Significant Events
The Eastern Pacific hurricane season finally began June 26 when Hurricane Alvin developed as a tropical storm. This marked the third latest start to the season since since the beginning of satellite monitoring. Both 1969 and 2016 had their first storms on July 2, although 2016 also had a Central Pacific storm in January.
Before Alvin's genesis, tropical storm formation had been suppressed by the dry phase of the Madden–Julian Oscillation (MJO). The wet phase of the MJO remained stalled over the Central Pacific through the end of June because of interactions with the ongoing El Niño. However, the dry conditions weakened over the eastern Pacific. Two eastward moving atmospheric waves, called convectively coupled Kelvin waves, each brought more favorable conditions. One led to Alvin and the other to Hurricane Barbara. Both storms stayed out to sea and did not create any significant impacts.
