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

.DAY ONE...TODAY AND TONIGHT

Isolated thunderstorms are anticipated along the Florida Keys and
the surrounding coastal waters through tonight. The primary
thunderstorm hazards will be cloud to surface lightning strikes
and strong gusty winds with the stronger and rapidly moving
cells.

The observed water levels are currently within Coastal Flood
Statement thresholds for the Lower and Middle Florida Keys. Hence,
a Coastal Flood Statement will be extended for these islands due
to minor saltwater flooding of low-lying lots and roads through
tonight.

However, water levels are expected to rise higher on Florida Bay
adjacent to the Upper Keys. Subsequently, a Coastal Flood
Advisory is in effect for this area. In addition to salt water
flooding of low-lying lots, take the necessary actions to protect
flood-prone property.

And finally, A Small Craft Advisory is in effect for our entire
marine district through tonight.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

Isolated to scattered thunderstorms are anticipated  along the
Florida Keys and the surrounding coastal waters through at least
Wednesday night, before possibly decreasing in coverage later
Thursday into early next weekend.

The primary thunderstorm hazards will be cloud to surface
lightning strikes and strong gusty winds which may require Special
Marine Warnings issued by your National Weather Service right here
in Key West. Please stay tuned.

Meanwhile, saltwater flooding of low-lying lots and roads will
continue to require Coastal Flood Statements and or Coastal Flood
Advisories for all the Florida Keys today, and persisting through
at least the middle of this week.

And finally, a Small Craft Advisory will likely be required
Monday through at least Thursday.

Beyond Thursday, only isolated thunderstorms are possible along
the Florida Keys and the surrounding coastal waters.

The primary thunderstorm hazard will be cloud to surface lightning
strikes.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.

441 PM EDT Mon Oct 19 2020

...COASTAL FLOOD ADVISORY IN EFFECT...

* WHAT...Saltwater flooding.

* WHERE...Middle and Lower Florida Keys.

* WHEN...Especially at the times of high tide, which will be
  around and just after midnight.

* 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 around the times of high tide are almost certain to
  contain a mix of saltwater.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of unknown
depth. Take the necessary actions to protect flood-prone
property. Boaters should lower biminis and antennae, and approach
fixed bridges at the safest navigable speed, noting that clearance
beneath bridges will be reduced.
