Tropical Storm Hernan was a short-lived tropical cyclone that brought widespread flooding and destructive mudslides to southwestern Mexico in late August 2020. Hernan was the thirteenth tropical cyclone and eighth named storm[a] of the 2020 Pacific hurricane season.[2] The system developed from a low-pressure area to the southwest of Mexico on August 26, as a low-end tropical storm. Moving generally northward and paralleling the west coast of Mexico, Hernan was hindered by a high wind shear environment and only slightly strengthened. The cyclone achieved its peak intensity around 06:00 UTC on August 27 with maximum sustained winds of 70 km/h (45 mph) and a minimum barometric pressure of 1,001 mbar (29.6 inHg). Passing just offshore of the state of Jalisco, Hernan turned west and degenerated to a remnant low on August 28. The low passed near the southern tip of the Baja California Peninsula later that day and dissipated shortly thereafter.
Despite Hernan's short existence, it dropped more than 280 millimeters (11 inches) of rain across many areas of southwestern Mexico, with accumulations peaking at 590 mm (23.24 in) in Jalisco. Multiple highways had to be shut down due to dangerous conditions, including mudslides and rivers overflowing their banks. Several schools suffered damage in the state of Colima, and in the city of Manzanillo, homes, businesses, and streets were damaged and covered in mud. Nearly 20,000 people were greatly affected by Hernan in Jalisco, and 1,674 houses and 9 schools suffered severe damage. In that state, a man fell off his roof and died while inspecting it for damage following the storm. Severe damage was also reported in Guerrero, with the most significant flooding taking place in the Costa Grande region. Lesser effects of the storm were felt in several other coastal states across western Mexico. Recovery efforts were undertaken by the Mexican Armed Forces across several states. Total damage from Hernan in Mexico was estimated to be MXN$594.05 million (USD$26.91 million).[b]
