Typhoon “Mawar” has made its closest point of approach to Guam, with most of its eye passing through the Rota Channel between Guam and Rota. Its southern eyewall, however, grazed the northern tip of the island, near Anderson Air Force Base.

The typhoon caused widespread power cuts, affecting 98% of Guam Power Authority customers, and a major internet outage.

Landon Aydlett, a National Weather Service meteorologist in Guam, said Mawar’s winds were so fierce that the building the weather service office is in was vibrating.

“This is an extremely dangerous and life-threatening situation,” he said. “There will be a swath of tornado-like damage.”

As Mawar moves away from the islands, the conditions will improve and damage assessments begin.

After moving away from Guam, Mawar is expected to peak at Category 5 Super Typhoon strength in the Philippine Sea, before it weakens near northern Philippines, Taiwan, and southern Japan (Ryukyu Islands).
