The combined effects of Debby and Hurricane Kristy, which impacted Mexico's Pacific coast around the same time, rendered about 50,000 people homeless. Emergency crews worked to provide shelter for those left homeless. Relief supplies were delivered by boat to towns isolated by floodwaters. Local health officials in Mexico City warned of the possibility of outbreaks of hepatitis, typhoid, and other waterborne diseases. In response to the threat, homes located in the northern portions of the city near the Río de los Remedios were fumigated.
