This Hazardous Weather Outlook is for the Florida Keys and
adjacent coastal waters.

.DAY ONE...TODAY AND TONIGHT

A coastal flood advisory is in effect for all of the Florida Keys.
Coastal flooding will affect low lying areas of the Lower and
Middle Keys around the time of higher high tide in the Lower
Florida Keys, and during the extended high tide in the Middle
Keys. The highest water will occur after midnight until sunrise.
For the Bayside communities of the Upper Keys, water levels will
tend to stay high, with little relief at low tide.

In addition, a Small Craft Advisory will be required for all Keys
coastal waters tonight.

Isolated thunderstorms are expected this afternoon and evening,
with some wind gusts in excess of 40 mph possible. The primary
thunderstorm threats will be cloud to surface lightning strikes
and strong gusty winds.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Minor coastal flooding will be possible across low-lying portions
of the Florida Keys as predicted high tides remain above normal
this week. The coastal flooding will be greatest around the times
of higher high tides in the Middle and Lower Keys, but water
levels will remain high even during low tide within the Bayside
communities of the Upper Keys.

A Small Craft Advisory may be required for portions of our marine
district Saturday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.

Coastal Flood Advisory

Coastal Hazard Message

930 AM EST Fri Nov 15 2019

FLZ076-077-161000-
/O.EXT.KKEY.CF.Y.0008.000000T0000Z-191116T2200Z/
Monroe Upper Keys-Monroe Middle Keys-
930 AM EST Fri Nov 15 2019

...COASTAL FLOOD ADVISORY IN EFFECT...

* COASTAL FLOODING...Saltwater flooding is expected over the
  Middle Keys, with total water levels reaching about 2 feet
  above mean sea level. This is about 1.25 feet above the normal
  predicted tide. Saltwater flooding is also expected across the
  Upper Keys, especially the Bayside communities of Key Largo.
  Total water levels about 2 feet above mean sea level, or 1.25
  feet above the normal predicted tide, are possible.

* TIMING...Across the Middle Keys, impacts from saltwater flooding
  will be greatest during the extended high tide. The next
  extended high tide will occur from late this evening through the
  overnight hours. Across the Upper Keys, impacts from saltwater
  flooding will tend to persist, despite the tidal cycle, with
  little or no relief at low tide.

* IMPACTS...Saltwater flooding of low elevation streets and lots
  is expected. Some 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 are almost certain to contain a mix of
  saltwater.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory indicates that above normal tides will
cause flooding of low areas along the shore.
