It is true, Hurricane Harvey’s rating on the Saffir-Simpson intensity scale has fallen from Category 4 to Category 1 since making landfall near Rockport, Tex., Friday night.
But the Saffir-Simpson scale is only a measure of storm’s wind speed, and this storm’s most severe impact is expected to be disastrous rainfall. And the worst rain from Harvey is yet to come.
Gina Eosco, a social scientist who specializes in how people perceive weather messages, stressed that people who talk about this storm do not say it has been downgraded when the threat of catastrophic flooding looms.
“Do not say the ‘storm downgraded’,” she tweeted. “Inaccurate. Only wind. Emphasize #harvey flooding rain risk **for days**”
