Like the Extreme heat, although there were signs of changing temperature, the sudden spike or the palpable change in temperature was relatively sudden.
For example, back in the Extreme Heat the temperature lowered bit by bit—by very little, almost undetectable—a couple of days before the end. But when it ended completely, it was like the weather just suddenly changed one morning.
Extreme Cold was the same. Starting a few days prior, the temperature increased by about one degree every day, but then it suddenly normalized, increasing by 50 or so celsius in one go.
And what would happen when meters-deep of snow suddenly melted?
Flooding, of course.
People who were walking along the thick blankets of snow would be carried by the strong waters in the span of a few hours.
The real threat was the movement of water, however. Water on its own did not cause the major disasters. It was the speed of their movement—the momentum.
