Signal Mountain was not immune to the outbreak of tornadoes across the area in 2011. Thunderstorms and tornadoes downed at least 75 trees across mountain roads. Shown here is the top of a telephone pole, with wires and transformer attached, that was snapped off and left dangling across a road in Signal Mountain.
National Weather Service radar shows a band of thundershowers is passing through Hamilton County headed southwest into Bradley and Polk counties bringing lightning and heavy rain.
The storms have intensified over the last 20 to 30 minutes, radar shows, although most of the precipitation is well to the north of the Chattanooga area.
