Hurricane Polo, described as a large and 'very powerful' storm, was downgraded slightly but remains a major threat off the Pacific coast of Mexico. Meteorologists attribute the storm's rapid intensification to unusually warm waters linked to the El Niño weather phenomenon, potentially making it one of the most powerful storms of the Pacific hurricane season. BBC meteorologist Courtney Sargent explained how El Niño conditions may have fueled Polo's rapid strengthening, raising concerns about its potential impact on coastal areas.
