  * WHAT...Up to one half foot of inundation above ground level in low-lying areas near shorelines and tidal waterways. * WHERE...Coastal Horry and Coastal Georgetown Counties. * WHEN...Until 10 PM EDT this evening. * IMPACTS...Vulnerable causeways to and from local beaches may experience minor coastal flooding. Low-lying roads and locations along the Intracoastal Waterway and adjacent tidal creeks may observe minor coastal flooding. Check with local officials for the latest information regarding coastal flood impacts and closures. * ADDITIONAL DETAILS...Affected areas listed are based on average tide conditions. Additional locations may experience flooding during periods of heavy rainfall, high winds, or other factors.

  If travel is required, allow extra time as some roads may be closed. 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. 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.
