A tire series plot of the CIMSS Advanced Dvorak Technique (above) showed that Hurricane Cristina experienced a period of very rapid intensification during the day on 12 June 2014. Hurricane Cristina reached Category 4 status, making this the first time in the satellite era that there have been two Category 4 storms by the month of June in the East Pacific basin (the first this year was Hurricane Amanda).

About 3 hours later, an overpass of a Metop satellite provided ASCAT surface scatterometer winds (below).
