Something fishy happened during the hailstorm that pounded the city Tuesday evening. Gulf Islands National Seashore Ranger Melissa Perez and volunteer Adam Wilson were pelted briefly with small, very cold fish while on the park's pier.It was around 6 p.m. Tuesday when the storm had eased briefly. The two ran out to try and locate minnow traps that had been left on the pier.The traps were gone, but while Perez and Wilson were looking, something began falling into the water near them causing splashes. Then two icy cold fish hit the deck of the pier and one hit Perez's hat."I was pretty upset that I had lost those traps, when fish fell from the sky," Perez said."We went for cover. One was incredibly cold and one of them actually was icy," she said. Fellow workers told her it was a rare phenomenon."But sure enough, it happened here," she said.Perez didn't know how many fell into the water; the event took her by surprise. But it all happened in an area that had roughly a 20-foot diameter.The fish that hit the deck were small, about 3 inches long, and she said that she didn't immediately recognize the species."The weather was so bad that we threw them off and ran for cover," she said.Todd Adams, assistant coordinator of educational programs at J.S. Scott Marine Education Center, has a degree in physical geography and a master's in geo-science.He ventured two possibilities: The storm could have pulled the small fish into the thundercloud where they were coated with ice until they got heavy enough to fall from the cloud or the storm could have sucked them off a fishing boat and dropped them at the park."Obviously there was hail," Adams said. "And a water spout will pull up and throw all types of things."
