Hurricane Polo hits Baja California as Category 3 storm, kills 3
Hurricane Polo made landfall in Baja California Sur on September 28 as a Category 3 hurricane with 185 km/h winds, causing severe flooding, mudslides, and at least three deaths. Mexican authorities evacuated residents, set up 169 shelters, and deployed nearly 7,000 military personnel. The storm's rapid intensification was linked to strong El Niño warming.

Hurricane Polo made landfall on Mexico's Baja California Sur peninsula late on September 28 as a Category 3 hurricane with sustained winds of 185 km/h (115 mph) and gusts up to 220 km/h. The storm brought torrential rainfall, severe flooding, and mudslides across the region. At least three deaths were reported—two children whose home was swept away in Jalisco state and a young woman caught in strong currents near Puerto Vallarta.
The hurricane rapidly intensified before landfall, evolving from a tropical depression to a Category 5 storm in approximately 42 hours—the fastest such intensification recorded in the region since 1970. Meteorologists attributed the unusual intensity to a strong El Niño warming the Pacific waters. As Polo moved northwestward toward cooler waters, it weakened to Category 3 by the time it reached Baja California Sur.
In Puerto San Carlos, a fishing town of about 5,700–6,000 residents, storm surge breached protective earthen barriers and flooded coastal streets before the official landfall. Residents evacuated to shelters in Ciudad Constitución, approximately 60 kilometers away. Mexican authorities established 169 temporary shelters with capacity for over 33,000 people and deployed nearly 7,000 military personnel to assist with emergency response. Schools, ports, and beaches were closed; travel was suspended in the hurricane's path.
Rainfall totals were forecast at 150–300 millimeters across parts of Baja California Sur, with accumulations of 100–200 millimeters expected in Sonora and Sinaloa. The storm threatened dangerous storm surge, large destructive waves, and life-threatening flash floods and mudslides. After crossing Baja California Sur, Polo was expected to weaken as it crossed the Gulf of California and moved into mainland Mexico on September 29. The National Hurricane Center warned of impacts extending to parts of the southwestern United States later in the week, where saturated soils from recent heavy rains increased flood risk in Arizona, Utah, New Mexico, and Texas.
Why This Matters
Hurricane Polo's Category 3 landfall on September 28 in Baja California Sur directly affects coastal infrastructure, fishing economies, and transportation. At least three deaths, flooding across multiple Mexican states, and potential cross-border impacts to southwestern U.S. states create immediate humanitarian and supply-chain risks. The 42-hour intensification from tropical depression to Category 5 represents an anomalous weather pattern linked to El Niño sea-surface warming, signaling potential future storm behavior changes in the Pacific basin. Mexican emergency deployment of 169 shelters and 7,000 personnel indicates substantial resource commitment; rainfall forecasts of 150–300 mm create sustained flood and mudslide risk in Sonora, Sinaloa, and the southwestern U.S., where soil saturation from prior rainfall amplifies vulnerability.
