Tropical Storm Simon Intensifies Toward Mexico’s West-Central Coast

Key points

• Simon formed in the Pacific Ocean off southwestern Mexico on October 7, 2026, with maximum sustained winds of 50 mph.
• The National Hurricane Center forecasts Simon to become a major hurricane by late Friday or early Saturday, with peak winds reaching 125 mph.
• Heavy rainfall of 8 to 12 inches is expected in parts of southwestern Mexico, with isolated totals of 15 to 25 inches possible in Colima and Michoacán, risking mudslides.
• Manzanillo, Barra de Navidad, and Puerto Vallarta face high probabilities of tropical-storm-force winds, with Manzanillo having a 68% chance.
• The storm is expected to move inland over northwestern Mexico by early next week, weakening as it approaches the coast.

Background

Simon is the 18th named storm of the 2026 Eastern North Pacific season. Earlier this year, Tropical Storms Karina and Lowell formed in the Pacific, and Atlantic storms like Dolly and Fay were monitored, but Simon is the first major threat to Mexico’s west-central coast this season.

How outlets are covering it

AP News reported Simon’s formation and initial status, while Weathernews provided detailed forecasts on intensification, wind probabilities, and rainfall impacts. The U.S. Embassy in Mexico issued a weather alert but its page was inaccessible, limiting its contribution. Weathernews emphasized the rapid intensification and major hurricane potential, while AP focused on the storm’s formation and location.

Why it matters

Simon’s rapid intensification and potential for major hurricane strength pose severe risks to Mexico’s west-central coast, including life-threatening flooding, mudslides, and dangerous surf. Coastal communities and maritime operations must prepare for significant impacts.

What to watch

Simon is expected to make landfall or approach the coast as a major hurricane on Saturday, with weakening forecast as it moves inland over northwestern Mexico by early next week. Residents in high-risk areas should monitor updates from the National Hurricane Center.
