Tropical Storm Alvin Weakens, Brings Rain to Southwest U.S.

Los Cabos, Mexico – Tropical Storm Alvin is expected to dissipate into a remnant area of low pressure this weekend, but its moisture will impact the Southwest United States.

Currently, Alvin is located over 400 miles south of Los Cabos, well off the western coast of Mexico. The storm is moving into unfavorable conditions such as wind shear, cooler waters, and drier air, which will lead to its deterioration by early this weekend.

Parts of Mexico’s Pacific coast will face high surf and rip currents as the only lingering impacts from this system. While Alvin nears Mexico’s southern Baja Peninsula, its moisture will affect the weather across the Southwest U.S., particularly by Sunday.

Areas like Phoenix and Tucson will see enhanced rain, creating an unusual weather pattern for the end of May and start of June, when typically rain is scarce. Generally, June is one of the driest months in this region before the summer monsoon arrives.

This year has already seen an early start to the hurricane season, with activity commencing two weeks before the Atlantic hurricane season. Most Eastern Pacific storms fizzle out in open waters, but some make landfall, as seen earlier this year.

Forecasters are keeping a close eye on Alvin’s remnants as they may contribute significantly to upcoming weather conditions in the Southwest.
