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

Tropical Storm Irma is over North Central Florida and will track into
Southwest Georgia this afternoon and evening. While the Tornado threat
and Flood Threat is decreasing, strong winds of tropical storm force
with gusts to hurricane force will continue into the afternoon hours.
The strong winds will continue the storm surge threat along the
Atlantic Coast and with the winds switching to the South there will be
an enhanced threat of Storm Surge in the St. Johns River specifically
in downtown Jacksonville where record flooding will continue along the
St. Johns River Basin. Conditions will improve this evening and during
the overnight hours tonight as winds decrease and flood waters slowly
subside. Major to Record River flooding will continue across Northeast
Florida for several days to come.

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

* WIND:
Impacts from the main wind event are still continuing across Northeast
Florida and Southeast Georgia. Remain well sheltered from dangerous
wind having additional significant impacts. If realized, these impacts
include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

* SURGE:
Potential impacts from the main surge event are now unfolding across
the St. Johns River Basin including downtown Jacksonville. Remain well
away from life-threatening surge having additional significant
impacts. If realized, these impacts include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore escape routes and secondary roads become
      weakened or washed out, especially in usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Significant impacts from the surge event will continue along the
Atlantic Coastal areas. Remain well away from locally hazardous surge
having possible additional limited impacts.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
inland Southeast Georgia with an additional 2 to 4 inches of rainfall
possible this afternoon. Remain well guarded against life-threatening
flood waters having additional extensive impacts. If realized, these
impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may
      become dangerous rivers. Flood control systems and barriers may
      become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

Significant impacts from the flooding rain are still unfolding across
Northeast Florida and flooded areas will be very slow to recede.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Do not return to evacuated areas until hazardous winds diminish and
flood waters abate.

Do not return to evacuated areas until it is safe. Listen for the all-
clear signal from local authorities.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay inside
and away from windows. Listen for updates and be ready in case you
lose electrical power. Locate your battery powered radio and flashlight
from your Emergency Supplies Kit. Keep these items close.

During the peak of the storm, keep your shoes on and rain gear handy.
Boots and tennis shoes offer the best foot protection if you become
unexpectedly exposed to the elements.

Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.

Do not venture outside while in the eye of a hurricane. Within the
eye, weather conditions may temporarily improve which can be
misleading. Once the eye passes, the wind will change direction and
return to dangerous speeds. Heavy rain will also return. Be smart and
remain safely hidden from the storm.

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Be ready to move to the identified safe room if your home or shelter
begins to fail. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.

When major hurricanes make landfall, extreme winds bring a tremendous
threat to life and cause devastating to catastrophic damage. During
landfall, listen for extreme wind warnings which indicate the exact
timing and location of these incredible life-threatening winds. If
issued for you area, move to the safest place within your home or
shelter. Take the same life-saving actions as if it were a violent
tornado.
