During the night of June 21, Cosme made landfall just east of Acapulco. It moved inland and quickly deteriorated, weakening into a tropical storm shortly after coming ashore.{{EPAC hurricane best track}} It trekked northward through eastern Mexico and further diminished into a tropical depression before becoming indistinguishable south of Brownsville, Texas on June 23. Tropical Storm Allison's development in the Gulf of Mexico was partially related to residual conditions from Cosme's remnants.
