A hurricane hit the area in mid-September 1919. Tía Josefa and her family, as well as Tío Anastacio and his family, came to Anastacia's house for shelter. The wind was so strong that they braced heavy beams called vigas against the doors and walls. Men added their weight to the braces by leaning against them. Anastacia was nine years old and recalled two men raising her as she held a kitchen knife. They recited a special storm prayer:

"Jesucristo, aplaca tu ira, tu justicia y tu rigor, y con gran poder, misericordia Señor."

     "Jesus Christ, placate your anger, your justice, and your severity, and with great                                                  power, have mercy, Lord."

This prayer was repeated three times. Anastacia made the sign of the cross with the knife after each recitation, symbolically cutting the cloud. After a few hours, the wind died down, and no harm came of it.
