Hurricane Otis was on its way to the popular resort of Acapulco on Tuesday and was poised to make landfall on Mexico’s Pacific coast as an “extremely dangerous” Category 5 storm, Reuters reported.

Otis was expected to make landfall Wednesday morning, bringing strong winds and heavy rain.

According to the US National Hurricane Center, on Tuesday afternoon it was already a category 4 hurricane, with wind speeds reaching 233 km/h.

By 6 p.m. local time (00:00 GMT Wednesday), Otis was about 85 miles southeast of Acapulco and continued to strengthen before making landfall, the NHC in Miami added.

Once Otis reaches shore, he should lose weight quickly, he said.

Hurricane conditions are expected for 12 to 24 hours along the coast between the beach towns of Zihuatanejo and Punta Maldonado in Guerrero state, where Acapulco is located, the NHC said.

The storm could bring up to 38cm of rain to parts of Guerrero and neighboring Oaxaca state, potentially causing flash flooding and mudslides, “life-threatening” storm surges and rip currents and rip currents, the center added.

Guerrero schools canceled classes for Wednesday ahead of Otis’ arrival, Gov. Evelyn Salgado said on social media.

Hurricane Norma killed at least three people as it swept along the northwest coast of Mexico this past weekend. A few days ago, powerful hurricane Lidia hit the Mexican Pacific coast, leaving one dead and several injured.
