Hurricane Polo Threatens Baja California Sur as Massive Pacific Storm Intensifies

Forecasters expect Hurricane Polo to make landfall on the Pacific coast of Baja California Sur on Monday night. At 11 a.m. EDT on Sunday the U.S. National Hurricane Center reported the storm about 200 mi off the Baja coast, moving north-northwest at 12 mph with sustained winds of 125 mph. AccuWeather projects Polo will weaken to a Category 1 before landfall but still pose a risk of toppling trees, downing power lines and causing structural damage. The system is forecast to dump 4–8 inches (10–20 cm) of rain across Baja California Sur, raising the threat of flash flooding and mudslides, and then to cross the Gulf of California toward Sonora and Chihuahua.

Polo underwent a rapid-intensification phase, climbing from a tropical depression to a Category 5 hurricane in 42 hours—the fastest on record in the Western Hemisphere. Its central pressure fell to 892 mb, the second-lowest ever observed in the eastern Pacific, and maximum sustained winds peaked at 180 mph. Meteorologists attribute the strengthening to an El Niño-driven marine heatwave that has elevated sea-surface temperatures across the central and eastern Pacific. Polo is the third Category 5 hurricane of the season in the eastern/central Pacific, joining Genevieve and Lowell.
