Tropical Storm Ivo was a tropical cyclone that brought heavy rainfall to five states in Mexico, causing severe flooding in August 2019. The tenth tropical cyclone and ninth named storm of the 2019 Pacific hurricane season, Ivo arose from a low-pressure area that spawned south of Guatemala on August 16. The low-pressure system gradually organized over the next several days as it tracked west-northwestward. The system coalesced into a tropical depression early on August 21 and strengthened into Tropical Storm Ivo several hours later. Located within a favorable environment of moist air and warm sea surface temperatures, the cyclone quickly intensified, peaking the next day with 1-minute maximum sustained winds of 70 mph (110 km/h) and a pressure of 990 mbar (29.23 inHg). Increasing wind shear caused the storm's intensification to level off later that day, as the system turned towards the north-northwest. Ivo passed by Clarion Island midday on August 23, generating winds of 60 mph (100 km/h) on the island. Wind shear caused Ivo to significantly degrade in structure and intensity during the next couple of days. Cold sea surface temperatures, as well as dry and stable air, caused the cyclone to degenerate into a remnant low early on August 25. The low meandered over the eastern Pacific before opening up into a trough of low pressure early on August 27. Tropical Storm: peak winds of 70 mph (60 knots), lowest pressure 990 mb. August 21 – August 27, 2019. Accumulated cyclone energy: 3.5. Wiki link Track: NOAA National Hurricane Center, HURDAT2 best track EP102019 (public domain).
