Hurricane Simon Forecast to Reach Category 4 Before Approaching Mexico

Verified Baseline

Simon is rapidly intensifying south of Manzanillo

At 3 a.m. Central Standard Time Friday, the U.S. National Hurricane Center located Simon about 220 miles south of Manzanillo with maximum sustained winds of 90 mph. The storm was moving northwest at 5 mph.

A hurricane warning was in effect from Punta San Telmo to Punta Mita. A tropical-storm watch covered the coast east of Punta San Telmo to Lázaro Cárdenas. The NHC said Simon's core was expected to approach southwestern and west-central Mexico on Saturday, with tropical-storm conditions possible before hurricane conditions arrive.

What is forecast, not yet observed: Simon is expected to continue rapidly intensifying and become a dangerous Category 4 hurricane by Saturday. Forecast intensity, the exact track and the eventual landfall point can still change.

Why It Matters

The heaviest damage may extend far beyond the eye

The NHC forecasts 8 to 15 inches of rain over parts of southwestern Mexico through Sunday, with isolated totals up to 25 inches in Michoacán, Colima, Jalisco and Nayarit. On steep terrain, that amount can trigger life-threatening flash flooding and mudslides well inland from the coast.

A dangerous storm surge is possible near and east of where the center reaches land, accompanied by large, destructive waves. Swells can also create hazardous surf and rip currents before the storm's closest approach.

Analysis: Simon combines three compounding risks: rapid strengthening that shortens preparation time, a slow approach that can prolong rainfall, and mountainous terrain that converts heavy rain into localized flooding and slope failures. Wind category alone does not capture those hazards.

Practical Implications

What residents and travelers should check

• Follow local orders: municipal and state civil-protection instructions determine evacuations and shelter access. A warning means outside preparation can become difficult or dangerous before the center arrives.
• Check official updates: the NHC is issuing frequent advisories, while Mexico's Servicio Meteorológico Nacional and civil-protection agencies provide local information.
• Avoid floodwater and unstable slopes: rain impacts can occur far from the forecast center line and after peak winds pass.
• Travel plans may change: verify flights, highways and lodging directly with operators and authorities, especially in coastal Jalisco, Colima, Michoacán and Nayarit.
• Use the forecast cone correctly: it describes the probable path of the center, not the full area where wind, rain, surge or surf may occur.

What Remains Uncertain

Small track changes could shift the worst conditions

The precise landfall location and timing remain uncertain, and later advisories could expand or move watches and warnings. Rapid-intensification forecasts are also difficult: Simon could strengthen faster or less than projected, and interaction with land can alter the wind field.

Forecast: on the NHC's current track, conditions should deteriorate along parts of the warned coast beginning Saturday, with the core approaching later Saturday and hurricane conditions possible Saturday evening or Sunday.

Opinion: Health Politics Daily does not rate storms by spectacle. The most useful measure is whether official warnings, rainfall and local evacuation information reach people early enough to reduce harm.
