Why are they calling the offshore gulf coast storm a potential tropical cyclone? Why isn’t it a potential hurricane? I thought cyclones were in the Pacific/South Pacific and hurricanes were in the Atlantic.
Cyclone is a common term. I suppose they could have deemed it a potential tropical storm In Aussie and India they are exclusively called cyclones. NHC is not calling it a PH ( potential hurricane ) because they don’t anticipate that potential.
Cyclone simply refers to any large scale circulation around a low pressure system. It can occur over both water and land any time of year. In the N hemisphere it would rotate counter-clockwise and the opposite in the S hemisphere.
Yes we’re using cyclone in the generic sense – as a potential tropical cyclone could develop into a tropical depression, tropical storm and/or hurricane. This is simply a way to designate that while a system isn’t impacting places at the moment, we expect it to strengthen and become a threat to land.
