Looks like we may be getting some wet weather, and this time of year that is pretty unusual. Good thing we don't have a substantial snow pack, these heavy warm rains can cause lots of flooding if we do:
Subject: Special Weather Statement: major fall storms with heavy rain and strong winds Thursday through the weekend PGPW - Special Weather Statement 1:30 pm Wednesday October 12, 2016 …Pineapple Express with Heavy Rain and Strong Winds Aimed at the Pacific Northwest Thursday Through the Weekend… A series of intense “atmospheric river” type storms off the Pacific will impact the Pacific Northwest late this week. A very strong, wet, subtropical jet off the Pacific will develop over the region beginning tonight through the weekend. The latest models are calling for an even wetter, windier, more intense storm than earlier forecast. If the more aggressive models came to fruition, this storm could rival some of the strongest storms of the past 50 years. Although the brunt of the rainfall and winds will be felt over western Oregon and western Washington, significant precipitation is also expected east of the Cascades. The heaviest rain of the period is expected tomorrow…with 1 ½ - 2 ½ inches along the I-5 corridor, 5 inches in the coastal mountains, and four inches in the Cascades. Since this is the first major rainfall of the season, no river flooding is forecast at this time…although flooding along small streams and ponding of water in low-lying areas is expected. Initially most of the precipitation will fall as rain in the mountains with snow levels Thursday up around 8,000-10,000 feet. Friday snow levels lower to 5,000-7,000 feet region wide as the first strong wave and cold front moves through the region. Strong, damaging winds are likely Thursday and Saturday over mainly the west side as two deep surface lows track through southwestern BC. Although there continues to be considerable uncertainty as to the timing and details, the main story lines remains that these are big, potentially record-breaking storms…and we are in store for a very wet and windy period. 5-Day Rainfall Totals: -Cascades and Coast Range: 8-16” -I-5 Corridor: 4-7” -Interior Mountains: 2-6” -East Side valleys: 1/2-2” Winds: -Coastal Beaches, Headlands, and Coast Ranges: gusts to 85 mph Thursday and to 95 mph Saturday -I-5 Corridor: gusts to 55 mph Thursday night and 60 mph Saturday night -exposed terrain of eastern Washington and eastern Oregon: gusts to 50 mph Friday and 55 mph Saturday Pacific Northwest Storm Parade, Including Remnant of Typhoon Songda, Could Bring Destructive Winds, Flooding, Huge Waves Looks like the big storm will make landfall north of Vancouver Island. What's so strange about this is that only an hour to hour and a half drive to the west in Willamina, Otis, or Lincoln City they get 122" of rain per year, while an hour to an hour and a half drive to the east out near The Dalles, Oregon you will find annual rainfall drops to 14". Rain forest to desert all in about 3 hours of driving. https://rainfall.weatherdb.com We really should change the name of this place to the Pacific Northdamp, because it just isn't that wet. We get about 36" of rain per year here in Portlandia. Hat tip: The King!
