Coastal Flood Advisory

Coastal Hazard Message
National Weather Service Key West FL
1008 PM EDT Mon Oct 14 2019

FLZ076-077-151000-
/O.CON.KKEY.CF.Y.0006.000000T0000Z-191015T2100Z/
Monroe Upper Keys-Monroe Middle Keys-
1008 PM EDT Mon Oct 14 2019

...COASTAL FLOOD ADVISORY REMAINS IN EFFECT...

* COASTAL FLOODING...Saltwater flooding will continue to affect
  the Upper and Middle Keys, with total water levels reaching
  nearly two feet above mean sea level, or between 1.0 and 1.3
  feet above the predicted tide levels.

* TIMING...For the Middle Keys, the impacts from saltwater
  flooding will be greatest at the times of high tide, which
  will occur between midnight and 4 am, and also late Tuesday
  afternoon. Across the Upper Keys, water levels will stay high,
  with little to no relief at low tide.

* IMPACTS...Saltwater flooding of low elevation streets and lots
  is expected. Low-lying storm drains will overflow and some
  seawalls and docks will be overtopped. Boaters can expect less
  clearance under fixed bridges. Motorists should remember that
  persistent puddles around the times of high tide are almost
  certain to contain saltwater.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory indicates that above normal tides will
generate moderate flooding of low lying areas.
