The warnings in force
A Hurricane Warning covered Punta San Telmo to El Roblito and Las Islas Marias. The centre issues a warning when hurricane conditions are expected somewhere in the area, typically 36 hours before the first tropical-storm-force winds. A Tropical Storm Watch covered the coast east of Punta San Telmo to Lazaro Cardenas, with tropical storm conditions possible from the afternoon of 10 October.
Rainfall, surge and surf
Simon was forecast to produce 10 to 20 inches of rain over portions of southwestern Mexico, with isolated totals of 30 inches possible across parts of Michoacan, Colima and Jalisco through Sunday. The centre described that rainfall as producing life-threatening flooding and mudslides in areas of steep terrain.
A dangerous storm surge was expected along the immediate coast near and east of the forecast landfall point, with large and destructive waves. Swells were expected to produce life-threatening surf and rip currents along both coasts over the following days.
No National Hurricane Center product forecast Simon reaching Category 5. Advisories 13, 13A and 14 each held maximum sustained winds at 150 mph. Discussion 14 expected weakening to begin within 12 to 24 hours, with more substantial weakening once the core moved fully onshore, and showed Simon dissipating over Mexico after 60 hours.
