricane2009." While I now do these "birdseye view" posts here, I will continue to do comments at Yale Climate Connections via Disqus where the former Weather Underground community has moved to. Feel free to reply to me there, at my Disqus feed at this link, or via e-mail at

******Note that forecasts and outlooks in this post are NOT the official forecast from the National Hurricane Center (NHC). They are my own detailed views on the Atlantic tropics based on current observations and latest computer model runs. As such do not make decisions based on my posts...consult news and warnings from your local weather office...and any evacuation orders issued by local governments to make the most informed and best decisions.

...SUNDAY OCTOBER 25 2020 11:30 PM EDT...

Satellite image of Tropical Storm Zeta as of 0310Z:

Zeta already reaching strong tropical storm strength while becoming well organized...chances for hurricane force conditions in Quintana Roo in the northeastern Yucatan Peninsula of Mexico are very high and preparations for such conditions should be completed within the next 24 hours. This special update is to increase my intensity forecast for Zeta as outlined below. I have also nudged my forecast track eastward as Zeta has been stalled instead of moving by the time the incoming front from the central US intersects Zeta and bends the track northeast Zeta will more likely be further east. Weakening is still shown after 48 hours as the upper trough of the incoming frontal system will be likely imparting increasing wind shear. As Zeta system merges with the front and becomes supported by the eastern divergence zone of the upper will transition into a non-tropical remnant frontal cyclone as it makes landfall along the eastern US Gulf coast. Even as it becomes less tropical...Zeta will have potential for high winds and coastal storm surge as it will only slowly weaken due to the support of the upper trough.
