Triple threat: Watch as 3 waterspouts swirl off the Alabama coast
MOBILE, Ala. - It’s like a scene from the movie "Twister" – but only over water.Beachgoers in Alabama watched as not one, not two but three waterspouts danced on Mobile Bay Monday morning.More waterspouts were spotted along the coast, prompting the National Weather Service in Mobile to issue a Special Marine Warning for South Mobile Bay, North Mobile Bay and Mississippi Sound.While there was no threat to land, the fair-weather waterspouts are common this time of year through early fall along the Gulf Coast.WHAT IS A WATERSPOUTThese types of waterspouts usually form during relatively calm weather and are not associated with thunderstorms.A screengrab from a video shows three waterspouts near Mobile Bay, Alabama, on June 20, 2022. (Credit: Kelly Woods via Storyful) The NWS says that the fair-weather waterspouts generally happen during the early to mid-morning and sometimes during the late afternoon and form along dark flat bases of a line of developing cumulus clouds. "Strong temperature gradients between the water and land help create these localized areas of spin (vorticity) at the surface owing to sharp but usually weak changes in wind direction over the bay and adjacent gulf waters," NWS Mobile meteorologists told FOX Weather. The change in wind direction causes rotation. "In most cases like we saw today, we had a thunderstorm that developed over the area of vorticity that helped to stretch that up into the air.
