Buffalo, Blizzard of '77. Basically what happened was that Lake Erie froze early due to unusually cold weather. In the subsequent weeks, the frozen lake was covered with a fine, powdery snow. From Thanksgiving up to the blizzard that began at the end of January, the temperature never got above freezing so the snow just built up on the lake and in the city. When the blizzard hit on January 28th, the 40-60 mph winds blew all the snow on the lake right into the city. Drifts of over six feet covered roads in just an hour. Within a day, there were drifts over 25 feet, trapping some cars beneath underpasses in a tomb of snow. The drifts at our house nearly came up to the second floor windows in spots.
For three weeks, the winds stayed strong, the temperatures stayed frigid, and the snow kept coming. The schools were closed. There was a driving ban in the city. Though I lived in Buffalo, I played for a suburban hockey team and the only way we could get to the games was with my friend's father who was a doctor so was exempt from the ban. I'm not sure what he would have said if the police pulled him over with three kids and their hockey equipment in the car.
A few dozen people died.
Now I live in Atlanta and the city is paralyzed with an inch. :-)
