An updated hurricane forecast map is making it easier for people to identify areas threatened by storms, but new research reveals a concerning limitation. Even when people can recognize where hurricane watches are in effect, they may not feel more at risk or become more inclined to take precautions. Researchers at Florida State University examined whether changes to the National Hurricane Center (NHC) forecast graphics improve public understanding of hurricane threats.
The study involved faculty from the School of Communication within the College of Communication and Information and the Department of Geography. The researchers evaluated an experimental graphic that expands the traditional hurricane forecast cone to include tropical storm and hurricane watches and warnings for inland areas. The familiar cone has historically placed greater emphasis on coastal regions, even though dangerous storm conditions can extend far from the shoreline.
The findings revealed mixed results. Although the revised graphic helped people without specialized weather knowledge recognize inland areas under hurricane or tropical storm watches, it did not significantly influence how dangerous they believed the storms would be or whether they intended to take protective measures. Participants also showed no improvement in identifying areas covered by storm warnings.
The updated format was developed by the NHC in 2024, and the findings were published in the American Meteorological Society journal Weather, Climate, and Society. "The National Hurricane Center has made a number of thoughtful changes to improve how hurricane information is communicated," said Assistant Professor Elizabeth Ray, the study's lead author. "We had a simple question.
Do those changes actually help people understand what the graphic is telling them about the risk they face?" Why People Misunderstand Hurricane Forecast Maps To investigate how the public interprets hurricane forecasts, the research team surveyed residents of Florida and Georgia. Participants were shown either the conventional hurricane cone graphic or the newer experimental version that includes additional information about inland storm threats. People who saw the revised map were more successful at identifying locations under hurricane or tropical storm watches.
However, that improvement in recognizing watch areas did not lead to greater concern about the potential danger or stronger intentions to take safety precautions. The results also highlighted a persistent misunderstanding surrounding the familiar hurricane "cone of uncertainty." Many people incorrectly interpret the width of the cone as an indication of a storm's physical size, rather than understanding what the graphic is intended to communicate about the uncertainty in its projected track. "For years, research has shown that people often mistake a wider cone for a bigger storm," Ray said.
