SITUATION OVERVIEW
------------------

Tropical Storm Isaias, located off the Florida East coast, will continue
on a north-northwest track this evening. Isaias is expected to begin a
more northward turn late tonight, which will bring the tropical storm
near the northeast Florida Atlantic coast by early Monday morning. Due
to the close approach of Isaias to the northeast Florida coast, a Tropical
Storm Warning is in effect for all of the coastal areas of northeast FL
and southeast GA. Tropical storm conditions may reach the coast as early
as late this evening and then continue through Monday, diminishing Monday
evening.

Isaias will also bring a threat of minor storm surge flooding with large
waves to the coast. Surge values of 1 to 3 feet are possible along the
northeast Florida and southeast Georgia coasts. Significant to severe beach
erosion will be likely for some of the area beaches. Coastal flooding from
storm surge may begin this evening and continue through late Monday evening.

Life-threatening rip currents and building rough seas are expected through
Monday and swimming is strongly discouraged at area beaches. Rain bands
with gusts near tropical storm force will move into the Northeast Florida
coastal counties this evening, and this activity will increase and intensify
late tonight into Monday morning. Additional Rainfall amounts of 1 to 2 inches
are expected, with localized heavier amounts possible. Urban and poor drainage
areas may experience localized flooding.

Over the coastal waters, dangerous marine conditions will continue
through Monday evening.

POTENTIAL IMPACTS
-----------------

* WIND:
Protect against hazardous wind having possible limited impacts across
coastal northeast Florida and coastal southeast Georgia. Potential impacts
in this area include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

Elsewhere across Northeast Florida and Southeast Georgia, little to
no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across coastal northeast Florida and coastal southeast Georgia.
Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

Elsewhere across Northeast Florida and Southeast Georgia, little to
no impact is anticipated.

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across coastal northeast Florida and coastal southeast
Georgia. Potential impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, and ditches may become swollen
      and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across Northeast Florida and Southeast Georgia, little to
no impact is anticipated.

PRECAUTIONARY/PREPAREDNESS ACTIONS
