Weather renders all people vulnerable, but due to various factors some are more naturally vulnerable than others. What of those vulnerable populations and individuals who cannot take, or are limited in taking, protective actions? This paper contributes to the mission of the Weather Ready Nation initiative (WRN), established by the U.S. National Weather Service, by shining light on weather communication considerations for those on the autism spectrum and those with color vision differences. It also discusses ongoing efforts centered around the Deaf and hard-of-hearing and those who are blind or who have limited vision, and discusses problems existing in weather communication for vulnerable populations at-large. The first section defines vulnerability and clarifies associated concepts while the second section, on ways to improve weather communication practices for autistic people and those who are blind, vision-limited, Deaf, hard-of-hearing, and those with color vision-processing differences, focuses on the importance of recognizing lived, vulnerable population experience in weather messaging efforts and the use of language in communicating with the aforementioned populations.
