The earth's strongest storm this year is striking US territories in the western Pacific Ocean.

A strengthening Super Typhoon Yutu, with sustained winds of 290km/h, is on a trek through the Northern Mariana Islands.

The storm is roaring across the islands of Saipan and Tinian, both US territories, and will become one of the most intense storms - if not the most - on record to hit the US.

Meteorologist Brandon Aydlett says the US National Weather Service has received reports Yutu's catastrophic winds ripped roofs from houses and blew out windows.
