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 #45A (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.**********

Satellite image of Elsa’s remnant frontal cyclone as of 1340Z. The red X marks the center of circulation:

The remnant frontal cyclone of Elsa continues moving rapidly northeast and is currently centered between the east tip of Quebec and Newfoundland as of this writing. The vigorous frontal cyclone remains supported by the divergence zone of an upper trough to the west…producing an area of heavy rainfall north of the center currently over southern Labrador and an area of gusty winds southeast of the center (currently passing over Newfoundland) where the cyclonic circulation of the storm is aided by it’s fast northeast speed.


Here are some of the strongest Environment Canada (weather.gc.ca) station reports of wind (mph) generated by Elsa over the last several hours (value in kph kept in parenthesis):

**Fredericton NB…sustained 20 (33)…gust 34 (55) (02:00 local time)
