Hurricane Polo struck Mexico as a Category 3 storm, submerging streets, collapsing rooftops and forcing residents to clear debris, before tracking north and unleashing its remnants on the US Southwest. Widespread flooding fears are now gripping the region, with dam failure warnings added to already high water levels. The storm is the latest to strike during what forecasters describe as an active hurricane season.

Aerial footage from Mexico shows entire streets submerged, with several building roofs collapsing under the force of the storm's winds and rainfall.

Flood watches are now in place across parts of the US Southwest as Polo's remnants push further inland, compounding damage already caused in the region.

Dam failure fears mark an escalation beyond standard flood warnings, raising the prospect of catastrophic downstream flooding for communities in the storm's path.
