      Here is the SOI index for the last two days:

      11-May-2002 1006.46 1009.60 -35.70 -4.20 -2.55
      12-May-2002 1009.41 1011.00 -23.80 -4.92 -3.11

      Of interest is the two tropical storms to the west of the tropical
      Pacific and the Darwin BP dropping then now rising but with this
      flaring the Tahita BP rising, otherwise we may have gone back to
      zero. I suspect that if the tropical storms take some energy out of
      the SSTs to the west of the Pacific we may see some trending back to
      an El Nino SOI but we are now in the East Pac hurricane season and so
      the Eastern Pacific is going to have a chance to cool with these
      storms. We shall see.
