...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
EASTERN NORTH CAROLINA AND CENTRAL VIRGINIA...

...SUMMARY...
A tornado threat is expected to develop today from parts of eastern
North Carolina into central Virginia.

...Eastern North Carolina/Central Virginia...
Tropical Storm Debby will move northward across eastern South
Carolina today and into southern Virginia by this evening. Rainbands
associated with Debby are forecast to move from North Carolina this
morning into Virginia by afternoon. Although the strongest
destabilization is expected in the coastal areas of eastern North
Carolina and southeastern Virginia, the strongest low-level winds
associated with Debby are forecast to be further to the west. RAP
forecast sounding along the path of the strongest low-level winds
have 0-3 km storm-relative helicity in the 200 to 300 m2/s2 range
with precipitable water values above 2.5 inches and MLCAPE around
1000 J/kg. This should be favorable for a tornado threat, associated
with the more discrete storms embedded in the rainbands of Debby.
The tornado threat is expected to continue this evening, as Debby
approaches southern Virginia, and gradually weakens in the process.
