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

Tropical Storm Idalia was located over southeastern Georgia, and
is moving toward the northeast. This general motion is expected to continue
through tonight, shifting to the east...northeast on Thursday.  On the forecast
track, the center of Idalia will move near or along the coasts of Georgia
and South Carolina through tonight, and then just offshore of the coast of North
Carolina on Thursday. Idalia will make it closest approach Thursday
afternoon as a tropical storm and as it tracks east, south of Cape
Lookout.

Tropical storm force wind gusts are expected to develop by Thursday
morning for coastal and inland portions of Currituck County as well as the
Currituck Sound, and adjacent coastal waters. A Tropical Storm Warning remains
in effect for these areas. Additionally, the pressure gradient between Idalia's
circulation and high pressure to the north will result in strong winds
along the coast, even outside of the Tropical Storm Warning area.
Strong winds could lead to downed trees and scattered power outages.
Strong onshore winds could also lead to areas of minor to locally
moderate coastal flooding.

Heavy rain is expected tonight a cold front stalls near the Virginia, North
Carolina border, and will continue through Thursday evening. There will likely be
a sharp rainfall gradient across the local area as high pressure builds into
the northern mid Atlantic region on Thursday. Rainfall totals will range from
3 to 5 inches across northeast North Carolina, where a Flood Watch remains in
effect. One to two inches will be possible across far southeast Virginia.

Dangerous marine conditions are expected to develop by early Thursday
with strong winds lasting into early Friday. Seas build to 7 to
12 feet on Thursday and remain elevated into Saturday.

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

* WIND:
Protect against hazardous wind having possible limited impacts across CURRITUCK
COUNTY NC, and coastal areas of SOUTHEAST VIRGINIA.
. 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, especially if soils are saturated. Some roadway signs
      will sustain damage.
    - A few roads will be impassable from debris. Hazardous driving
      conditions on bridges and other elevated roadways.
    - Scattered power and communications outages.

Elsewhere across CENTRAL AND EASTERN VIRGINIA...AND THE LOWER MARYLAND
EASTERN SHORE, little to no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across SOUTHEAST VIRGINIA and NORTHEAST NORTH CAROLINA. Potential impacts in
this area include:
    - Widespread storm surge flooding of vulnerable areas will result
      in an elevated threat of property damage to homes and
      businesses near the waterfront and shoreline.
    - Sections of low-lying vulnerable roads, parking lots and
      property will likely become flooded. Driving conditions could
      become dangerous in places where flooding covers the road.
    - Moderate to severe beach erosion is likely, including heavy
      surf possibly breaching dunes, especially in vulnerable
      locations. Strong and dangerous rip currents are likely.
    - Minor to moderate damage to marinas, docks, boardwalks, and
      piers is likely. A few small craft broken away from moorings.

Elsewhere across CENTRAL AND EASTERN VIRGINIA...AND THE LOWER MARYLAND
EASTERN SHORE, little to no impact is anticipated.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across NORTHEAST NORTH CAROLINA. Potential
impacts include:
    - Flooding from heavy rainfall may prompt evacuations and rescues
    - Rivers and tributaries may quickly become swollen, with swift
      currents, and overspill their banks. Small streams, creeks, and
      ditches overflow.
    - Flood waters can enter some structures and/or weaken
      foundations. Some areas may experience areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures are expected.

Protect against locally hazardous rainfall flooding having possible
limited impacts across FAR SOUTHEAST VIRGINIA.

Elsewhere across CENTRAL AND EASTERN VIRGINIA...AND THE LOWER MARYLAND
EASTERN SHORE, little to no impact is anticipated.

* TORNADOES:
Little to no impacts are anticipated at this time
across CENTRAL AND EASTERN VIRGINIA...NORTHEAST NORTH CAROLINA...AND
THE LOWER MARYLAND EASTERN SHORE.

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
