Calvin was a short-lived tropical storm that made landfall near Paja Blanca, Mexico. Heavy rainfall associated with Calvin caused flash flooding and mud slides that resulted in some damage in southern Mexico.

A tropical depression formed by 12:00 UTC on June 11 while located about 150 mi (240 km) south-southeast of Salina Cruz, Mexico.
By 18:00 UTC on June 12, the tropical depression intensified into Tropical Storm Calvin. Intensifying slightly to reach winds of 45 mph (75 km/h), Calvin made landfall near Paja Blanca, Mexico, halfway between Salina Cruz and Puerto Ángel, around 00:00 UTC on June 13. Calvin dissipated into a remnant low, which brought heavy rainfall and some flooding in the area. Even though the cyclone dissipated, heavy rains associated with its mid-level remnants continued for about another 24 hours over the southern and southwestern portions of Mexico.

The main hazard associated with Calvin was heavy rainfall. The tropical storm produced a widespread area of 5 to 10 inches of rainfall across the Mexican states of Oaxaca, Tabasco, and Chiapas during the period of 11-13 June. The heaviest rains occurred near Salina Cruz, where almost 15 inches was reported. After Calvin dissipated, its remnants moved westward and caused heavy rains over the state of Guerrero on 13-14 June that resulted in totals of about 5 inches.

There were no reports of casualties associated with Calvin.
Heavy rains associated with the tropical storm flooded portions of the state of Oaxaca, where the ground was saturated about 10 days earlier due to Tropical Storm Beatriz. The episodes of heavy rains from both Beatriz and Calvin damaged roads and caused some towns to be evacuated in Oaxaca.
