Nor’easters, Pacific Hurricanes, and “Zombie Storms” with Dan DePodwin
From coastal flooding in the Northeast to tropical rainfall threats in the Pacific, this episode of the Disaster Podcast explores how changing weather patterns create challenges for communities and responders. Disaster meteorologist Dan DePodwin joins hosts Jamie Davis and Sam Bradley to discuss nor’easters, hurricane activity, El Niño, and storms that return after seemingly fading away. Dan begins by explaining what makes a storm a nor’easter and why these systems can cause problems well beyond snowfall. In the Northeast forecast discussed during the recording , the concerns include coastal wind gusts of 40–60 miles per hour, heavy rain, rough surf, and potential power outages. Persistent onshore winds have already set the stage for coastal flooding, with the Jersey Shore, Long Island, and southeastern New England among the areas of concern. The conversation then shifts to the Pacific, where tropical systems threaten both island communities and the mainland. Dan describes how tropical moisture interacting with Hawaii’s mountainous terrain can produce extreme rainfall, flash flooding, and landslides. Another concern is moisture moving inland from the eastern Pacific, potentially bringing flooding to parts of the Southwest and central United States. A storm’s effects can extend far beyond its coastal track. National Hurricane Center Website El Niño provides a broader backdrop for the discussion. Dan explains how warmer equatorial Pacific waters and changes in atmospheric conditions can influence tropical activity and weather patterns around the world. He also distinguishes those large-scale influences from the ingredients that produce an individual storm: understanding El Niño helps explain the seasonal picture, but it does not mean every weather event has a single cause. Sam brings a personal perspective to the discussion, recalling a tornado warning while driving through Missouri. She describes taking shelter in a convenience store as warning sirens sounded and later learning that a tornado had struck in the general area. Her experience leads into a conversation about seasonal tornado risks and the importance of paying attention to changing conditions while traveling. The group also explores so-called “zombie storms”—tropical systems that weaken or lose their tropical characteristics before reorganizing. Hurricane Ivan comes up as the hosts and Dan discuss how a storm’s story can continue long after its initial impact. Throughout the episode, Dan connects the weather science with the practical concerns facing responders: coastal flooding, inland rainfall, power disruptions, and rapidly changing forecasts. Listen for a conversation about understanding the hazards behind the storm names and keeping the full geographic reach of a weather event in view.
