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

Tropical Storm Isaias will slowly track northward along the east coast
of Florida on Sunday before approaching the Carolinas as a Tropical
Storm late Monday. The most significant impacts are expected to occur
Monday night into Tuesday morning. These impacts include the potential
for tornadoes and tropical storm force winds, mainly east of I-95,
along with heavy rainfall. A combination of onshore winds and elevated
tides could lead to minor coastal inundation, especially in Coastal
Brunswick County and points southward. Significant marine impacts are
expected due to tropical storm force winds, high seas, dangerous rip
currents, and high surf.

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

* WIND:
Prepare for dangerous wind having possible significant impacts across
southeast North Carolina and northeast South Carolina. Potential impacts
in this area include:
    - Some damage to roofing and siding, along with damage to porches
      and awnings. A few buildings experiencing window, door, and
      garage door failures. Damage to vulnerable structures such as
      carports, sheds and mobile homes is possible.
    - Large limbs will be down with several trees snapped or
      uprooted. Several fences and roadway signs may become blown
      over. Some roads may become impassable due to large debris
      blocking the roadway, especially within urban or heavily wooded
      locations. Some bridges, causeways, and elevated roads may be
      impacted by high winds making driving on them hazardous.
    - Scattered power and communications outages are possible, but
      more prevalent in areas with above ground lines.
    - Small craft that are not properly moored may break loose.

Also, prepare for hazardous wind having possible limited impacts
across southeast North Carolina and northeast South Carolina.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across southeast North Carolina and northeast South Carolina.
Potential impacts in this area include:
    - Areas of storm surge inundation enhanced by breaking waves are
      possible along the barrier islands. Damage to several buildings
      is possible, mainly near the coast.
    - Sections of near-shore roads may become weakened or washed out,
      especially in vulnerable low-lying areas.
    - Delivery of drinking water and sewer services may be
      interrupted.
    - Major beach erosion is possible with heavy surf and elevated
      water levels impacting or breaching the dunes.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft will break away from moorings, especially
      in unprotected anchorages.
    - Navigation may be difficult near inlets and waterways, as
      navigational aids may be off station or missing.

Also, prepare for locally hazardous surge having possible limited
impacts across southeast North Carolina and northeast South Carolina.

Elsewhere across southeast North Carolina and northeast South
Carolina, little to no impact is anticipated.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across southeast North Carolina and northeast South Carolina.
Potential impacts include:
    - Moderate flooding from rainfall may prompt some evacuations and
      rescues.
    - Rivers and streams may rise and overspill their banks in a few
      places, especially in the typical prone locations. Small creeks
      and ditches may overflow.
    - Flood waters may enter some structures. Underpasses, low-lying
      spots along roadways, and poor drainage areas may become
      submerged by rising water. Some secondary streets and parking
      lots may flood as storm drains and retention ponds overflow.
    - Driving conditions will become hazardous, and some road
      closures can be expected.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
southeast North Carolina and northeast South Carolina. Potential
impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Tornadoes can cause damage to trees, vehicles, boats, and
      buildings. Unsecured mobile homes and poorly constructed
      structures are particularly vulnerable.

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

* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, plan to move to safe shelter.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
