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

Tropical Storm Idalia is situated just offshore of Wilmington, North
Carolina as of late this morning. The storm will continue its
eastward trek further offshore through the rest of today.

Tropical storm force winds continue this morning across the land
areas of Currituck County, in addition to the Currituck Sound and the
offshore 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 isolated instances of
downed trees and power outages. Strong onshore winds are also expected
to lead to areas of minor to moderate coastal flooding.

The heavy rainfall threat is quickly diminishing. However, up to an
inch of additional rainfall is possible across northeast North
Carolina through this afternoon. This is on top of a general 1 to 3
inches that fell earlier this morning. A flood watch remains in
effect for these locations through this afternoon.

Dangerous marine conditions are expected to continue today into
early Friday due to the strong winds and high seas. Seas build to 7
to 12 feet on today and remain elevated into Saturday.

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

* 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.

* 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.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across the
northern shore of the Albemarle Sound. Remain well guarded against
locally hazardous flood waters having additional limited impacts. If
realized, these impacts include:
    - Localized flooding from heavy rainfall may prompt a few
      evacuations
    - Rivers and tributaries may quickly rise with swift currents.
      Small streams, creeks, and ditches may become swollen and
      overflow.
    - Flood waters may enter a few structures, especially in usually
      vulnerable spots. Rapid ponding of water is possible at
      underpasses, low-lying spots, and poor drainage areas. Some
      storm drains and retention ponds could become near-full and
      begin to overflow. Some brief road and bridge closures can be
      expected.

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