The National Hurricane Center said on Monday that Hurricane Willa, a potentially catastrophic storm, travelled towards Mexico’s Pacific coast with winds of 155 mph. Forecasters expect the Category 4 storm to make landfall along Mexico’s southwestern coast this afternoon or evening. Willa — described as an “extremely dangerous storm” — is expected to bring life-threatening storm surge, wind and rainfall over west-central and southwestern Mexico. Willa was located about 135 miles south-southwest of Las Islas Marias, Mexico, and some 110 miles southwest of Cabo Corrientes, Mexico, the hurricane center said as of 5 p.m. on Monday. Hurricane warnings were posted for a stretch of shore between San Blas and Mazatlan. A tropical storm warning was in effect for Playa Perula to San Blas and north of Mazatlan to Bahia Tempehuaya.
