Active Pattern Next Two Weeks, Major Storm Possible on Friday
According to a 2005 Gallup poll, Americans think November is the 8th best month of the year. November has a few things going for it; the Macy’s Thanksgiving Day Parade, increasingly competitive football games, not-shaving – but it seems most Americans believe these attributes are overshadowed by how dark, cold, and depressing the month is […]
Historic Storm For Southern Oregon/Northern California on Tuesday
By now, many of us have heard of the term “bomb cyclone.” Just like “polar vortex,” “bomb cyclone”/”bombogenesis”/”meteorological bomb” (and many other bomb-related derivatives) has actually been in the meteorological literature for decades, first entering the vernacular in the Bergen School in the 40s and 50s to describe the explosively-developing cyclones over the North Atlantic.

Storm Season Begins Wednesday
We will enter a much stormier pattern Wednesday that will persist through the weekend and possibly beyond, with moderate/strong systems affecting the area every 24-36 hours.

In this blog, I’ll cover the basic characteristics of an atmospheric river, how these atmospheric rivers form, and a brief summary of how they relate to the Earth’s heat budget. Throughout the blog, I’ll use […]

Carol Snider – Urban Flooding in Seattle – December 3, 2007 Approximately four years ago, one of the strongest storms to ever hit our area, the “Great Coastal Gale,” brought hurricane-force winds to the coast and major flooding throughout the area.

Floods in the Pacific Northwest
Wednesday, October 6, 2010 Many people would be surprised to find out that the Pacific Northwest gets some of the biggest floods in the world. The reason why it is not common knowledge is because the places that flood are usually sparsely populated (like Snoqualmie or Concrete) or have no people at all (like many […]
