Sea Condition Caution (SC-C): Wind speeds of 18 MPH (16 KT) or greater, including gusts, have been observed for at least 3 hours. Locally assessed conditions warrant that individuals participating in water activities have extensive experience both in the planned activity and at the location.

Sea Condition Danger (SC-D): Wind speeds of 35 MPH (30 KT) or greater, including gusts, have been observed and are to persist for at least 3 hours or during TCCOR 2. Locally assessed conditions are dangerous and warrant restricting access to the water and removal of individuals from the water. Note – Military facilities will cease rental of water recreation equipment in SC-D.

Important Note: Conditions and criteria are based on a generalized evaluation and may not be consistent with the weather and sea state throughout the entire coastline of Okinawa. Therefore, personnel must make an individual assessment of the hazards for their intended activity during SC-AC and SC-C.
