Shownotes

A powerful winter storm is currently impacting the upper Midwest and Great Lakes, resulting in blizzard conditions that pose significant hazards to travel and safety. As we delve into this episode, we will explore the ongoing weather events, including whiteouts and scattered power outages affecting regions from Northern Michigan to parts of Minnesota. Additionally, we will discuss the gale force winds and rough seas prevalent along the Texas and Louisiana coasts, which are exacerbated by a strong post-frontal surge. Our analysis will also cover the recent earthquake detected near Susanville, California, and the resultant advisories in effect for wind and marine conditions along the Pacific Coast. We remain vigilant in monitoring these weather developments and their implications for the affected areas.

  1. A significant winter storm currently impacts the upper Midwest and Great Lakes regions.
  2. Travel conditions remain perilous due to ongoing winter storm warnings and advisories.
