Hurricane Otis unleashed a “nightmare scenario” on Acapulco in southern Mexico Wednesday morning after the storm rapidly intensified into a Category 5 just before landfall and gave officials and residents little time to prepare.

Otis strengthened from a tropical storm to an extremely dangerous Category 5 hurricane in just 12 hours before it slammed ashore near Acapulco as the strongest storm on record to hit this area and the Pacific coast of Mexico.

The sudden burst of power gave people little time to prepare and get to safety as Otis bore down on Acapulco, a popular tourist destination that’s also a permanent home to roughly 800,000 people.

As Otis kept strengthening as it neared the coast forecasters at the National Hurricane Center warned that a “nightmare scenario is unfolding.”

“There are no hurricanes on record even close to this intensity for this part of Mexico,” the hurricane center said late Tuesday.

Studies have shown that rapid intensification of tropical systems is happening more frequently , especially as storms approach landfall, as as oceans warm because of human-caused climate change.

Otis’ center slammed into Mexico’s coast, near Acapulco, at around 12:25 a.m. local time with sustained winds of 165 mph, the National Hurricane Center said.

Within hours, the storm’s maximum sustained winds had slowed to 110 mph, the hurricane center said, with the dangerous hurricane-force winds extending up to 30 miles from Otis’ center.

The hurricane was about 60 miles north-northwest of Acapulco as of 8 a.m., the center said.

The storm is expected to rapidly weaken as it presses inland and over southern Mexico’s higher terrain, where it will likely dissipate Wednesday night, the hurricane center said.

On Tuesday night, Mexican President Andrés Manuel López Obrador implored coastal residents of the state of Guerrero, which includes Acapulco, to seek shelter and stay away from rivers, streams and ravines ahead of the storm’s landfall.

Wednesday morning, Guerrero Gov. Evelyn Salgado Pineda announced temporary shelters were open in Tecpan de Galeana, Coyuca de Benítez and Acapulco.

A hurricane warning is in effect for coastal Punta Maldonado westward to Zihuatanejo.

The winds near Otis’ core are “extremely destructive,” the hurricane center cautioned early Wednesday. Upper floors of high-rise buildings are at greater risk of severe winds than those closer to ground level, the center said.

Otis is also forecast to create storm surge that will likely whip up “large and destructive waves” and life-threatening coastal flooding around the area where it made landfall.

Additionally, between 8 to 16 inches of rain totals are expected through the end of the week, with some areas seeing up to 20 inches of rain. The heavy rainfall could lead to flash and urban flooding as well as mudslides in higher terrain areas, the hurricane center warned.

Otis had been rapidly intensifying throughout Tuesday, gaining 90 mph in a 12-hour period. It became the fastest intensifying hurricane over a 12-hour period in Eastern Pacific history, according to Phil Klotzbach, a research scientist in the atmospheric science department at Colorado State University.

For context, rapid intensification for hurricanes means the storm’s maximum sustained winds increased by at least 35 mph in 24 hours or less. Otis more than tripled this definition when it gained roughly 115 mph in 24 hours from early Tuesday to early Wednesday.

Before Otis, there had not been a Category 5 landfall for the East Pacific, according to the NOAA Hurricane Database. The previous strongest landfall was Hurricane Patricia in 2015, which made landfall as a Category 4 Hurricane with winds of 150 mph.

Unlike Otis, which has made landfall close to a major urban area, Patricia plowed through a sparsely populated and mountainous stretch of the coast, sparing Puerto Vallarta and Manzanillo.

And while Patricia hit the coast as a Category 4 storm, it quickly degenerated and left a narrow path of severe damage it its wake, according to the National Hurricane Center. Two deaths were reported as a direct result of the storm, the center said.
