Several beaches on Kauai have been closed due to strong currents.
Ocean Safety Bureau officials say Kalihiwai, Kee, Haena and Hanalei beaches were closed Monday.
Battalion Chief Albert Kaui says firefighters responded three times to swimmers being swept out of Kalihisai Bay and all were rescued successfully. He says everyone should exercise extreme caution given the conditions.
