• Hurricane Polo made landfall in Baja California Sur and later in Sonora, Mexico.
• Over 30 million people in the U.S. Southwest are at risk for flash flooding.
• The storm’s remnants are expected to bring significant rain to U.S. states from Arizona to Iowa.
• No casualties reported in Mexico, but significant flooding and road issues occurred.
• Hurricane Polo's winds peaked at 180 mph before being downgraded to a tropical storm.

Hurricane Polo made landfall on Mexico's Baja California Sur early Tuesday, impacting the region with powerful winds and rain. The storm's maximum sustained winds were reported at 110 mph as it lashed coastal communities, causing flooding and toppled trees. By mid-morning, Polo had weakened to a Category 1 hurricane but continued to present a flood risk as it moved northward into Sonora, evacuating residents in several municipalities. Fortunately, no fatalities were reported, and Governor Víctor Castro noted that there was “rain, but no loss of life” due to the hurricane's passage, according to Los Angeles Times and Reuters.

The National Hurricane Center forecasts that the remnants of Hurricane Polo will pose a significant flash flood threat across the southwestern United States, with warnings in effect across regions from Phoenix, Arizona to Des Moines, Iowa. Rain rates of up to two inches per hour are anticipated, particularly affecting areas in New Mexico and Texas. The NHC predicts that Polo's winds will still reach up to 35 mph when it approaches El Paso, Texas, highlighting a potential for severe flooding as it moves northeastward, according to CBS News and CBS News.

Before weakening as it moved inland, Hurricane Polo fluctuated in intensity, previously reaching Category 4 and even Category 5 levels. The storm underwent extreme rapid intensification, with wind speeds surging from 45 mph to 150 mph in just 24 hours, an event the NHC described as “truly remarkable.” Such activity has been attributed, in part, to unusually warm waters and strong El Niño conditions in the Pacific that are increasing tropical cyclone activity, as stated in reports from Los Angeles Times and Reuters.
