No, I only considered the December - February 3-month season to be consistent with NOAA's Winter Outlook, so any precipitation falling after February 29th is not factored into the analysis. But you raise a good point - the influence of El Nino on western U.S. precipitation extends beyond February, and I believe the relationship is even stronger in March than in December. So, we should expect that the influence of El Nino is not quite done yet.
