Pat Shingleton: "The Big One..."
The needed rain in California won't put a dent in their drought. It is wet-weather season there and no season compares to what the state experienced 153 years ago. From December, 1861 to January, 1862, a 30 day event translated to a 30,000 year flood event. Rain was reported in the state on 28 out of 39 days. San Francisco logged 34 inches of rain, Sacramento picked up 37 and Nevada City, in the Sierra Nevada Mountains, recorded snow depths that were equivalent to 115 inches of rain. During that time period, Los Angeles reported 35 inches of rain. Weatherwise Magazine reports that the reason for the deluge was a bulge in the jet stream and a stalled trough of low pressure. More rain is needed to break the existing drought in California.
