Pago Pago, AMERICAN SAMOA — Guamanians are being urged to continue sheltering in place as Typhoon Sinlaku slowly tracks away from the neighboring Northern Mariana Islands, according to the latest AP report.

The US National Weather Service in Guam says typhoon Sinlaku is weakening as it slowly moves away from Saipan and Tinan in the CNMI.

Despite the storm weakening residents in Guam on Wednesday evening were still being warned to continue sheltering in place as the slow moving storm's effects continued to be felt across Guam and the CNMI.

Jenna Blas stationed in a concrete bunker in Guam with the Joint Information Warning Centre says Guam remains in condition readiness one, the highest alert level, and everyone is to remain indoors until the all clear is given.

"So at this time we are still expecting some of those extended peak conditions from this really slow moving Typhoon Sinlaku, Jenna Blas said.

"We are still expecting to experience damaging winds of 39 miles per hour or more and really continuing well into this evening.

Ms Blas said the Guam Governor Lou Leon Guerrero has declared that Guam will remain at the highest alert level through the evening to ensure public safety and allow for emergency responders to conduct essential assessments.

Typhoon Siniaku was classified as a super typhoon, with it being the strongest tropical cyclone on Earth this year, the NWS said.
