Apparently, California gets a hurricane or tropical storm about once every eighty years. Previous major storms occurred in 1858 and 1939. Why don’t tropical storms or hurricanes ever hit California? I did not know that the dawn of the 20th century in California occurred in 1939. You learn something new every day.
Not exactly. Hurricanes hitting the U.S. east coast are from prevailing wind currents that are unrelated to the earth's rotation. I was surprised to learn that the reason for hurricanes being pushed from the coast of Africa to the eastern seaboard of the U.S. is a weird effect from the Sahara desert (this was on a Weather Channel-type TV show). The Sahara was not always a desert, but a lush landscape 6,000 years ago. Some global temperature change moved the rain south to central Africa. The border of the Sahara and the wet region to the south somehow creates a westerly wind that flows to the west (called the tradewinds), carrying hurricanes that form off Africa to the U.S. The rotation of the hurricane is due to the Coriolis effect, which is due to the earth's rotation.

California's Bay area is about to get some major rain (and some serious flooding): an "atmospheric river" is headed their way. Coastal areas will get 1-3 inches, and higher elevations will get 3-5". It could be a major disaster with all of the landslides that could happen. Potential Category 4 atmospheric river to hit Northern California (yahoo.com)
the problem is that southern California doesn't retain much. an enterprising farmer would have dikes around their fields and divert as much runoff as possible to flood their fields, especially the almond growers, so that the local water tables could be helped. Capturing excess runoff has not been a part of their water use emergency protocols from anything that I have seen.
True, goes for most of the west. They are more concerned with diverting and run off whereas here in Fl (and the SE), we are more concerned with retention. Maybe because we generally get more rain consistently.
It could have been the tail end of the end of the Ice Age. The Bosphorus (around Istanbul, Turkey) is believed to have flooded around 5600 B.C., filling the Black Sea with water. That was a result of rising water from melting glaciers. It is possible that there were other things happening globally after that time period. Saudi Arabia was also a very green country (a jungle, essentially) 5,000 years ago, but has since turned into a desert. Apparently, another cause of the problem was that earth's "wobble" changes from 22 to 25 degrees based on interactions with other large bodies in our solar system. This changes about every 41,000 years. In 5500-6000 B.C., the earth changed from a 24.1 degree wobble to a 23.5 degree wobble, which is how much the top of the earth leans toward the sun in summer (June 21), I believe. This small change has a great effect on where monsoon rains fall. It took over 1,000 years for Arabia to transition into a desert. Next change is in 33,000 years.

Just being a little snarky here, not directed at you though. I just thought from all accounts that climate change was due to the great amount of CO2 output by man since the industrial revolution. I can hardly wrap my head around the fact that climate change happens without man being the cause!! lol
