Nina conditions that were a big driver behind colder and wetter weather in the
Columbia Basin “are no longer present” — at least over the Pacific Ocean,
according to a monthly report issued Thursday by the NOAA Climate Prediction
waters have been warming and climate neutral conditions are emerging, and there
are greater-than-even chances of an El Nino climate pattern taking hold during
the second half of this year, the report states.
Nina was expected to produce cooler and wetter weather in the four-state
Columbia Basin, and that prediction panned out with record low temperatures,
and record high precipitation recorded in parts of Washington, Oregon, Idaho
and Montana since last October. Neutral conditions typically produce an
environment of uncertainty for weather forecasters.
report notes that several forecasting models anticipate neutral conditions will
persist through the spring months.
there are increasing odds for El Nino toward the second half of 2017,” the
on its strength, an El Nino weather pattern can produce warmer and drier
conditions in the Northwest. While the El Nino-La Nina Southern Oscillation is
known to be a powerful influence in the Northwest and other regions, such as
the Southwest, they are not the only influences on weather and they do not
produce uniform weather throughout a region. One county may have a record wet
month, for instance, but that may not occur in other nearby counties.
next Southern Oscillation report from the Climate Prediction Center is
scheduled for March 9.
