Rainwater is a vital resource and dynamic driver of terrestrial ecosystems. Yet, processes controlling precipitation inputs and interactions during storms are often poorly seen, and poorly sensed when direct observations are substituted with technological ones. We discuss how human observations complement technological ones, and the benefits of scientists spending more time in the storm. Human observation can reveal ephemeral storm-related phenomena such as biogeochemical ‘hot moments’, organismal responses, and sedimentary processes which can then be explored in greater resolution using sensors and virtual experimentation. Storm-related phenomena trigger lasting, oversized impacts on hydrologic and biogeochemical processes, organismal traits/functions, and ecosystem services. We provide examples of phenomena in forests, across disciplines and scales, to inspire mindful, holistic observation of ecosystems during storms. We conclude that technological observations alone are insufficient to trace the process complexity and unpredictability of fleeting biogeochemical or ecological events without the “shower thoughts” produced by scientists’ human sensory and cognitive systems during storms.
