Hurricane Polo continues to churn in the Pacific, with its path expected to impact both Mexico and the southwestern United States.
Why it matters: Hurricane Polo is a powerful storm with sustained winds of 180 mph, posing risks to coastal areas and bringing changes in weather patterns to Southern California and Arizona.
As of September 25, 2026, Hurricane Polo was located near Mexico and was predicted to make landfall between Monday and Tuesday.
The storm is anticipated to bring increased surf and humidity to Southern California, along with dangerous rip currents and coastal erosion.
In Arizona, tropical moisture from Polo is expected to create thunderstorms and cooler temperatures early next week.
Driving the news: Hurricane Polo has gained strength, prompting local authorities in Mexico to prepare for its arrival. As the storm approaches, ports have been closed, and shelters are being set up along the Baja California Peninsula.
Forecast models indicate that Polo's outer bands will bring some light rain and drizzle to San Diego County on Sunday, September 27, and possibly linger into Monday.
Local officials in Mexico reported no major damage or flooding as of Friday, but preparations are underway as the storm's impact hangs.
The National Hurricane Center confirmed that the hurricane is tracking north-northwest before curving east toward Mexico.
State of play: The effects of Hurricane Polo are already being felt in Southern California, where beach hazard statements have been issued due to increased surf.
Coastal areas are under alert for dangerous rip currents and potential erosion through Sunday evening.
The Southland can expect humidity levels to rise significantly as Polo's moisture reaches the region, though heavy rainfall is not anticipated.
In Phoenix, temperatures are forecast to rise to around 100 degrees on Saturday, September 26, before dropping slightly ahead of the tropical moisture.
The big picture: As Hurricane Polo approaches, the Southwest is bracing for a shift in weather patterns.
Moisture from both Hurricane Polo and another system, Odalys, is expected to arrive in Arizona by Sunday, September 27, bringing cooler temperatures and cloudy skies.
Strong thunderstorms are anticipated in Arizona's high terrain on Monday and Tuesday, September 28-29, with potential heavy rain.
After the tropical moisture passes, conditions are expected to dry out, leading to warmer weather later in the week.
What they're saying: Local officials and meteorologists are urging residents to stay informed and prepared as Hurricane Polo approaches.
"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding," said Captain Ashley Losch of the Glendale Fire Department.
Authorities recommend that residents prepare emergency kits and stay updated on weather conditions as the storm approaches.
In Mexico, officials are on high alert and have mobilized resources to assist those in need as the hurricane nears landfall.
