Description

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 of the 2020 Pacific hurricane season. 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.
