 Early forecasts underestimated the peak intensity of Pauline by 65 mph ( 105 km / h ) . On October 7 , about 41 hours before landfall , the government of Mexico issued a hurricane warning from Tapachula in Chiapas to Punta Maldonado in Guerrero . Shortly after Pauline made landfall , the warning was extended northwestward to Manzanillo , Colima , and later to Puerto Vallarta , Jalisco . Pauline 's turn to the west @-@ northwest near landfall was unexpected , resulting in hurricane conditions with only a few hours notice in some areas .
