A week of heavy snow and rain in Northern California and Nevada caused the worst flooding in the last 10 years. 3 men killed in San Francisco.

Emergency crews decided to take advantage of a one-day break between the snow to rescue people and assess damage after the heavy snowfall over the last 10 years, which hit California and Nevada. The flood left thousands of people homeless and forced them to evacuate to a safe area. The next strong storm hits Northern California today.

The snowfall and rains that fell on California and Nevada last week are part of the "atmospheric river." This system, known as the "Pineapple Express," poses catastrophic risks to areas affected by rain.
