El Nino prime culprit for severe weather in California
Three days of severe weather, including mudslides and flooding, is largely courtesy of El Nino, say meteorologists.
This bout of bad weather, say meteorologists, is largely courtesy of El NiÃ±o, which is expected to influence the jet stream throughout the winter months.
In southern California on Wednesday, the third storm in three days brought high winds and continuous rainfall, prompting authorities to issue flash-flood and high-wind warnings. In the north, some 30,000 people lost power, and the stateâs highway patrol reported numerous mudslides along roadways.
On Thursday and Friday, Arizona is expecting as much as four feet of snow in the northern part of the state and heavy rainfall in the center. And Nevadans should prepare for flooding later this week, officials in Las Vegas said. That city was pummeled with heavy rains Tuesday.
While itâs difficult to pinpoint whatâs responsible for a batch of severe storms, many are pointing their finger at El NiÃ±o.
âEl NiÃ±o appears to be showing signs here in this pattern with particularly strong disturbances within the jet stream,â says Greg Carbin, a meteorologist at the National Weather Serviceâs Storm Prediction Center in Norman, Okla. âThe intensity of the mid-level and upper-level winds has been quite dramatic.â
The high winds, which reached 60 miles per hour and toppled power lines in Sacramento and Silicon Valley in California on Wednesday, are expected to taper off as storm systems move east and into Arizona.
As The Seattle Times notes, El NiÃ±o years can bring both stormy weather as well as warmer temperatures.
"My gut feeling is it has something to do with the [ocean-warming] El Nino conditions off California, which is driving prey and sea lions up north," Kim Raum-Suryan, a biologist at the Hatfield Marine Science Center in Newport, Ore., told USA Today.
But while most meteorologists say that El NiÃ±o is at the root of this weekâs rotten weather, some disagree.
âWhile the rest of the country has been battered by strong, cold outbreaks; bringing storms, snow and frigid temperatures over the past two weeks, California remained mild and dry. Now itâs our turn,â wrote Mr. Patzert in an e-mail to the science dude.
But donât blame it on El NiÃ±o, he says.
âThe El Nino warmed subtropics might be pumping a little moisture into these storms as they move south and could be giving rain and snowfall totals a boost. But not much!â he wrote.
