Coastal Flood Warning As of 4:09 am EST on March 13, 2010

... Coastal Flood Warning in effect until 10 PM EST this evening...

The National Weather Service in Baltimore MD/Washington has
issued a coastal Flood Warning... which is in effect until 10 PM
EST this evening. The coastal Flood Advisory is no longer in
effect. The coastal Flood Watch is no longer in effect.

Water levels were running 1 to 1.5 feet above normal on the upper
Chesapeake Bay and upper tidal Potomac River early this
morning... and were running around 2 feet above normal on the
middle Chesapeake Bay and lower tidal Potomac River. These
positive departures will continue to result in minor tidal
flooding during the remaining high tides this morning.

With a persistent and gusty easterly wind... water levels are
expected to further increase to 2 to 3 feet above astronomical
predictions later today. This combined with the new moon phase of
the lunar cycle is expected to result in moderate tidal flooding
during high tide times this afternoon and evening.

Minor to moderate tidal flooding will continue to be possible
into Sunday as water levels will be slow to recede. In
addition... runoff from heavy rainfall will enhance the flood
threat on the upper tidal Potomac River.

Here are the times of the next high tides
for a few locations from north to south...
on the Chesapeake Bay...
Havre de Grace... 8:00 am and 8:51 PM...
Bowley Bar... 5:38 am and 6:30 PM...
Fort McHenry Baltimore... 4:47 am and 5:38 PM...
Annapolis U.S. Naval Academy... 4:08 PM...
Solomons Island... 1:00 PM...

Alexandria... 6:46 am and 7:07 PM...
Indian Head... 6:14 am and 6:35 PM...
Goose Bay... 2:41 PM...

A coastal Flood Warning means that flooding is occurring or

for rising water... and take appropriate action to protect life
and property.
