Areas affected...eastern Mississippi into Alabama...western Florida
Concerning...Tornado Watch 475...
Valid 302013Z - 302215Z
The severe weather threat for Tornado Watch 475 continues.
SUMMARY...Conditions remain sufficiently favorable for a tornado
risk in association with Ida. The primary risk area appears to be
from eastern Mississippi into western Alabama.
DISCUSSION...Three primary bands of convection persist from MS into
AL and the FL Panhandle this afternoon. The middle band has been the
most productive in terms of tornado risk, but has lost intensity
with time as it translated east into central AL. Widespread rain is
likely limited potential here.
To the east, scattered storms persist across southeast AL and into
the FL Panhandle. Here, instability is maximized, but this area is
on the eastern fringe of the more favorable shear. As such, the
tornado risk here may remain low.
In the near term, the most favorable area may be with a newly
developed band consisting of broken cells over far eastern MS. The
environment here consists of 250+ 0-1 km SRH, as well as a narrow
sector of recovering air mass out of the southwest. This may yield a
tornado risk which may shift again into parts of AL.
