Guam residents stock up, batten down as dangerous Super ...

HONOLULU -- President Joe Biden approved an emergency declaration as an intensifying Super Typhoon Mawar approached Guam, where anyone not living in a concrete house was urged to seek safety elsewhere and emergency shelters began to fill ahead of what could be the most powerful storm to hit the U.S. Pacific territory in two decades.

Gov. Lou Leon Guerrero said on social media that the declaration will support the mobilization of resources into Guam, which is “especially crucial given our distance from the continental U.S.” Guerrero ordered residents of coastal, low-lying and flood-prone areas of the territory of over 150,000 people to evacuate to higher elevations.

Federal assistance will be needed to save lives and property and "mitigate the effects of this imminent catastrophe,” Guerrero said in a letter to the president requesting a “pre-landfall emergency” for Guam. Officials warned residents who aren’t in fully concrete structures — many homes on the far-flung island are made of wood and tin — to consider moving.

With rain from the storm’s outer bands already falling on the territory, National Weather Service said the storm had been upgraded to a Category 4 “super typhoon,” meaning maximum sustained winds of 150 mph (241 kph) or greater. Its center was about 140 miles (225 kilometers) southeast of Guam late Tuesday local time and was moving to the north-northwest, according to the weather service.

The weather service said the storm was intensifying and warned of a “triple threat” of winds, torrential rains and life-threatening storm surge on Guam. The weather service said the storm could hit southern Guam around midday Wednesday, which is Tuesday evening in the mainland United States. Guam lies west of the International Date Line and is a day ahead of the mainland and Hawaii, which is 3,800 miles (6,115 kilometers) to the east. Manila, Philippines, is 1,600 miles (1,575 kilometers) to the west.

If Guam doesn’t take a direct hit, it will be very close, said Patrick Doll, the lead weather service meteorologist in Tiyan, Guam.

Guerrero urged residents in a YouTube message to remain calm and ordered the National Guard to help those in low-lying areas evacuate as residents stocked up on water and generators.

“We are at the crosshairs of Typhoon Mawar," she said. "Take action now, stay calm, stay informed and stay safe.”

A storm surge of 6 to 10 feet (2 to 3 meters) above the normal high tide was expected and could reach as high as 15 feet (4 1/2 meters). Surf was expected to build sharply in the next day or two along south- and east-facing reefs, with dangerous surf of 20 to 25 feet (6 to 7 1/2 meters) into Wednesday, the weather service said.

The storm is moving at only 5 mph (8 kph) but has an eye 17 miles (27 kilometers) wide, meaning people at the typhoon's center could see calm conditions for over three hours and conclude, far too soon, that the worst is over, Doll said. As the eye leaves, the winds could rise to 150 mph (241 kph) in minutes, so people should remain sheltered until the government gives the all-clear, he said.

“Folks may say, ‘Hey it’s over, we could go outside and start cleaning up,’” Doll said. “That is totally wrong.”

Guam resident Albert Eliasson told KUAM News he is stocking up and battening down, including making sure to have enough water to drink and flush toilets.

“Just making sure that we have things prepared, shutters on the windows that need it,” he said.

Oshean Saralu told KUAM he is also doing everything he can to prepare for a direct hit. “We usually pack everything up for most of our stuff inside our garage and just secure everything, especially the windows,” he told KUAM.

At the island’s grocery and hardware stores Monday, people left with shopping carts full of canned goods, cases of water and generators, the Pacific Daily News reported.

Rota, an island in the U.S. Commonwealth of the Northern Mariana Islands, was also under a typhoon warning, Doll said. Tinian and Saipan, in the Northern Marianas, were under tropical storm warnings.

Some people in those areas are still in temporary shelters or tents after Category 5 Super Typhoon Yutu in 2018, Doll noted.

“Guam takes a Category 4 or 5 hit every five to seven years. Mother Nature has spared us as of late,” Doll said, adding that the last direct hit was in 2002. “So we are way overdue.”

Typhoon season runs from July 1 to Dec. 15 in the western North Pacific, according to the weather service.
