 Paralleling the coastline , the storm produced a light storm surge that peaked at 2 @.@ 6 feet ( 0 @.@ 8 m ) above normal on Sanibel Island . In some locations , the surge rose rapidly , and , despite the unusual geography of the area , the levels varied only by as much as 9 @.@ 8 inches ( 250 mm ) than the predicted levels from the SLOSH model . The surge and waves caused minor beach erosion . Moderate to heavy rainfall fell across western Florida , peaking at 6 @.@ 14 inches ( 156 mm ) near Bradenton ; the rainfall was beneficial after a very dry summer , though , because it fell quickly , even this amount of precipitation failed to relieve water restrictions across the area . The storm resulted in some flooding in its path , including some several homes in Manatee County , roadways , and two U.S. highways . Statewide damage totalled $ 3 million ( 1990 USD , $ 5 @.@ 43 million 2016 USD ) , of which $ 1 million ( 1990 USD , $ 1 @.@ 81 million 2016 USD ) occurred in Manatee County .
