the time that the system was facing strong easterly wind shear and was slightly elongated from northeast to southwest, inhibiting potential strengthening. It was also located on the eastern side of a broad monsoon gyre, inducing an eastward-to-northward motion. Despite this, cloud tops south and west of Hernan's center cooled to between as convection increased, allowing the cyclone to strengthen slightly. Hernan peaked at 06:00 UTC on August 27 with maximum sustained winds of and a minimum barometric pressure of . Continuous wind shear caused Hernan to weaken, restricting convection to the southern and western confines of the storm's center. Moving around the northeastern periphery of the large cyclonic gyre, Hernan moved over the Gulf of California and turned west early on August 28. The system was downgraded to a tropical depression at 12:00 UTC that day as most of its convection dissipated. Hernan weakened into a remnant low six hours later. The remnants of Hernan continued westward around the gyre containing Tropical Storm Iselle, which was located to the south. By 00:00 UTC on August 29, the remnants were completely absorbed into this feature. Impact Hernan had a notable impact in multiple western Mexican states despite its small size. A total of 97,000 people lost electricity in the country due to the storm. Over 250 state and federal workers were dispatched to areas affected by Hernan while different agencies traveled by helicopter to bring food and supplies. Mexico's Secretariat of the Navy, José Rafael Ojeda Durán, implemented the Marine Plan, which carried out the evacuation of people trapped by flooding, removed debris, cleaned beaches, and transferred food and equipment to victims. Over 450 units of army machinery were used: 60 maritime units, 6 aircraft, and 391 land units. At least seven people were rescued by air following inundation of their houses by flood waters. Jalisco Jalisco and Colima were placed under the "high risk" category for floods and landslides due to expected rains of up to 8.8 cubic feet (250 liters) per square meter. Rainfall peaked in Jalisco at in Cihuatlán and in Apazulco. Heavy rains from Hernan left 30 communities in Jalisco without power. 400 people were evacuated prior to Hernan's passing, while 18 people stuck on their roofs were rescued as well. Rescues were required for people trapped in houses where rainfall reached up to . Landslides and mudslides covered parts of Mexican federal highways 80 and
