What this article from Wikipedia fails to tell you is scientists have discovered that these storms take place every 150 to 300 years regularly like clockwork for thousands of years into the past. This, for me, is the reason why there were no big cities on the West Coast of the U.S. when Spain first colonized California. We haven't seen this kind of thing before here except for the 1862 arcstorm because it wasn't discovered by Spain when the previous one happened. Since the Native Americans did not have a written language such information would only come down in stories told which was how Native Americans transmitted their histories. However, White Men not speaking any of these languages at the time plus not believing these stories likely was what happened.

The Arkstorm

ARkStorm

From Wikipedia, the free encyclopedia

An ARkStorm (for Atmospheric River 1000 Storm) is a hypothetical but scientifically realistic "megastorm" scenario developed and published by the United States Geological Survey, Multi Hazards Demonstration Project (MHDP). It describes an extreme storm that might impact much of California causing up to $725 billion in losses (most caused by flooding), and affect a quarter of California's homes. The event would be similar to exceptionally intense California storms which occurred between December 1861 and January 1862.^[1] The name "ARkStorm" means "Atmospheric River (AR) 1000 (k)."

Description

A map of the flood areas of the hypothetical ARkStorm, based on the areas flooded during the 1861–1862 ARkStorm event.

The hypothetical ARkStorm, if it occurred, would have the following effects:

The Central Valley experiences hypothetical flooding 300 miles long and 20 or more miles wide.
Serious flooding also occurs in Orange County, Los Angeles County, San Diego, the San Francisco Bay area, and other coastal communities.
Windspeeds in some places reach 125 miles per hour, hurricane-force winds.
Across wider areas of the state, winds reach 60 miles per hour.
Hundreds of landslides damage roads, highways, and homes.
Property damage exceeds $300 billion, most from flooding.
Demand surge (an increase in labor rates and other repair costs after major natural disasters) could increase property losses by 20 percent.
Agricultural losses and other costs to repair lifelines, dewater (drain) flooded islands, and repair damage from landslides, brings the total direct property loss to nearly $400 billion, of which $20 to $30 billion would be recoverable through public and commercial insurance.
Power, water, sewer, and other lifelines experience damage that takes weeks or months to restore.
Flooding evacuation could involve 1.5 million residents in the inland region and delta counties.
Business interruption costs reach $325 billion in addition to the $400 billion required for property repair costs, meaning that an ARkStorm could cost a total of $725 billion, nearly 3 times the amount of damage predicted by the California ShakeOut authors for a severe Southern California earthquake, an event with roughly the same annual occurrence probability.^[1]
