Tropical depression Flossie is expected to exit Hawaii Tuesday, weaker than when it arrived.
Flossie brought widespread thunder, lightning, and heavy rain that left thousands of residents without power and some without water.
It also shut down schools and government buildings and prompted the governor to declare an emergency.
"Mother nature throws curve balls at us to make us more busy," said Warning Coordination Meteorologist Michael Cantin, with the National Weather Service in Honolulu.
Flossie is the biggest storm to hit Hawaii in 20 years.
