American Somoans!

HotSpots have been lurking to the west of you [yes, more toward Samoa]
but close to what we believe to be critical since early March!  We have
learned a few weeks ago that some corals were observed to have bleaching
in or around Fagatele Bay...You can you see our newest posting (April
SSTs about to update):

Presently we are showing SSTs at 29.6... flirting with 30C!

Keep those corals shaded!
