Knots along the channel: above the line the flood, running in toward SE (142°); below it the ebb, running out toward NW (321°). Times are Alaska Daylight Time. Today: flood 0.2 kt 1:25 AM, slack 3:01 AM, ebb 0.2 kt 6:59 AM, slack 11:24 AM, flood 0.3 kt 2:02 PM, slack 4:17 PM, ebb 0.2 kt 8:07 PM, slack 11:24 PM.

None right now. The National Weather Service issues small craft advisories, gale and storm warnings, special marine warnings, dense fog advisories and coastal flood products for water like this.

The flood is the tidal current running in from the sea, the ebb the current running back out. Slack water is the short turn between them, when the current is weakest: the time to cross a strong channel, anchor, or dive. Slack in a channel is not the time of high or low tide; it can come hours after.

Speeds are knots along the channel's main axis, and directions are degrees true toward which the water flows, as NOAA prints its tables. A current against the wind stands the waves up steep and close together.

Predictions are astronomical: the moon and the sun, not the weather. Strong wind, river flow after heavy rain and storm surge all change the real current.
