No active NWS marine or coastal alerts cover this station right now (checked 2:02 AM AST).
National Weather Service, issued Thu 5:50 PM AST. Official forecast for AMZ741
We flag a predicted high at or above 2.5 ft MLLW (0.5 m above mean higher high water (MHHW), NOAA's national proxy for minor high-tide flooding, because NOAA lists no station threshold). We flag a predicted low at or below −1.0 ft MLLW. Mean higher high water is 0.8 ft.
No predicted tide in the next few days crosses either line.
Predictions are astronomical tides. Wind and pressure can move the real water level a foot or more. NOAA's sensor here read 0.6 ft at 1:54 AM.

No. When this page was built, no NWS marine or coastal alert covered this station.
Heights are in feet above mean lower low water (MLLW), the average of the lower of the two daily low tides. A negative number means the water is below that average.
