Overview
- Hurricane Polo reached Category 5 intensity on Tuesday with reconnaissance reporting sustained winds near 160–180 mph and a very low central pressure around 892 mb.
- The National Hurricane Center says Polo is expected to stay offshore of southwestern Mexico over the next few days while producing torrential rain that could cause life‑threatening flooding and mudslides in Guerrero and Michoacán.
- Mexican authorities have issued tropical‑storm watches, closed ports, suspended classes and opened shelters as coastal communities brace for heavy rain, high surf and dangerous rip currents.
- Forecasters warn that interaction with nearby Tropical Storm Odalys and complex steering currents make Polo’s weekend track uncertain, leaving the Baja peninsula, Southern California and the U.S. Southwest at risk of large swells or a surge of tropical moisture depending on how the storms evolve.
- Scientists say Polo’s extreme rapid intensification was driven by very warm sea temperatures and low wind shear tied to the strong El Niño this year, and the NHC will review reconnaissance data to confirm how Polo ranks against past eastern Pacific records.
