Yes it was, here's a bit of History for you. --

Hurricane Danny (1985) - Used for the first time, was a replacement for David (1979) - The Danny was a 90 mph Category-1 that made landfall along the Gulf Coast at Peak Intensity.

Tropical Storm Danny (1991) - Was a Moderate Tropical Storm West of the Cape Verde Islands, didn't seem to cause much Effects anywhere.

Hurricane Danny (1997) - Was an 80 mph Category-1 Hurricane that, like the 1985 Version of it, made landfall along the US Gulf Coast

Hurricane Danny (2003) - Was a 75 mph Category-1 that had a rather high pressure and also had a rather odd track in the Atlantic that may have allowed some effects in Bermuda

Tropical Storm Danny (2009) - A Strong Tropical Storm that May have had some Effects along the US East Coast

Hurricane Danny (2015) - And this is obviously the Current one, A rather Small Tropical Cyclone that Strengthened a rather Unexpected Amount and saw Major Hurricane Status for the First time as Hurricane Hunters were able to give it a Peak of 115 mph.. -

So yes, this was it's first time as a Major Hurricane (Category-3 or Greater)
