NOAA Cancels La Niña Watch: Could The Blob Have Helped?



CALIFORNIA - It seems that the NOAA has joined the ranks of those no longer expecting a La Niña winter. It has canceled its watch for the seasonal pattern that was in place the last several months.

Typically peaking between December and February, La Niña is associated with dry winter conditions that would deter any progress the West Coast might have made during the El Niño events of last winter.

As we reported previously, the Climate Prediction Center (CPC), a subsect of the National Weather Service, released a monthly forecast also predicting La Niña is no longer likely to occur, despite last month’s statement that La Niña conditions were favored to occur with a 55-60 percent chance.

Those have slipped down to the 40 percent level, according to The Weather Channel, leaving room for the possibility but removing any expectations.

In an interesting turn, the anomaly brewing off the West Coast, fondly known as The Blob, could be a contributing factor shielding California from La Niña conditions.

Art Miller, Head of the Ocean and Atmosphere Section, Scripps Institution of Oceanography“These are really strong anomalies,” Art Miller, Head of the Ocean and Atmosphere section at UC San Diego’s Scripps Institution of Oceanography, told the San Diego Union Tribune. “They’re far larger and more persistent and spread out over larger areas than we think we’ve ever experienced.”

La Niña conditions brew when temperatures in the ocean cool, opposite of the warming brought on by El Niño. The Blob, as we’ve reported in the past, brings temperatures 2 to 3 degrees Celsius above average, which could be preventing La Niña conditions.

So what’s in store for us this winter? Despite predictions of much needed moisture from the Farmers Almanac, it is still too soon to tell.
