Part of the 2021 Pacific hurricane season

Tropical Storm Dolores was a strong tropical storm that made landfall in southwestern Mexico in June 2021. The fourth named storm of the 2021 Pacific hurricane season, Dolores developed from a low-pressure area that formed offshore the Mexican state of Oaxaca on June 16, 2021. The low steadily developed organized deep convection and a closed surface circulation, becoming Tropical Depression Four-E around 06:00 UTC June 18.[nb 1] The depression strengthened into a tropical storm nine hours later and was named Dolores. Gradually approaching the southwestern coast of Mexico, Dolores steadily intensified despite its close proximity to land. The storm reached its peak intensity around 15:00 UTC June 19 with maximum sustained winds of 115 km/h (70 mph) and a minimum barometric pressure of 29.2 inHg (989 mbar), just below hurricane strength. Shortly after reaching this intensity, Dolores made landfall just northwest of Punta San Telmo, near the ColimaMichoacán state border. The storm rapidly weakened as it moved inland over Mexico and dissipated early on June 20 over the state of Zacatecas.

The precursor disturbance to Dolores and the Atlantic's Tropical Storm Claudette caused several days of heavy rainfall across southern Mexico and Central America. Tropical storm watches and warnings, as well as a hurricane watch, were issued along the southwestern coast of Mexico shortly after Dolores' upgrade to a tropical storm, from Nayarit southeastward to Michoacán. At least three people died in Mexico due to the storm, with two of the deaths occurring in Guerrero and the third in Jalisco. Total damage across Mexico was estimated at USD$50 million.[nb 2]
