  * WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways (5.6 to 7.2 feet Mean Lower Low Water). * WHERE...Washington, Southern Bristol MA, Southern Plymouth MA, Southeast Providence RI, Eastern Kent RI, Bristol RI, and Newport RI Counties. * WHEN...From 5 PM this afternoon to 8 PM EDT Sunday. * IMPACTS...Splashover and Minor coastal flooding is expected in the lowest lying areas along the south coast of Rhode Island and Massachusetts over multiple high tide cycles late today through this weekend. A few immediate coastal roads may briefly flood due to wave action. In addition...minor beach erosion is also possible.

  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.
