Hurricane Polo Becomes Pacific’s Strongest Category 5 Storm Overnight
Hurricane Polo is a very powerful storm in the eastern Pacific Ocean.
It quickly became a Category 5 hurricane, the strongest category used for hurricanes.
Its winds are reaching about 265 kilometres per hour.
The storm is moving very slowly, so it can pull a lot of water and bring heavy rain.
It is near Mexico but may not make landfall.
Forecasters are unsure whether it will stop, loop around or move toward northwestern Mexico.
Mexico has closed some ports and suspended classes in several areas.
People near the coast have been warned about rough seas, floods and mudslides.
Hurricane Polo rapidly intensified into an extremely dangerous Category 5 storm with 265 kmph winds.
The storm is about 338 kilometres south of Zihuatanejo and may brush Mexico’s southwestern coast.
Polo’s nearly stationary movement could produce heavy rain, flash floods, mudslides and dangerous seas.
Forecast models disagree on whether Polo will stall, loop or move across northwestern Mexico.
The storm’s rapid strengthening occurred as Pacific ocean temperatures reached 3.05 degrees Celsius above average.
