Cat 5 Hurricane Otis making lanfall near Acapulco, Mexico
Major Hurricane Otis continued to strengthen until near the time of landfall in southern Mexico near Acapulco, reaching a catastrophic Category 5 with max wind of 145 kts (165 mph).
Otis intensified very rapidly from a tropical storm to a Cat 5 hurricane in about 18 hours as it moved over sea surface temperatures from 28 C to about 30 C as it approached the coast. Although the SSTs are warm, they are not all that unusual for the area. The very rapid intensification will be a subject for further study. In 2015 Hurricane Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours with max winds of 185 knots (215 mph) but weakened to 130 kts (150 mph) at landfall. 
Otis has moved onshore in the greater Acapulco area and now that the center is moving inland, rapid weakening is expected.
