Hurricane Polo tore into Mexico's Baja California Sur on Sunday as a Category 3 storm, packing 115 mph winds before churning toward mainland Sonora, where officials warned of life-threatening flooding and mudslides. Coastal communities, many already stretched thin on emergency resources, braced for the storm's second landfall as forecasters tracked its path inland.
The storm arrives amid a stretch of increasingly intense hurricane seasons across the Pacific, a pattern scientists have long linked to warming ocean temperatures fueling stronger, wetter storms. Residents in flood-prone low-income neighborhoods face the greatest risk from mudslides and infrastructure failures, underscoring the uneven toll extreme weather takes on communities with the fewest resources to prepare or recover.
Mexican emergency officials mobilized shelters and response teams ahead of the storm's advance, though the scale of Polo's rainfall raised concerns about whether existing infrastructure can withstand the flooding. As the storm pushes into Sonora, attention is turning to how quickly aid reaches the hardest-hit areas and what the storm reveals about regional preparedness for a warming climate's escalating hazards.
