...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR SOUTHERN
LOUISIANA INTO FAR SOUTHERN MISSISSIPPI...

...SUMMARY...
A few tornadoes are possible mainly across parts of southern
Louisiana Friday afternoon and evening.

...Central Gulf Coast...
Hurricane Delta will move northward and make landfall on the
southwest Louisiana coast Friday evening and move
north-northeastward across central into northeast Louisiana
according to the latest National Hurricane Center forecast.  The
gradual northward advection of a very moist/tropical airmass into
southern Louisiana will occur during the day as the low-level wind
field intensifies in the northeast quadrant of Hurricane Delta. 
Forecast soundings show mid 70s F dewpoints coincident with the
development of several hundred J/kg SBCAPE with large hodographs.  A
few of the stronger updrafts within the outer bands of Delta may
intermittently acquire low-level mesosyclones and a tornado risk. 
The tornado risk will slowly spread northward during the
evening/overnight into southern MS, with the tornado threat
diminishing with time across southern coastal parishes of Louisiana
and eventually into central Louisiana during the early morning as
low-level winds veer.
