Coastal Flood Advisory now a Warning

Low pressure and persistent winds from the east and southeast are pushing/drawing water up the bay, pumping today's high tides Thursday two to three feet above normal.

UPDATE, 12:45 p.m.: The National Weather Service has issued Flood Warnings for urban areas and small streams in Baltimore City and County, Anne Arundel Howard and Harford counties until 4:30 p.m.:  

"AT 1234 PM EST RADAR ESTIMATES AND SURFACE REPORTS INDICATE OVER
  AN INCH OF RAIN HAS FALLEN IN THE LAST SIX HOURS IN THE BALTIMORE
  METRO REGION.

" NUMEROUS AREA CREEKS AND STREAMS HAVE RISEN OWING TO THE RAINFALL
  AND WILL CONTINUE TO RISE AS MORE RAIN CONTINUES THIS AFTERNOON.

" A FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR HAS BEEN REPORTED.
STREAM RISES WILL BE SLOW AND FLASH FLOODING IS NOT EXPECTED.
HOWEVER...ALL INTERESTED PARTIES SHOULD TAKE NECESSARY PRECAUTIONS
IMMEDIATELY."

EARLIER: The weather service has also replaced Coast Flood Advisories with Coastal Flood Warnings on the Western Shore. Here's how the tide gauge at Baltimore is looking just after 11 a.m.
