Rain, snow and California’s drought
In October, the National Oceanic and Atmospheric Administration announced that the Pacific Ocean was showing signs of a new La Nina, the back of El Nino’s ocean warming pattern, which tends to cause changes in the weather worldwide.
Forecasters said large parts of California would have a 33% to 50% chance of precipitation below normal, while only the northern part of the state had equal chances of above or below normal precipitation.
But the mainstay has been trending farther south than usual under La Ninas. After a series of storms from mid-December, California’s total snow-water equivalent – a measure of how much water is in the snow package – jumped from 19% of normal to December 10 to 76% of normal on December 17, according to the latest U.S. seasonal drought outlook.
Although the current wet trend is positive, it is too early to know if it will last through January and February. The snow pack usually does not reach its maximum until April, and last spring there was minimal runoff because much of the water was absorbed by the drought-dried landscape.
