Hold onto your hats and grab your jackets, folks! Here’s the latest weather scoop from the National Weather Service Seattle, as reported by Grays Harbor County Emergency Management.
Wind alert:
A High Wind Warning is still in effect. It started at 1 p.m. Monday and was forecast to last until 10 a.m. Tuesday. Grays Harbor could see 45 to 50 mph winds and gusts up to 60 mph.
If that wasn’t enough, this warning was expanded Monday and now covers all lowland portions of Grays Harbor County, including East County.
At 2:16 p.m. Monday, gusts to 64 mph on the Astoria Bridge were reported.
Flood watch:
As the rain continues to pour, Grays Harbor County Emergency Management is keeping a close eye on our rivers. The flood watch is still in effect until Tuesday afternoon, as the heavy rainfall keeps pushing local rivers up. Looks like many of the rivers will stay below minor flood stage.
Surf’s up:
A High Surf Advisory Through 4 p.m. Tuesday. Expect large waves between 15 and 25 feet crashing in the surf zone. If you’re heading to the coast, never turn your back on the ocean.
The Northwest is facing yet another storm early this week that will bring a swath of heavy rain, wind and mountain snow. Forecasters highlight the risk for river flooding, avalanches and mudslides will remain high.
A tumultuous weather pattern will continue to focus across the Northwest U.S. into early week, AccuWeather experts warn. After one atmospheric river funneled moisture into Washington, another storm pushing into the region at the start of the workweek will channel another round of flooding rain, wind and high-elevation snowfall.
Communities along the Washington and Oregon coastline observed upwards of 2-4 inches of rain from Saturday into Sunday night as the first storm advanced into the region. Forecasters highlight that additional rain is on the way as a secondary storm intensifies and pushes onto the coast.
Some locations along the Northwest coast are on track to observe more rain in a two-day period than they have observed so far this month.
“The Pacific Northwest is not getting a chance to breathe amid this active atmospheric river pattern. The advancing storm has strengthened rapidly offshore and will be spreading yet more rain to the already soaked region,” explained AccuWeather Meteorologist Jacob Hinson.
“By the time the early week storm is done, total rainfall will rise to 3-8 inches from both storms in lower areas and greater than 16 inches in mountainous terrain. As a result, concerns for river flooding remains high, especially with the previous week’s snow melting and contributing to runoff,” added Hinson.
In addition to downpours impacting the coastal and foothill regions, forecasters also are highlighting a considerable danger for avalanches across the Washington Cascades over the upcoming days. The rounds of heavy rain soaking sloped areas weakly packed with snowfall could rapidly create a risk for avalanches from the upper elevations to the valley floors, and hikers are discouraged from venturing out given the stormy circumstances.
“In the foothills of the Cascades, fresh rainfall totals can surpass 2 inches by Monday evening before the changeover to snow occurs between 3,000-4,000 feet. Snow levels will fall throughout the day on Monday before rising again on Tuesday, with Monday night providing the best chance for snow in the lower passes, like Snoqualmie Pass,” noted AccuWeather Meteorologist Emma Belscher.
As the storm intensified and pummeled into the Northwest Coast on Monday, AccuWeather meteorologists warned that an atmospheric phenomenon called a “sting jet” can occur.
A meteorological term that has been growing in popularity in the United Kingdom since the early 2000s, a “sting jet” is a small area of intense winds that can develop underneath low pressure systems, causing extensive wind damage. The formation looks like a bee’s stinger or scorpion’s tail on weather satellites, while “jet” is short for jet stream, a corridor of high winds high in the atmosphere.
“As this low pressure system rapidly strengthens, it will bring very strong wind gusts that parallel the coasts. We’re expecting gusts of 60-80 mph along the coast, locations just inland and along the mountaintops. More sheltered cities like Seattle can observe gusts around 40-60 mph,” noted Hinson.
Hinson added that the highest gusts will likely be along the border between Washington and Oregon, where a possible sting jet could increase winds even further. Wind damage is likely during this event, with power outages and downed trees being the most common through Tuesday morning.
By Tuesday afternoon and evening, the storminess is expected to wane across the Northwest. Gusty winds will taper off and rain will cease across the region, leaving most locations dry through the remainder of the workweek.
