Tropical Storm Hermine has the potential to inflict serious damage and “life-threatening” hazards to the Mid-Atlantic coast this Labor Day holiday weekend. Significant beach erosion, dangerous surf, damaging winds, torrential rain and major coastal flooding are all possible.

Bryan Norcross, hurricane specialist at the The Weather Channel, warned that Hermine could morph into a “freak-show storm.”

“The meteorology is simple enough,” Norcross wrote. “Over the Carolinas, Hermine will begin to get some of its energy from the jet stream, which has dipped down to yank it up the east coast. When it heads back over the ocean, it will be energized by both the warm water and the jet-stream winds. That means a strengthening storm will head north.”

He continued: “Then the freak show starts. That jet stream dip abandons the storm as it sits off the Delmarva or New Jersey coast over ocean water that is dramatically warmer then normal. So this huge orphan circulation sits and spins and pushes ocean water into the bays, sounds, and rivers in the Mid-Atlantic. And it does not let it out.”
