Sirens Herad in Cartersville

From John Sepulvado: Sirens just blared throughout Cartersville a few minutes ago as dark clouds moved into the area. We'll update ASAP on whether those were, in fact, tornado sirens.

UPDATE: Locals say they were sirens, no word yet from local officials. The thunder sounds like the sky is breaking.

UPDATE 2: In Floyd, tornado warning in effect with reported funnel cloud in Menlo.

Here's some of the reports.
