However, as the system turned towards the coast of Mexico, Pamela restrengthened to a low-end hurricane before making landfall over Estacion Dimas, Sinaloa on 15:00 UTC on October 13 before rapidly weakening inland.

[6] that night, convection got further concentrated into its low level circulation center (LLCC), although it became partially exposed due to northeasterly wind shear.

However, gale-force winds were detected by a scatterometer pass in its northeastern quadrant and as a result, the NHC upgraded the depression to a tropical storm, assigning it the name “Pamela” on 21:00 UTC.

[7] Despite the shear and dry air, Pamela continued to intensify near hurricane status on the next day and becoming a fully-fledged Category 1 system, twelve hours later while turning northwards.

[8][9] Pamela underwent a convective bursting phase at this time, and it continued intensifying slowly to its first peak of 70 knots (130 km/h; 81 mph) regardless of wind shear disrupting its outflow layer before weakening to a high-end tropical storm at 21:00 UTC on October 12, based on the data retrieved from an Air Force reconnaissance aircraft that investigated the system that day.

[10][11] By the next day, Pamela turned to the north-northeast and maintained its tropical storm intensity before reintensifying to a low-end Category 1 hurricane once again as the system neared the coast of Mexico on 09:00 UTC on October 13.

[12][13] Three hours later, Pamela made landfall over Estacion Dimas, Sinaloa with winds of 75 mph,[14] soon after it was downgraded to a tropical storm at 15:00 UTC while located inland.

[18][19] The Comisión Nacional del Agua (National Water Commission) also issued an alert for the Mexican state of Sinaloa due to the possible threat of Pamela.

The storm was also anticipated to bring heavy rainfall with possible landslides, strong winds, rough seas and a possible increase in water levels of streams and rivers throughout the coastal and inland areas of Baja California Sur, Sinaloa, Durango and Nayarit, according to the Servicio Meteorológico Nacional.

[22] The government of Sinaloa put 10 of its southern municipalities in red alert due to the threat of the storm while 13 flights were canceled by the Mazatlán International Airport for October 13.

A stream on Colimilla overflowed due to heavy rains, resulting in people in the place crossing by boat to go through the nearby Barra de Navidad, Jalisco.

On October 11 in that morning, a hotel worker in Colima tried to cross a stream, but was unsuccessful as the person were already swept away by the current; however, they managed to escape the accident without being harmed.

The waters of the river that passes through Huajicori was reported to have been rising due to the amount of rainfall being collected along the mountainous areas of Durango and Zacatecas, forcing the passage through Quiviquinta, a town over Nayarit to be temporarily closed.

The Tepic-Mazatlán highway was also included in the affected areas by the overflowing of the said river, in which two people were trapped in the Tecuala toll booth, with one person being swept away and the other being rescued.

[41] Despite dissipating over the mountainous terrain of Mexico, Pamela's remnant moisture moved into Texas, where two individuals were killed after they were swept into a creek in Bexar County.
