Alaska’s western coast is expecting high winds and flooding in powerful storm this weekend

By Chuck Johnston and Aya Elamroussi, CNN

The remnants of Typhoon Merbok are putting residents of western Alaska on high alert as a coastal storm is expected to bring flooding and strong winds this weekend.

Wind gusts as high as 65 mph are expected for Kotzebue Sound and Chukchi Coast, according to the National Weather Service in Fairbanks. Winds are scheduled to peak early on Saturday morning.

Forecasters call it “the strongest storm in over a decade.”

Officials in the Nome area, with about 10,000 residents, have urged people to prepare.

“Port users should secure boats and vessels in the harbor and on Belmont Point. Please check your lines and gear periodically to avoid losses,” the town of Nome said on its Facebook page.

The town said its recreation center will serve as the emergency shelter.

“The many local, state, federal, tribal, and non-government agencies and emergency response organizations are aware of this storm’s potential and are preparing their response capabilities,” the Alaska Division of Homeland Security said. “The State Emergency Operation Center staff will continue to monitor the situation and communicate with communities in the path of the storm.”

The Alaska Department of Transportation and Public Facilities asked people to report road conditions to its Nome maintenance station.

The system was moving over the Bering Sea, which spans the northern Pacific Ocean between Alaska and Russia.

“This is a dangerous storm that is expected to produce widespread coastal flooding south of the Bering Strait with water levels approaching levels not seen in nearly 50 years,” the weather service warned Thursday.

Along Alaska’s shore, the main threats are a double-whammy of coastal flooding and winds up to 60 mph with higher gusts that could displace loose objects, damage buildings and bring down powerlines.

Weather officials in Alaska also urged residents to prepare for the storm as it could threaten to overwhelm critical infrastructure and wash away roads. The storm’s impacts are expected Friday through Sunday morning, with water levels rising the highest Saturday.

Coastal flood watches have also been issued for all coastlines along the west coast of Alaska between just north of the Arctic Circle down through the Kuskokwim Delta coast.

The last time Alaska saw a storm this strong was in 2011, when it left behind a wide swath of destruction. Like Merbok, the 2011 system was an extratropical storm. An extratropical storm or cyclone has cold air at its core — unlike a tropical storm or cyclone which has a warm core. Both can cause significant damage from strong winds, heavy rain and storm surge.

“When a big storm comes in, we always say, ‘Does it compare to the 2011 storm?'” Jonathan Chriest, a meteorologist with the weather service in Fairbanks, told CNN. “This is the first storm since 2011 that we have high confidence … will compare impact-wise.”

On Friday, the remnants of Merbok are forecast to move into the Bering Sea and “bomb out” in a process also known as bombogenesis, referring to a pressure drop of 24 millibars in 24 hours or less. That means the storm is rapidly strengthening and has the potential to cause significant damage.

“Winds will peak early Saturday morning near Shishmaref, and during the day Saturday near Kotzebue and the Chukchi Coast,” the weather service said. “Coastal flooding will occur, in addition to significant beach erosion.”

While most areas will see around 1 inch of rain with this storm, some could pick up as much as 3 inches through the weekend.

Even if Anchorage — more than 500 miles from Nome — picks up 1 to 2 inches from this storm, it will push this year into the top five wettest years on record.
