Florida authorities had to rescue a 14-year-old by boat after the boy became stranded on floating debris. In a video posted on Facebook Thursday, the Hillsborough County Sheriff's Office said the boy became submerged in floodwaters after Hurricane Milton struck the night before. The video shows the officers arriving by boat and lifting the teen from the water. Milton made landfall in Siesta Key Wednesday night after weakening from a Category 5 to a Category 3 due to wind shear. It caused extensive damage, though Florida Gov. Ron DeSantis said the area was spared from the worst-case scenario that officials feared. Still, more than 3 million Floridian customers were without power hours after the hurricane exited to the Atlantic.RELATED STORY | Over 2 million without power as Hurricane Milton wallops Florida with destructive winds, floodingEarly Thursday, first responders and other crews worked to clean up the downed trees that fell on cars and homes and rescue any residents who'd become trapped due to flooding.
