  * WHAT...Around 1 to 1 1/2 ft of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. The highest water levels are likely with the Saturday morning and possibly Sunday morning high tides. * WHERE...Southern Middlesex and Southern New London Counties. * WHEN...During the times of high tide until 6 PM EDT Sunday. * IMPACTS...Minor flooding is expected in the most vulnerable locations near the waterfront and shoreline. Expect around 1 to 1 1/2 feet of inundation above ground level in low lying, vulnerable areas. Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding. * ADDITIONAL DETAILS...Another round of minor coastal flooding is possible for the Sunday morning high tide cycle.

  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.
