Portland’s National Weather Service office warns that high seas and strong winds will make boating conditions hazardous starting Thursday night. A portion of west central Washington, including the Seattle area, is under a flood watch through Saturday afternoon. Tree damage and some power outages are possible, according to the weather service. back down to the Pacific Marine Environmental Laboratory in Seattle, Washington. Jeff Michalski, a meteorologist with the National Weather Service in Seattle, said to expect heavy rainfall across the region, including western Oregon, through Saturday evening, with the heaviest amounts over the Olympic and Cascade mountains. Watches: alert you about weather conditions that are favourable for a storm or severe weather, which could cause safety concerns. This huge pool of warm water disrupted the weather patterns and brought. Snow in the passes is expected as is potential river flooding, The Seattle Times reported. SEATTLE - An atmospheric river is bringing strong to damaging winds, heavy rain and below-normal temperatures for the Puget Sound region from Thursday evening through Saturday morning, the National Weather Service said. Hovering the time series with the cursor will show the minimum, maximum and mean vaules of the ensemble and the result of the main run.Watch Video: Wintry conditions forecast for West Coast, Pacific Northwest Because there are more potential forecast outcomes as you head farther out into the future, ensembles become especially useful after Day 4 or 5. Different ensemble systems have different numbers of ensemble members and the more ensemble members there are, the better the forecast will be as it will take into account a wider range of possibilities. If the ensembles disagree, it’s wise not to put too much confidence in one outcome or another. If all, or almost all, the ensemble members agree on a particular outcome, you can have high confidence that that outcome will occur. Ensembles are a great tool for gauging uncertainty in a forecast. In conjunction with Federal, State, and Local Emergency Managers and other public officials, NWR also broadcasts warning and post-event information for all types of hazards including natural (such as earthquakes or avalanches), environmental (such as chemical releases or oil spills), and public safety (such as AMBER alerts or 911 Telephone out. Each one of these ideas will create its own outcome, known as an ensemble member. Ensembles attempt to fix this problem by starting the model with a bunch of ideas of what the atmosphere could be doing right now. Any small error in the weather model initially due to this gap in observation is compounded exponentially out through time due to chaos. Because we can’t observe every tiny bit of air in our atmosphere, our picture of the weather currently is incomplete.
