SITUATION OVERVIEW

------------------



Tropical Storm Idalia will continue to push farther offshore today. 

The flooding rain and tornado threats have come to an end, but the 

threat for gusty winds continues. Ongoing gusty winds and saturated 

soils may lead to some downed trees and power lines.



POTENTIAL IMPACTS

-----------------



* WIND:

Potential impacts from the wind event are continuing across coastal

areas north of Cape Fear. Remain well sheltered from hazardous wind 

having possible limited impacts. If realized, these impacts include:

    - Damage to porches, awnings, carports, sheds, and unanchored 

      mobile homes is possible. Unsecured lightweight objects may be 

      blown about.

    - Some large limbs may break from trees. A few shallow rooted or 

      weak trees may snap or be knocked down. Some fences and roadway 

      signs damaged.

    - A few roads may become impassable due to debris, particularly 

      within urban or heavily wooded locations. Hazardous driving 

      conditions are possible, especially for high profile vehicles 

      on bridges and other elevated roadways.

    - Scattered power and communications outages are possible.



Elsewhere across southeast North Carolina and northeast South 

Carolina, little to no impact is anticipated.



* SURGE:

Potential impacts from the surge event are continuing across coastal 

areas north of Cape Fear. Remain well away from locally hazardous surge

having possible limited impacts. If realized, these impacts include:

    - Localized inundation and minor over-wash is possible, mainly 

      along immediate shorelines and other vulnerable low-lying areas 

      along the coast. Low spots along waterways and tidal creeks may 

      also be impacted.

    - Some portions of near-shore roads and parking lots may become 

      covered by surge water. Driving conditions may become hazardous 

      in places where the surge covers the road.

    - Moderate beach erosion is possible, mainly in the vulnerable 

      locations along the ocean front.

    - Minor damage to marinas, docks, boardwalks, and piers is 

      possible. A few small craft may break away from moorings if not 

      properly secured.

    - Navigation may be difficult near inlets and waterways, as 

      navigational aids may be off station or missing.



Elsewhere across southeast North Carolina and northeast South 

Carolina, little to no impact is anticipated.



PRECAUTIONARY/PREPAREDNESS ACTIONS

----------------------------------



* OTHER PREPAREDNESS INFORMATION:
