President Donald Trump is declaring an emergency for the Commonwealth of the Northern Mariana Islands and ordering the USA government to help local authorities respond to a typhoon.
The Weather Channel described this escalation as the "most explosive rapid intensifications of any tropical cyclone on record anywhere on Earth".
The Joint Typhoon Warning Centre (JTWC) said in their latest advisory that Hagibis now has maximum sustained wind speeds of about 150mph. "Which is almost three times what is needed to be considered rapid intensification".
"That means Hagibis intensified from a tropical storm to a Category 5 equivalent in just 24 hours", according to the Weather Channel.
High waves could occur from October 11 on the Pacific Ocean side of western and eastern Japan. This is the most intensification by a tropical cyclone in the western North Pacific in 18 hours since Yates in 1996 also intensified by 90 mph in 18 hours.
The U.S. Joint Typhoon Warning Center estimates the eye of Hagibis to be about 5 miles in diameter.
The areas are expected to see coastal flooding, according to the Weather Channel.
The extremely large Typhoon Hagibis is gaining force over the Pacific south of Japan and is forecast to approach the main islands of Kyushu, Shikoku and Honshu during the upcoming three-day weekend, the Meteorological Agency said. The Irish rugby team is set to face off against the Japanese team in the city of Fukuoka on the island of Kyushu this Saturday, according to the Guardian, but may have to move the location of the game because the island is now in the path of the typhoon. They say the location of Super Typhoon Hagibis could change and will need to be watched closely in the coming days.
As of Tuesday morning, Hagibis was moving over the Mariana Islands on a west-northwesterly track, the agency said.
