...NWS Damage Surveys Thursday 1/19 through Sunday 1/22...
...Confirmed tornadoes now up to 11 tornadoes in Central Alabama....

.OVERVIEW...

A deepening upper low sent several impulses over Central Alabama
Thursday through Sunday. Each impulse was able to pull moisture
northward and into Central Alabama. Conditions became unstable as
the moisture, warm surface conditions, cold upper level conditions,
and wind shear combined to initiate severe thunderstorms. Numerous
storms developed in association with each wave. The southern half
of Central Alabama was most impacted. Tornadoes, damaging winds,
some hail, and localized flooding occurred. The events below are
from the Thursday through Sunday timeframe.

End Lat/Lon:            33.4877 / -86.3025

Survey Summary:

A persistent mesocyclone spun up a brief weak tornado within a
line of thunderstorms as it passed through St Clair County.  The
tornado touched down on Logan Martin Lake just south of the
eastern shore of Treasure Island.  The tornado tracked northward
parallel to and just off the shores of the island, with the initial
damage pointing largely offshore.  Four boathouses were destroyed
and a few trees were snapped or uprooted here, but the path of the
tornado was far enough offshore so as not to cause any structural
damage to the homes another 50 to 100 feet further inland.  As the
tornado continued northward across a large cove, it remained
completely over water. As it approached the northeastern tip of
the island, which jutted out into the lake, the tornado came ashore
again and peeled metal roofing off a well-built boathouse.  The
tornado reached maximum strength here, with 10 large hardwood trees
uprooted in a concentrated area in a convergent pattern.  The
tornado passed offshore again and dissipated before reaching the
opposite point on the lake. A special thanks to the St. Clair County
Emergency Management Agency for assistance.

A storm survey was conducted in Blount County, with a particular

and the absence of debris splatter on the leeward facing sides of
the damaged structures. In the immediate downtown area, over 60
structures were damaged or destroyed and approximately 200 trees
were either snapped or uprooted. The peak wind speeds were estimated
between 70 and 80 mph, and this was confirmed by a weather observation
