...HIGH SURF ADVISORY WILL EXPIRE AT 5 AM CHST EARLY THIS
MORNING...
...COASTAL FLOOD STATEMENT WILL EXPIRE AT 5 AM CHST EARLY THIS
MORNING...

Altimetry and model data support that the mixture of the northeast and
north swells has diminished enough to allow surf along north facing
reefs to drop below 9 feet. Also, with the magnitude/peak heights of
high tides continuing to decrease, the risk of minor coastal
flooding has also ended. The High Surf Advisory and Coastal Flood
Statement will be allowed to expire at 5 AM PM ChST this morning.
