Wachenfeld acknowledged Wednesday that "the early indications are suggesting that the mortality received’t be very excessive."

Wachenfeld mentioned, "We hope that many of the coral bleached will get well and that we are going to find yourself having an occasion reasonably like 2020, when there was mass bleaching however low mortality."
