Apparently such a storm hit the state in 1861-62 and continued over 45 days. Because of massive flooding, the state capital had to be moved from Sacramento to San Francisco for a time (Felicity Barringer, “If Quakes Weren’t Enough, Enter the ‘Superstorm,’” The New York Times, January 15, 2011).
Witnesses described a “river that swept away people and livestock. California’s central valley, now America’s breadbasket [of fruits and vegetables] was turned into an inland sea, impassable for months” (John Harlow, “Biblical ‘Arkstorm’ Threatens LA,” The Sunday Times, March 6, 2011).
Scientists have further warned that if the Los Angeles area were hit by such a storm in the next decade, more than 1.5 million people would be rendered homeless, and the cost could be three times as high as a major earthquake.
A writer for the British magazine Geographicalreports that “all around the world extreme weather events are becoming more frequent and more severe. And while the UK has been hit by several devastating floods in recent years, developing countries continue to be profoundly affected, with Pakistan an obvious recent example” (Mark Rowe, October 2010).
Upsets in the weather and natural disasters both play their part in the prophetic framework given in the Bible. Jesus warned of “great earthquakes” (Luke 21:10 Luke 21:10Then said he to them, Nation shall rise against nation, and kingdom against kingdom:
American King James Version×), which are part of the “beginning of birth pains” (Matthew 24:7-8 Matthew 24:7-8  For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.  All these are the beginning of sorrows.
American King James Version×, New International Version)—signifying that they will, as labor contractions, increase in frequency and intensity as the return of Christ draws nearer. Yet the word for earthquake here, seismos(from which we get seismicand seismology), literally means “shaking” and applies to shakings of the atmosphere (storms) as well as the ground. In fact, the word seismosis elsewhere translated “tempest” (Matthew 8:24 Matthew 8:24And, behold, there arose a great tempest in the sea, so that the ship was covered with the waves: but he was asleep.
American King James Version×) or “storm” (NIV).
So the many hundreds of tornadoes this year, and even Hurricane Katrina of 2005, are by no means the worst weather we can expect. As we approach Christ’s return, we will see more and bigger storms, with accompanying flooding, than we’ve already seen. Yet even a superstorm hitting California may not be the worst of it. Consider that a comet or asteroid impact, which the Bible also seems to warn will come near the very end (see Revelation 8:6-12 Revelation 8:6-12  And the seven angels which had the seven trumpets prepared themselves to sound.
 The first angel sounded, and there followed hail and fire mingled with blood, and they were cast on the earth: and the third part of trees was burnt up, and all green grass was burnt up.
 And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;
 And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.
 And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell on the third part of the rivers, and on the fountains of waters;
 And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.
 And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise.
American King James Version×), could conceivably raise atmospheric temperatures enough to produce massive hypercanes hundreds of miles across with winds over 500 miles per hour. (Sources: The Sunday Times,Geographical[both London], The New York Times.)
