Weather disruption affected access to Mexico's Pacific ports on 11 October, according to ADN Noticias' account of restrictions imposed by the Secretariat of the Navy.[11] The publication listed Manzanillo in Colima, Lázaro Cárdenas in Michoacán and Puerto Vallarta in Jalisco among ports closed to larger vessels.[11]
The report distinguished restrictions on larger ships from those applying to small vessels.[11] Its small vessel list included Puerto Marqués in Guerrero, Barra Navidad in Jalisco and Teacapán in Sinaloa, while Lázaro Cárdenas appeared in both categories.[11] The publication warned that the restrictions could change as weather conditions developed.[11]
At 0600 UTC on 12 October, the National Hurricane Center's Advisory 19A put Simon's maximum sustained winds at 115 mph, down from the earlier advisory but still Category 3.[15] Hurricane warnings remained in force from Playa Perula to El Roblito and for Las Islas Marias.[15] The center forecast further weakening, but expected Simon to remain a hurricane through midweek.[15]
The closure list describes reported restrictions on 11 October, not a verified live port status for 12 October. No current port captain order or authoritative reopening notice was retrieved for this summary. The NHC bulletin supplies the later weather assessment, not confirmation that cargo operations have resumed.
