Hurricane Polo made landfall in Baja California on September 29, bringing flooding, toppled trees and heavy rainfall to coastal communities in Mexico. The storm came ashore as a Category 1 hurricane and is expected to weaken as it moves north-northeast over land.

Forecasters warned that Polo's moisture will push into the southwestern United States, with Arizona and New Mexico facing heavy rainfall, flash-flood risks and gusty winds in the coming days. Spaghetti models showed the system's remnants tracking northward through inland Mexico before crossing into the US desert southwest.

Authorities in affected Mexican states urged residents in low-lying areas to stay alert for flooding and landslides. The storm adds to an active Pacific hurricane season that has repeatedly threatened Mexico's Pacific coast this year, with emergency services placed on standby along Polo's projected path. Emergency management officials in both countries are coordinating on relief, while meteorologists caution that remnant moisture could disrupt travel and outdoor events across the desert southwest through the weekend.
