BIRDSEYE VIEW POSTS

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 IOHurricanes@outlook.com

MY 2021 ATLANTIC HURRICANE SEASON BIRDSEYE VIEW POST #24A (Special Update)

*******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 media...watches and warnings from your local weather office...and any evacuation orders issued by local governments to make the most informed and best decisions. Visit the NHC website hurricanes.gov (hurricanes dot gov) for the latest watches/warnings and official forecasts on active tropical cyclones.**********


...SATURDAY JUNE 19 2021 3:10 AM EDT...

The vigorous broad tropical low pressure in the northern Gulf of Mexico…designated potential tropical cyclone three…is making landfall on the Louisiana coast…it is not expected at this point to be upgraded to a named storm but currently is still producing tropical storm force conditions in its eastern rain bands:


**Parts of coastal southeastern Louisiana…coastal Alabama…and coastal Mississippi have seen gusty winds over the last several hours (as seen by the Boothville, LA; Gulfport, MS; and Mobile, AL National Weather Service station data). Isolated tree damage…power outages…etc…are possible.


**Based on the latest doppler radar…the heaviest rainfall with flash flooding potential had ended for SE Louisiana…and will not be reaching eastern Arkansas…due to the more east track this system has taken and also due to upper-level winds pushing the heaviest weather of this system down east. Watching for the spreading of heavy rain from now and thru this weekend across Mississippi… Alabama… Georgia… northwest Florida… Tennessee… Kentucky… West Virginia… Virginia…the Carolinas… Maryland… and Delaware. Should you encounter a flooded road…do not drive into the water or your vehicle could become stuck and you could drown.


**The remnants of this system have potential to redevelop over land and then along or just offshore the US east coast Sunday thru Tuesday either by tropical mechanisms… non-tropical mechanisms… or both. As such… gusty winds with isolated damage potential could occurr over eastern Tennessee… northwest Georgia… the Carolinas… Virginia… Maryland… and/or Delaware on Sunday and into Monday. Quickly passing coastal sea swells and rip currents as well as offshore choppy seas are a possibility Monday through Wednesday from the Carolinas through New England on the US Atlantic coast…and the Nova Scotia coast. The potentially strengthening remains of this system could impact Nova Scotia directly with wind on Wednesday depending on the exact track.


**For an in depth technical discussion on this system…refer to the area of interest #1 section of full update #24 found on the home page of this site.
