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 2021 ATLANTIC HURRICANE SEASON BIRDSEYE VIEW POST #25A (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.

...SUNDAY JUNE 20 2021 1:28 PM EDT...

Satellite image of Tropical Depression Claudette as of 1700Z:

The following an update on Tropical Depression Claudette’s impact potential:


**The latest weather station observations suggest an end to breezy conditions across Alabama and Georgia…while breezy conditions have spread across South Carolina including the coast…and southeastern inland North Carolina and will soon reach the coast here. These breezy conditions will only produce very isolated damage if any. Coastal northeast South Carolina and coastal southeastern North Carolina south of Cape Hatteras are more likely to see the formation of a tropical storm wind field tonight which will have a little more damage potential…but damage will still tend to be isolated.

**Quickly passing coastal sea swells and rip currents as well as offshore choppy seas are likely Monday through Tuesday from the Carolinas through New England on the US Atlantic coast…and the Nova Scotia coast. Based on the outlook from full post #25…the chances for Claudette to kick up the seas on coastal Newfoundland is low due to forecast weakening….and also the chance for Claudette to bring winds directly to Newfoundland and Nova Scotia is low.

**Based on the latest doppler radar…thru the remainder of today the area of heavy rainfall with flash flooding potential is narrowed down to eastern Georgia…the Carolinas… and southeast Virginia…although the thunderstorm and rainfall intensity has reduced today which makes the risk of flash flooding more isolated. But in the event you do encounter a flooded road…do not drive into the water or your vehicle could become stuck and you could drown.

**The surface southerly flow on the east side of Claudette combined with upper westerly winds over the SE US is producing shear favoring tornadoes. It would not surprise me if a tornado watch is issued in NE South Carolina and SE North Carolina later today.

**For an in depth technical discussion on Claudette…refer to full update #25 found on the home page of this site.
