HISTORY WASHED AWAY 🌊: Torrential rain and flash flooding swept through New York's Hudson Valley on Wednesday, washing away a nearly 300-year-old gristmill. The relic of history was no match for the raging floodwaters that engulfed a roadway in Castleton-on-Hudson as the region grapples with some of its highest rainfall totals in a decade. #FOXWeather #newyork #flood #history #rain #HudsonValley #gristmill #weather #northeast
