Rain showers continue Friday afternoon through Sunday morning; threat of severe storms on Saturday
An Areal Flood Watch and a Flash Flood Watch remain in effect through the weekend, and now the Storm Prediction Center outlines a risk of some severe storms for North Alabama and Southern Tennessee on Saturday. The next two days look very wet: another 1.5” to 3.0” of rain on average (isolated spots up to 4” on top of what we already have).
Heavy rain continues through Friday evening and into Saturday morning; that round could be a real soaker putting down over an inch of rain per hour and worsening flooding conditions. In fact, NOAA’s Weather Prediction Center calls Friday morning’s situation ‘high risk’ for flash flooding in North Alabama and Southern Tennessee.
Timing the rain: Light rain showers continue to drift north through the Tennessee Valley, and at times the rain does come to a pause. However, a frontal boundary lingering south of Montgomery will continue to lift north, bringing yet more humidity into the region. This means more rain will be in the forecast through Friday evening and into Saturday morning, as outlined below.
Below shows the likelihood of excessive rainfall/flash flooding over north Alabama and southern middle Tennessee.
River flooding impacts look like this:
Tennessee River at Florence with a rise to around 23 feet through the weekend: At 21.5 feet, water covers the parking lot of the Marina at McFarland Park…with extensive flooding occurring at the soccer fields and golf course within the park. Water is also beginning to cover the road that goes underneath U.S. Highways 43 and 72 at the new playground.
Tennessee River at Whitesburg will rise to around 19-20 feet over the weekend: ‘Lowland flooding begins at 17 feet. Some access roads in the area become flooded. Water backed into Long Pond Slough begins to approach roads on the Morgan County side of the river. The entrance to the Ditto Landing area is underwater…along with much of the boat harbor. Several roads in northeastern Morgan County are underwater…and water is beginning to approach a home on River Loop Road in the Laceys Spring Community. At 21 feet, Backwater causes flooding on Redstone Arsenal. Significant flooding is occurring on the Morgan County side of the river with hundreds of acres and several homes and roads flooded.
Paint Rock River will crest near 20’ on Saturday: ‘At 19.0 feet, water is covering Alabama State Route 65 about two miles north of U.S. Highway 72. Several County Roads in Paint Rock Valley are flooded…including Jackson County Road 20.’ ‘At 20 feet, parts of Alabama Highway 65 are closed due to flood water.’
Flint River will crest around 20′ Friday afternoon: ‘At 21.0’ floodwaters reach a house trailer off of Brownsboro Road and waters likely cover Bronwsboro Road to the point that it must be closed.’
