At 16:55, Portland reported S 25 mph gusting 38 with a peak gust of 40 at 15:17, and Salem showed S 29 mph gusting 39, with a peak gust of 46 at 16:32. Dorothy Reed University of Washington Civil Engineering and presented at the 12th Americas Conference on Wind Engineering in 2013, where it was included in the proceedings. The front is slow-moving, and it usually takes extra time for the cold air around the mouth of the Columbia Gorge to erode out, as, I suspect, the cold pool is usually deeper here. A house was reported destroyed by falling trees there, and areas of swathing were also noted. Heavy wind gusts buffeted me in the warm, 56.
Wind-wise, this was the most powerful storm for the Seattle Area since the January 20, 1993. Figure 32: The kind of three-post sign depicted below didn't do very well in the gale. This is a reflection of extreme pressure gradients associated with this storm, the details of which are discussed below in the caption for Table 2. A western redcedar toppled, and a Pacific madrone lost is top, among damage to a number of other trees, including the loss of very large branches from some. It had been ranging from 12 to 14 mph earlier. Current forecasts are for high winds on the west coast, reaching storm force in Ostrobothnia, while gusts over open seas could exceed 20 metres per second.
Several of these trees were simply shattered by the wind, and their impact with the ground. Perhaps a gradient like that seen on October 2, 1967 +13. Muddy water filled the Willamette River up to its banks. Intense rainfall accompanied this cyclone as the leading warm front, fed with copious tropical moisture, swept into the Pacific Northwest. Ultimately, what the maximum pessure gradient data in Table 2 reveal is that the focus of this event was in Western Washington, with the effects diminishing southward. Winds at 18:25 were S 36 mph gusting 52.
This tree clearly had a pathological condition that weakened the stem, evidenced by the dark, rotten wood in the lower left of the photo. With the lull in the wind, it seems like a good time for her to come home. It was described as the worst storm to hit the region since the Inauguration Day storm of January 20, 1993. By Saturday, Puget Sound Energy had 250 crews in the field. It is interesting that peak gusts at the Renton Airport, 51 mph, Boeing Field, 56 mph, and at the University of Washington, 55 mph, are far below those measured at the Sea-Tac Airport. Residents of the west coast can expect gusty winds that could also strike a blow to plans to set off fireworks in the Ostrobothnia region, according to local emergency services.
Air traffic in and out of Sea-Tac International Airport had to be curtailed when power to a critical radar system failed. The name of the storm was chosen in a contest run by the office in from about 8,000 entries. National snowfall map analysis, Christmas Day 2009. At 15:50, Aurora reported 33 mph gusting 48. Instead, 40 G 60 is substituted. Not since January 16, 2000, has a windstorm caused such widespread disruption in the western Pacific Northwest, and the more recent event appears to have been the bigger one.
I went to Washington Square yesterday. Some landed near the play structure, but there was enough open area to prevent a direct impact: Figure 14: Two cottonwoods snapped at Cascade Park, in Renton, among a number of other trees. Uudet käyttöehdot näet Voit tutustua tietosuojalausekkeeseen. The barometer at Eugene is 1008. The Seattle Seahawks football team figured in a large number of suggestions. Broken power lines were evident along parts of the highway. Many tree losses were hinge-falls, with very shallow root plates pulling from the ground.
The result of these factors was that many thousands of large, old trees easily uprooted and tipped over, frequently with tons of mud captured in their roots, and crashed into homes and power lines. A developing winter storm will bring the potential for freezing rain and ice accumulations across the central U. Blowing snow is not unusual one or twice each winter, but combine the blowing snow with 14. We do all the driving. If you were hoping to ring in 2019 on the slopes -- you may be out of luck. The crown crashed in the middle of the road and shattered.
Not only was fuel needed for travel, but for the thousands of generators running at homes and businesses. Still have 90% charge to go. These winds would concurrently produce a bona fide blizzard below, and box at right in Oklahoma, where more than a foot of snow was blown by sustained winds peaking near 50 mph and gusting over 60 mph at times! I wonder if the next phase of the storm is beginning--the arrival of the cold front. Note the shallow roots that have been pulled straight out of the ground, and how the soil pretty much has fallen away from the root mass. Sustained at 24 to 25 mph for four to five obs cycles say 10 seconds or so. The available evidence suggests that the same level of wind that afflicted SeaTac, gusts in the 60 to 70 mph range, struck the Renton Hill area.
