BIRDSEYE VIEW POSTS

Since 2012 on the Weather Underground (www.wunderground.com) 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 via Disqus on Weather Underground at www.wunderground.com/cat6. You can see my Disqus feed at this link for my latest comments. Feel free to reply to me with your disqus account or e-mail at IOHurricanes@outlook.com

MY 2020 ATLANTIC HURRICANE SEASON BIRDSEYE VIEW POST #100A (Special Update)

...SUNDAY AUGUST 23 2020 11:45 PM EDT...

The following is a special update on Hurricane Marco. Recently Marco has been downgraded to a tropical storm due to effects of southwesterly shear...but it remains just below hurricane force with 70 mph maximum sustained winds. Recent satellite data (shown above) and surface fixes of the center from the National Hurricane Center shows Marco has tracked more northward and less westward while guided by the upper level southwesterly shearing winds. This means coastal storm surge...damaging wind...and heavy rain impacts will occur further east toward southeast Louisiana...southern Mississippi...and southern Alabama over the next several hours. This also greatly reduces Marcos impact potential for southwest Louisiana and southeast Texas.
