Hurricane Simon strengthens to Category 4 off Mexico coast

Simon is expected to approach the west-central coast of Mexico as a major hurricane late on Saturday or early Sunday, and some additional strengthening remains possible before landfall, the NHC said.

A hurricane warning was in effect for portions of Mexico's Pacific coast south of the beach resort of Puerto Vallarta, including the area around Manzanillo, Mexico's largest Pacific port. ⁠A tropical storm watch was in effect farther south toward Lazaro Cardenas.

The NHC urged residents in the warning area, which also includes the Islas Marias archipelago offshore, to rush preparations to protect life and property. “Simon has strengthened incredibly quickly, and that’s what makes storms like this so dangerous,” said Accu.

Weather meteorologist Dan Pydynowski. “Strong winds could damage homes and businesses, while flooding and mudslides could wash out roads and make it difficult for emergency crews to reach some communities.

Even after the storm passes, power outages and damaged infrastructure could make recovery challenging.”PREPARATIONS UNDER WAY IN MANZANILLOIn the early afternoon on Saturday in Manzanillo, residents appeared largely calm despite the approaching storm, with little sign of panic buying at supermarkets, the ground. Some stores had begun boarding up their windows, while businesses were closing and streets were relatively empty.

Rain had been falling intermittently since late on Friday, and rising seas were pushing waves almost to the ⁠entrances of beachfront hotels, although strong winds had yet to arrive. Civil protection workers had closed beaches, erected barriers and raised red and black warning flags, urging residents to stay away from the shore.

Marines, soldiers, National Guard officers and emergency personnel were patrolling areas vulnerable to flooding and landslides, while authorities had begun precautionary evacuations in parts of Cihuatlan, a flood-prone municipality in neighboring Jalisco state, near Manzanillo. Rivers in some areas were already running high, raising concerns they could overflow if heavy rains intensified.

Mexican authorities warned that heavy ⁠rainfall was expected in the states of Guerrero, Michoacan, Colima and Jalisco.

UP TO 30 INCHES OF RAIN EXPECTEDThe NHC said Simon was expected to produce 10 to 20 inches (25 to 51 cm) of rain across portions of southwestern Mexico through Sunday, with isolated totals of up to 30 inches (76 cm) possible in parts of Michoacan, Colima and Jalisco.

The rainfall ⁠could trigger life-threatening flooding and mudslides, especially in mountainous areas. A storm surge is expected along the coast near and to the east of where the center makes landfall, accompanied by large and destructive waves, the NHC said.

Swells generated by Simon are expected to affect portions of Mexico's southwestern and west-central coast over ⁠the coming days, creating dangerous surf and rip current conditions. Simon is forecast to be near or just inland of Mexico's west-central Pacific coast on Sunday.

Last week, Hurricane Polo made landfall on the Baja California Peninsula as a Category 2 storm, toppling trees and utility poles, flooding streets and causing other property damage.
