Update: 10:13AM SUPER Typhoon Maysak has slammed into the outlying islands of Federated States of Micronesia, packing sustained winds of 250 kilometres per hour.
Guam’s national weather service said the category five storm hit the atolls of Fais and Ulithi in Yap state last night, bringing heavy rain and hazardous storm surges to coastal areas.
It said the typhoon was now moving in a north-westerly direction away from Ulithi, but typhoon-force winds would likely remain until mid-morning on Wednesday.
There have been no reports of deaths in Yap state.
Super Typhoon Maysak is the third category five storm observed in the Western Pacific this year, according to meteorologist Jeff Masters of Weather Underground.
The islands in neighbouring Chuuk state – home to nearly 50,000 people – received a direct hit from the storm late on Sunday.
Five people were killed in Chuuk state, the Pacific News Centre in Guam said, quoting FSM public information officer Marz Akapito.
Robert Ruecho, the consul-general for FSM based in Guam, said he was aware of the reports of casualties but could not confirm the numbers.
Mr Ruecho told the Marianas Variety newspaper in Guam he had not been able to make contact with people because phone lines and power were down in Chuuk.
Maysak is forecast weaken significantly as it moves slowly towards the Philippines later this week.
The Joint Typhoon Warning Centre is predicting that Maysak will weaken to a Category 1 typhoon when it hits Luzon Island in the Philippines on Easter Sunday.
The Philippines is still recovering from Super Typhoon Haiyan, which struck in November 2013, leaving more than 7,350 people dead or missing.
