  * WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE...Coastal Brunswick County. * WHEN...From 6 AM to 10 AM EDT this morning. * IMPACTS...Low-lying roads and locations along the Intracoastal Waterway and adjacent tidal creeks may observe minor coastal flooding. Check with local officials for any road closures or impacts.

  Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.

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.
