The Northern Marianas governor Eloy Inos has suspended work for non-critical government personnel on Saipan and Tinian, and school classes on the two islands are also cancelled as Typhoon Champi moves closer to the CNMI.
The National Weather Station in Guam has now raised Typhoon Condition 1 for the Northern Marianas islands of Agrihan, Pagan, and Alamagan, which means that destructive winds of 119 kilometres per hour or higher are expected within 12 hours.
Saipan and Tinian may experience winds of 32 kilometres per hour or greater within 12 hours. A flash flood warning has also been raised on Saipan and Tinian.
A Tropical Storm warning, meanwhile, has been issued for the island of Rota.
The National Weather Station says at 5am local time in the CNMI, Champi was tracked moving west at 28 kilometres an hour.
