noob question...but Beryl has been referred to thus far as sub-tropical...if it reaches hurricane strength is it automatically tropical, or would it be sub-tropical hurricane beryl?

The NHC removed the sub-tropical classification earlier today, it is now a fully tropical system at this point!

The 8 pm EDT advisory puts it at 60 kt and says any additional organization will make it a Cat 1. So, if the radar presentation improves in the next few hours, we have a hurricane. The center is still several hours offshore.

Shouldn't a hurricane warning be issued since it's so close to the threshold?

And one of those a possible hurricane in Beryl, its not even hurricane season yet and we have had a couple of good looking tropical storms

They both really came from the same upper trough that has sat off the East Coast, over Cuba, and into the Caribbean for weeks. Amazing.
