The darkness drops again; but now I know   

That twenty centuries of stony sleep

Were vexed to nightmare by a rocking cradle,   

And what rough beast, its hour come round at last,   

Slouches towards Bethlehem to be born?

I don’t think Yeats’ enigmatic lines from The Second Coming, no more than the poem itself have ever been fully fathomed. But that has not stopped them being lauded to in countless literary and other contexts. Today and now they echo through the catastrophic events taking place in Los Angeles as the city burns from the flames fanned by the rough beast, the Santa Ana which descended on it from the valleys to its east.

The incomparable late Joan Didion chose as the title for her most famous collection of essays and journalism, Slouching Towards Bethlehem. In that collection, in a section entitled ‘Los Angeles Notebook, she has a short four-page piece on the natural phenomenon which has now devastated the richest city in America, and probably in the world at an estimated cost of $50 billion.

Didion wrote her piece in the late nineteen sixties. We are shocked by what we are witnessing today in that great city which has played such a significant part in the moulding of our modern culture. If we had remembered what She wrote back then about the phenomenon of this mighty wind we might not have been saddened but perhaps not so shocked.

I take the liberty of giving you the essay here in full – with the recommendation to read Slouching Towards Bethlehem from cover to cover.

There is something uneasy in the Los Angeles air this afternoon, some unnatural stillness, some tension.

What it means is that tonight a Santa Ana will begin to blow, a hot wind from the northeast whining down through the Cajon and San Gorgonio Passes, blowing up sandstorms out along Route 66, drying the hills and the nerves to the flash point. For a few days now we will see smoke back in the canyons, and hear sirens in the night. I have neither heard nor read that a Santa Ana is due, but I know it, and almost everyone I have seen today knows it too. We know it because we feel it. The baby frets. The maid sulks. I rekindle a waning argument with the telephone company, then cut my losses and lie down, given over to whatever it is in the air. To live with the Santa Ana is to accept, consciously or unconsciously, a deeply mechanistic view of human behavior.

I recall being told, when I first moved to Los Angeles and was living on an isolated beach, that the Indians would throw themselves into the sea when the bad wind blew. I could see why. The Pacific turned ominously glossy during a Santa Ana period, and one woke in the night troubled not only by the peacocks screaming in the olive trees but by the eerie absence of surf. The heat was surreal. The sky had a yellow cast, the kind of light sometimes called “earthquake weather.” My only neighbor would not come out of her house for days, and there were no lights at night, and her husband roamed the place with a machete. One day he would tell me that he had heard a trespasser, the next a rattlesnake.

“On nights like that,” Raymond Chandler once wrote about the Santa Ana, “every booze party ends in a fight. Meek little wives feel the edge of the carving knife and study their husbands’ necks. Anything can happen.” That was the kind of wind it was. I did not know then that there was any basis for the effect it had on all of us, but it turns out to be another of those cases in which science bears out folk wisdom.

The Santa Ana, which is named for one of the canyons it rushes through, is a foehn wind, like the foehn of Austria and Switzerland and the hamsin of Israel. There are a number of persistent malevolent winds, perhaps the best known of which are the mistral of France and the Mediterranean sirocco, but a foehn wind has distinct characteristics: it occurs on the leeward slope of a mountain range and, although the air begins as a cold mass, it is warmed as it comes down the mountain and appears finally as a hot dry wind. Whenever and wherever a foehn blows, doctors hear about headaches and nausea and allergies, about “nervousness,” about “de-pression.” In Los Angeles some teachers do not attempt to conduct formal classes during a Santa Ana, because the children become unmanageable. In Switzerland the suicide rate goes up during the foehn, and in the courts of some Swiss cantons the wind is considered a mitigating circumstance for crime. Surgeons are said to watch the wind, because blood does not clot normally during a foehn. A few years ago an Israeli physicist discovered that not only during such winds, but for the ten or twelve hours which precede them, the air carries an unusually high ratio of positive to negative ions.

No one seems to know exactly why that should be; some talk about friction and others suggest solar disturbances. In any case the positive ions are there, and what an excess of positive ions does, in the simplest terms, is make people unhappy. One cannot get much more mechanistic than that.

Easterners commonly complain that there is no “weather” at all in Southern California, that the days and the seasons slip by relentlessly, numbingly bland. That is quite misleading.

In fact the climate is characterized by infrequent but violent extremes: two periods of torrential subtropical rains which continue for weeks and wash out the hills and send subdivisions sliding toward the sea; about twenty scattered days a year of the Santa Ana, which, with its incendiary dry-ness, invariably means fire. At the first prediction of a Santa Ana, the Forest Service flies men and equipment from northern California into the southern forests, and the Los Angeles Fire Department cancels its ordinary non-firefighting routines.

The Santa Ana caused Malibu to burn the way it did in 1956, and Bel Air in 1961, and Santa Barbara in 1964. In the winter of 1966-67 eleven men were killed fighting a Santa Ana fire that spread through the San Gabriel Mountains.

Just to watch the front-page news out of Los Angeles during a Santa Ana is to get very close to what it is about the place. The longest single Santa Ana period in recent years was in 1957, and it lasted not the usual three or four days but fourteen days, from November 21 until December 4. On the first day 25,000 acres of the San Gabriel Mountains were burning, with gusts reaching 100 miles an hour. In town, the wind reached Force 12, or hurricane force, on the Beaufort Scale; oil derricks were toppled and people ordered off the downtown streets to avoid injury from flying objects. On November 22 the fire in the San Gabriels was out of control.

On November 24 six people were killed in automobile acci-dents, and by the end of the week the Los Angeles Times was keeping a box score of traffic deaths. On November 26 a prominent Pasadena attorney, depressed about money, shot and killed his wife, their two sons, and himself. On November 27 a South Gate divorcée, twenty-two, was murdered and thrown from a moving car. On November 30 the San Gabriel fire was still out of control, and the wind in town was blowing eighty miles an hour. On the first day of December four people died violently, and on the third the wind began to break.

It is hard for people who have not lived in Los Angeles to realize how radically the Santa Ana figures in the local imagination. The city burning is Los Angeles’s deepest image of itself: Nathanael West perceived that, in The Day of the Locust; and at the time of the 1965 Watts riots what struck the imagination most indelibly were the fires. For days one could drive the Harbor Freeway and see the city on fire, just as we had always known it would be in the end. Los Angeles weather is the weather of catastrophe, of apocalypse, and, just as the reliably long and bitter winters of New England determine the way life is lived there, so the violence and the unpredictability of the Santa Ana affect the entire quality of life in Los Angeles, accentuate its impermanence, its unre-liability. The wind shows us how close to the edge we are.
