The National Weather Service in Baltimore MD/Washington has
issued a coastal flood advisory, which is in effect from midnight
tonight to 8 am EDT Friday.

* Locations... shoreline in southeast Harford County.

* Tidal departure... 1.5 to 2 feet above normal due largely to
excess fresh water from the Susquehanna River.

Grace is at 3:30 am.

* Impacts... water is expected to go over The Bulkhead at the
Havre de Grace Yacht Basin. Minor shoreline inundation up to one
foot above ground is possible elsewhere.

Precautionary/preparedness actions...

A coastal flood advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.
