The National Weather Service in Baltimore MD/Washington has issued a coastal Flood Advisory... which is in effect until 6 am EST Friday. A coastal Flood Watch remains in effect from Friday morning through late Friday night.
Water levels at Annapolis are a foot above astronomical normals early Thursday morning. These departures will increase through the end of the week in response to a tight pressure gradient between low pressure off the Carolina coast and high pressure across the northeastern United States. As a result... strong northeast winds will push water into the Chesapeake Bay... and then toward the western shore.
During high tide today and tonight... water levels will be high enough so that minor flooding can be expected at times of high tide. Friday and Friday night... there is a better chance at minor flooding... with moderate flooding possible.
If moderate flooding becomes more certain... a coastal Flood Warning may be required.
Here are the times of the next high tides... 1:20 PM Thursday... 1:26 am and 2:19 PM Friday... and 2:14 am and 3:13 PM Saturday...
