Hurricane Polo to make life‑threatening landfall off Mexico Coast; El Niño?

Hurricane Polo is set to strike Baja California Sur later on Monday, 28 September 2026, as a Category 3 storm with sustained winds of 125 mph. The United States National Hurricane Center (NHC) noted that the eye sits roughly 320 km off the coast, moving north‑northwest at 19 km h⁻¹.

The NHC warns that the storm could trigger life‑threatening flooding and mudslides in the steep terrain of the region. A Category 3 hurricane can still topple trees and power lines, and the NHC has cautioned that even a weaker storm could cause structural damage.

Hawaii and Mexico brace for ‘life-threatening flooding’ from Pacific hurricanes

El Niño, a climate pattern that warms the central and eastern Pacific, is cited by several meteorological agencies as a factor fueling Polo’s intensity. The pattern creates low wind shear and warm sea‑surface temperatures that can support hurricane development. While El Niño is not the sole determinant of a storm’s strength, it often creates favorable conditions for tropical cyclones in the eastern Pacific.

Impact in Mexico

Authorities in Mexico have mobilised a large emergency response. The Mexican Navy and Defence Ministry deployed about 7,000 personnel to Baja California Sur and opened 169 shelters for residents. Schools and beaches in Cabo San Lucas and San José del Cabo have been closed, and port closures have been announced along the coast. The NHC and Mexican authorities warned residents to stay indoors and avoid low‑lying areas.

Casualties have already been reported. Two minors were killed in Jalisco when their home was swept downstream, and their parents remain missing. The state Civil Protection and Fire Department confirmed the incident.

In San Juanico, a small fishing community on Baja’s Pacific coast, fishermen have boarded up homes and raised concerns that the storm’s waves could breach earthen barriers. A local fisherman, Rocío Sánchez, said that the current tides and expected waves could give way to the barrier, creating a high‑risk area for flooding.

Besides the immediate threat to Baja California, Polo is forecast to bring heavy rain to parts of the U.S. Southwest later in the week. The NHC predicts that the system could produce significant rainfall as it moves eastward, potentially affecting Arizona, New Mexico, and Colorado. The forecast includes up to 30 cm of rain in Baja California Sur, with the potential for 10–20 cm across Baja California.

As Polo approaches, the Mexican navy gathered personnel and humanitarian aid in the ports of Guaymas and Mazatlán. Three vessels have been deployed to deliver aid to coastal communities that may become isolated by the storm.

Impact in Hawaii

Across the Pacific, Hurricane Nolo is pulling away from Hawaii, yet its outer bands still pose a risk of heavy rain and flooding on the islands. Nolo’s maximum sustained winds have climbed to near 105 mph, and the National Weather Service warned of up to 20 inches of rain on the Big Island.

Hawaii’s governor issued an emergency proclamation, activating more than 120 members of the state National Guard, and the federal government authorized the Federal Emergency Management Agency to coordinate assistance and provide funding support.

Southern California Surf

The L.A. Times reported that the high surf generated by Polo and the nearby Hurricane Odalys will reach Southern California. Four‑to‑seven‑foot waves are forecast for Los Angeles and Ventura counties, with strong rip currents and possible coastal flooding. The National Weather Service issued a coastal flood advisory for the region from Monday through Wednesday.

Looking Ahead

The storm’s projected path takes it across Baja California and into the mainland, where it could affect Sonora and Chihuahua. The NHC forecast for the next 48 hours includes a potential for the storm to weaken to Category 1 before landfall, but the rainfall threat remains significant.

The NHC and Mexican authorities urge the public to monitor local weather updates and remain aware of the evolving storm path.
