2012 Atlantic Hurricane Season Birdseye Discussion #137A (Special Update)

By: NCHurricane2009 , 10:10 PM GMT on October 19, 2012

...FRIDAY OCTOBER 19 2012...6:10 PM EDT...
Two Atlantic tropical cyclones are possible this upcoming week...

In addition to potential Caribbean tropical cyclone formation discussed in paragraph P5 of discussion #137...their is also potential for tropical cyclone formation in the central open Atlantic in association with a tropical wave interacting with an upper vortex (paragraph P6 of discussion #137). Although I had seen computer model support for a central open Atlantic tropical cyclone as of the previous discussion...I had not mentioned it as I was not sure which system the models were picking up on.

Both the Caribbean disturbance and the open Atlantic disturbance have been introduced into the National Hurricane Center Tropical Weather Outlook. I will be assessing whether or not I believe either of these areas have a high risk of eventual tropical cyclone formation. If I believe so...I could be introducing either or both as special features in my next full blog update. In the meantime...return to full discussion #137 for an assessment on the rest of the Atlantic tropics.
