  * WHAT...For the Gale Warning, northeast winds 25 to 30 kt with gusts up to 40 kt and seas 8 to 13 feet. For the Storm Warning, northeast winds 30 to 40 kt with gusts up to 55 kt and seas 11 to 16 feet expected. * WHERE...Sandy Hook NJ to Fire Island Inlet NY out 20 NM. * WHEN...For the Gale Warning, until 6 PM EDT this evening. For the Storm Warning, from 6 PM this evening to 6 AM EDT Sunday. * IMPACTS...Storm force winds and hazardous seas will capsize or damage vessels and reduce visibility.

  Mariners should remain in port, alter course, and/or secure the vessel for severe 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. This is a subordinate station: NOAA predicts it from a nearby harmonic station by fixed corrections to the times and speeds of its slack waters and maxima, so the curve between them is less exact.
