Rainfall reached over 10 inches (250 mm) in the coastal region of Jalisco, and lighter amounts of precipitation extended further to the southeast and northeast. One person was reported missing in Jalisco. The heaviest 24‑hour rainfall total in the state of Sinaloa was 8.66 inches (220 mm), whereas in Sonora a maximum of 4.72 inches (120 mm) of rain were recorded. Strong waves from the hurricane struck the Mexican mainland, with four people injured at Mazatlán when their boat washed onto rocks and was destroyed. Rainfall from the storm flooded 15 communities in and around Mazatlán, and the Army assisted residents in emergency evacuations. At Los Mochis, near the point where Isis made landfall, the hurricane resulted in the destruction of 300 homes, as well as in seven fatalities. Throughout the city, strong winds from the hurricane downed street posts, tree limbs, and power lines, with one person seriously injured from a downed power line. Additionally, the roof of a gas station collapsed from the winds. More than 1,200 bus passengers in Sinaloa were stranded due to road closures from the hurricane, including the closure of the coastal highway in the southern portion of Sinaloa as it had been washed out due to floodwaters. Rainfall from the storm caused severe river flooding in some locations, and authorities advised those living along the Fuerte River to be prepared for a possible evacuation. The winds from Isis left about 120,000 people in the municipality of Ahome without power.
