NOAA Hurricane Hunters and NHC Advisory 9 stamped Hurricane Polo as an extremely dangerous Category 5 with 180 mph sustained winds and 892 mb pressure on Tuesday; by Wednesday afternoon Intermediate Advisory 12A had Polo downgraded to Category 4 at 145 mph — still a very powerful major hurricane skirting southwestern Mexico with life-threatening flooding and mudslide risk, while President Claudia Sheinbaum said no direct landfall was expected.

NHC Intermediate Public Advisory Number 12A · 1800 UTC Wed Sep 23 2026

Note

On Tuesday afternoon, the National Hurricane Center’s Advisory 9 stamped Hurricane Polo Category 5: 180 mph sustained winds, 892 millibars, an NOAA Hurricane Hunter fix south of Zihuatanejo. The bulletin called it an extremely dangerous Category 5 expected to stay that way for a couple of days.

By Wednesday afternoon, Intermediate Public Advisory 12A had stepped Polo down to Category 4 — 145 mph, 931 mb — centered near 15.6 north, 102.1 west, about 150 miles south-southwest of Zihuatanejo and drifting northwest at 5 mph. NHC still calls it a very powerful major hurricane. Tropical storm warnings cover Tecpan de Galeana to Punta San Telmo; a watch runs west to Playa Perula. Forecast rainfall is 4 to 6 inches along coastal Guerrero, isolated 8, and 2 to 4 inches into Michoacán, Colima, and Jalisco — with life-threatening flooding and mudslides in steep terrain. The core is expected near the southwestern Mexico coast for the next day or two but forecast to remain offshore. Mexico’s President Claudia Sheinbaum said Tuesday that information so far pointed to no direct landfall, while urging vigilance in Jalisco, Colima, and Michoacán. Next full NHC advisory and any track change stay on the HUD.

Why it matters

A storm that leapt to Category 5 at 180 mph and 892 mb on Tuesday is still a major Category 4 off a populated Mexican coast Wednesday — intensity history plus flood and mudslide risk, not a carnival landfall call. Official track keeps the core offshore; the rain bands do not.
