Heavy rains caused by Hurricane Ida have killed at least 50 people and left several others missing in El Salvador, civil protection officials said Sunday.

Officials readied storm shelters along Mexico’s Caribbean coast Saturday and told fishermen and tour operators to pull in their boats amid warnings that Tropical Storm Ida could become a hurricane as it neared the resort city of Cancun.

A fisherman was reported dead, swept away by a wave, as Tropical Storm Andres drenched western Mexico on Tuesday and threatened to become the first hurricane of the eastern Pacific season.
