Cold is slow to worsen. Then it's fast.
A large ice jam formed and released on the Ausable River at Au Sable Forks, NY on January 12, 2018. The ice jam was caused by a combination of rapid snow melt with moderate rain in abnormally warm temperatures. The gauge peaked at 13.27 ft and the gauge data showed that the river rose exactly 7.75 ft in 14 minutes during the peak rise meaning the river rose at just over half a foot a minute at that time.
