  • Sea-surface temperatures in the equatorial Pacific indicate that moderate El Niño conditions currently exist.  According to CPC, El Niño is expected to continue, though gradually weaken, through the spring.  The three-month outlooks for the Southern Plains are consistent with the general impacts expected during El Niño events and global climate model output.  An El Niño Advisory remains in effect.
