SITUATION OVERVIEW
------------------
Isaias will affect the coastal Carolinas tonight. Heavy rain and high
winds will be the main impacts. Winds will be of tropical storm
intensity inland while hurricane force winds are possible in coastal
counties. Tornadic rainbands are expected to start rotating onshore
during the overnight hours. Strong onshore winds are expected to bring
a storm surge to the beaches that will cause areas of beach erosion as
well as inundation of areas beyond the dunes especially south of Cape
Fear. Heavy rainfall is expected to cause areas of flash flooding.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against dangerous wind having possible significant impacts
across northeast South Carolina and southeast North Carolina east of
I-95. 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, protect against hazardous wind having possible limited impacts
across areas west of I-95.
* TORNADOES:
Protect against a dangerous tornado event having possible significant
impacts across northeast South Carolina and southeast North Carolina east of
I-95. Potential impacts include:
- The occurrence of scattered tornadoes can hinder preparedness
actions during tropical events.
- Tornadoes can rip roofs from homes, destroy mobile homes, cause
trees to become snapped or uprooted, flip cars and boats.
Dangerous projectiles can add to the damage.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
Protect against a tornado event having possible limited impacts
across areas west of I-95.
* FLOODING RAIN:
Protect against 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.
* SURGE:
Protect against life-threatening surge having possible significant
impacts across area beaches south of Cape Fear. 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, protect against locally hazardous surge having possible limited
impacts across areas north of Cape Fear.
Elsewhere across southeast North Carolina and northeast South
Carolina, little to no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.
If you are relocating to safe shelter, leave as early as possible. If
heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or own a
pet. Take essential items with you from your Emergency Supplies Kit.
Check the latest weather forecast before departing.
Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.
In emergencies it is best to remain calm. Stay informed and focused
on the situation at hand. Exercise patience with those you encounter.
Be a Good Samaritan and helpful to others.
If relocating to a nearby shelter or to the home of a family member
or friend, drive with extra caution, especially on secondary roads.
Remember, many bridges and causeways will be closed once higher winds
arrive. Also, if you encounter water covering the road, seek an
alternate route. Always obey official road signs for closures and
detours.
If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.
Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
