North east Pacific cool coastal waters, indicative of a negative PDO still in situ.
A small area has warmed over the last week, could be signs of a change in PDO but further obs required. east Pacific now over 2c warmer than avg, (1+2). Latest 3.4 SSTs 0.4c, static since 26.4. pic.twitter.com/lqMov4rTNZ
