  * WHAT...Northeast winds 15 to 25 kt with gusts up to 35 kt and seas 3 to 6 ft. * WHERE...Penobscot Bay and Casco Bay. * WHEN...Until 8 AM EDT Monday. * IMPACTS...Conditions will be hazardous to small craft.

  Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions.

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.
