NOTE: During times when the area is under a Tropical Storm/Hurricane Watch or Warning, the storm tide or total water level forecast will reflect a plausible worst case scenario (versus the usual most likely scenario).

NOTE: Coastal flood impacts are dependent upon waves as well as tide level. High waves can result in flooding even if the tide level is below flood stage.

Reliability of the Forecast: Forecast data shown here are guidance values only. Please refer to your local NWS office.

NOTE: Forecasts for the Narragansett Bay at Newport Harbor are issued routinely year-round.

9 Widespread flooding is likely across coastal sections of Newport and Middletown. The combination of high tides and wave action may force evacuations of some lower lying areas. Alternate routes may be required as coastal roads become impassable.
7 Minor flooding can be expected across low lying areas of Newport and Middletown. Several immediate coastal roads may be impassable for a few hours around time of high tide. Minor beach erosion on the south side of Newport is possible.
6.6 Minor coastal flooding is expected in the lowest lying areas of Aquidneck Island. A few immediate coastal roads may briefly flood due to wave action.
