Summary

A tropical disturbance in Mexico's Pacific reached a 90 percent probability of becoming Tropical Storm Fausto by July 18, located south-southwest of Acapulco and tracked by Mexico's national meteorological service. Authorities placed Baja California Sur on alert. A second system, Elida, was simultaneously developing offshore, raising the risk of two storms affecting Mexico's Pacific coast during the same period. Mexico's 2026 Pacific hurricane season has already produced multiple storms earlier than average.

Why it matters

Baja California Sur's principal settlement La Paz and its tourist infrastructure along the corridor to Los Cabos face disruption if Fausto strengthens and curves toward the peninsula, as eastern Pacific storms periodically do. A simultaneous Elida development complicates emergency resource allocation. Mexico's agricultural and fishing sectors along the Sinaloa and Guerrero coasts face a separate exposure if the storm makes landfall on the mainland side.

What to watch

  • Whether the disturbance achieves tropical storm status and what track it takes once named
  • Whether Elida and Fausto interact, potentially affecting each other's intensification or track
  • Whether Guerrero state authorities issue evacuation orders for coastal zones south of Acapulco
