AKIPRESS.COM - Residents of a stretch of Mexico's Pacific Coast dotted with resorts and fishing villages boarded up homes and bought supplies ahead of Friday's arrival of Hurricane Patricia, a monster Category 5 storm that forecasters warned could be catastrophic.

Officials declared a state of emergency in dozens of municipalities in Colima, Nayarit and Jalisco states that contain the bustling port of Manzanillo and the posh resort of Puerto Vallarta. The governor of Colima ordered schools closed on Friday, when the storm was forecast to make landfall as a still-deadly Category 4 storm, reports AP.

Rain pounded Manzanillo late Thursday while people took last-minute measures ahead of Patricia, which quickly grew from a tropical storm into a Category 5 hurricane, leaving authorities scrambling to make people safe.

At a Wal-Mart in Manzanillo, shoppers filled carts with non-perishables as a steady rain fell outside.

Veronica Cabrera, shopping with her young son, said Manzanillo tends to flood with many small streams overflowing their banks. She said she had taped her windows at home to prevent them from shattering.

Alejandra Rodriguez, shopping with her brother and mother, was buying 10 liters of milk, a large jug of water and items like tuna and canned ham that do not require refrigeration or cooking. The family already blocked the bottoms of the doors at their home to keep water from entering.

Manzanillo's "main street really floods and cuts access to a lot of other streets. It ends up like an island," Rodriguez said.

In Puerto Vallarta, restaurants and stores taped or boarded-up windows, and residents raced to stores for last-minute purchases ahead of the storm.

The U.S. National Hurricane Center in Miami warned that preparations should be rushed to completion, saying the storm could cause coastal flooding, destructive waves and flash floods.

"This is an extremely dangerous, potentially catastrophic hurricane," center meteorologist Dennis Feltgen said.
