(CNN) - The National Weather Service Seattle is warning of a one-two punch of storms for the region, with the first storm arriving Friday.
The second storm, which is the stronger of the two, will pack the remnants of Typhoon Songda and strike the Pacific Northwest on Saturday with intense wind and rain.
Strong winds have already uprooted trees, toppled telephone poles and ruffled rooftops in the coastal Oregon town of Manzanita, where a tornado touched down Friday morning.
There is growing consensus that the Saturday storm will move over Washington, according to the weather service.
Oregon only averages two tornado touchdowns a year, and it has almost been two years since the Oregon office of the National Weather Service has issued a tornado warning, meteorologist said.
The weather service office in Portland, Oregon had issued at least 10 tornado warnings as of midday Friday. They have only issued 11 in the past 20 years, according to meteorologist Bryce Williams.
"Police are doing a great job keeping people safe after tornado," Manzanita resident Michael O'Loughlin tweeted.
If the storm crosses directly over or near western Washington, "this would be a worst-case scenario leading to a historical and destructive windstorm for the area," it had warned earlier this week.
The winds from the second storm are likely to be fierce and widespread, according to CNN Weather.
"Coastal Washington, Oregon and the interior mountain ranges will feel the brunt of the strongest winds, possibly reaching hurricane strength (which is 74+ mph) by Saturday evening," said CNN meteorologist, Derek Van Dam.
"Damaging winds will still be possible across the Seattle metro region, but will experience gusts between 50 to 60 miles per hour."
Seattle began hunkering down for the double barrel of storms, by shutting its parks, preparing emergency resources and opening more slots at its homeless shelters.
The possibility that the Saturday storm could be "one of the severest weather events that we've ever had has caused us to step up our response significantly," said Seattle Mayor Ed Murray in a press conference Thursday.
Rain pelted the northwest Thursday as the National Weather Service warned of high winds ranging from 30 to 70 mph. The winds on Thursday night reached 82 mph in Crystal Mountain and 48 mph in Hoquiam, Washington.
Saturday's storm is expected to drench Washington all the way down to northern California. It could pose dangers including falling trees, downed wires, power outages and floods.
The storms could produce high seas potentially reaching 30 feet or higher, and coastal flooding along areas of Washington, according to CNN Weather.
A third storm may pass through the Pacific Northwest next week, said CNN meteorologist Dave Hennen.
Record highs possible early next week
While this assembly line of storms will not directly impact the weather in north Alabama, it will impact the overall storm pattern over the country in the next seven days.
With deep troughing over the Pacific Northwest, a strong ridge of high pressure will develop across the southern Plains and Mid-South.
With a strong ridge controlling our weather early next week, record highs are possible in the Tennessee Valley. Afternoon highs may approach 90 degrees next Tuesday and Wednesday.
The latest 90-degree day on record in Huntsville is October 20.
