Cyclone II is a son of Pryor's Sea Breeze and is either a son of Nightmist or Nightstorm. DNA testing has shown that he probably isn't a son of Nightmist. Cyclone II was born on Mike Pryor's farm in Pennsylvania and was sold to Stag Creek Farm in Texas as a young horse. Cyclone II sired three foals in 2011. The Texas born ponies are black pinto gelding Firefly Mist out of Sea Stormy Fly, bay pinto gelding Moontide Mist out of Rolling Bay Sugar Pixie, and bay pinto filly Sea Star Mist out of Sweet Breeze of Chincoteague. He bred Heart of the Bay while in Texas and afterwards she was sold to Pennsylvania and foaled 2012 bay pinto mare Winter Moon. Winter Moon was later sold to the Chincoteague Volunteer Fire Company and has lived feral on Assateague since 2018. His granddaughters out of Winter Moon that have lived on Assateague are CLG Maureen's Misty Moon, SCC Misty's Hailstorm, and Rylee's Way.
