US: Massive Shelf Cloud Looms Over Myrtle Beach Waterpark.

Myrtle Beach, United States - June 14, 2026 Video filmed by X user Liam’s Weather (Student Meteorologist Liam Kenny) shows a massive, dark shelf cloud dominating the sky above Myrtle Waves WaterPark, with its leading edge stretching low and threateningly across the horizon. The cloud's textured gray underside stands in sharp contrast to lighter patches of sky around its edges, creating a dramatic scene as it advances over the colorful waterpark below. Visible beneath the approaching cloud are bright red, green, and yellow water slides, along with blue, red, and turquoise umbrellas, palm trees, and several buildings. A white building displaying red "FIRST AID" signs and pool rules can be seen, while a large rock-style climbing feature decorated with palm trees stands among the attractions. A small number of visitors are visible on pathways and near the slides, though attention is drawn primarily to the imposing weather overhead. "Awesome shelf cloud coming over Myrtle Waves WaterPark. Video taken by me." The striking cloud formed on June 14, 2026, as part of typical summer thunderstorm activity along the South Carolina coast. Shelf clouds develop along the leading edge of a thunderstorm's outflow boundary, where cooler air surges outward ahead of the storm and can signal the approach of strong winds, heavy rain, or gusty conditions. These formations are common during the warm season in the humid Southeast and serve as dramatic visual warnings of incoming weather. The footage highlights the dynamic skies that frequently accompany coastal thunderstorms in the Myrtle Beach area.
