Parts of Mexico’s Pacific coast, including the port city of Manzanillo, have been placed under a tropical storm watch with the eastern edge of Hurricane Bud potentially scraping the shoreline as it moves north.

Bud, a category 3 hurricane with top winds of 115 miles (185 kilometers) an hour, was about 235 miles southwest of Manzanillo moving northwest at 10 mph, according to a U.S. National Hurricane Center advisory at 8 a.m. New York time. Manzanillo is home to a liquefied natural gas import terminal and is a large container port on Mexico’s Pacific coast.

“On the forecast track, the core of Bud and its stronger winds are expected to remain well offshore of the southwestern coast of mainland Mexico during the next few days,” the advisory said.

Bud’s strongest winds reach out 35 miles from its core, while its winds of at least 39 mph — tropical storm strength — extend 125 miles, which means they could touch the coast as it moves past. It could also drop 3 to 6 inches (8 to 15 centimeters) of rain in Mexico causing flash floods and mudslides.

The storm is forecast to weaken as it moves north, potentially reaching the resort area of Cabo San Lucas by Friday.
