Active NWS alerts

Unusual tides here

We flag a predicted high at or above 22.2 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 20.5 ft.

No predicted tide in the next few days crosses either line.

Official sources
