Weather Alerts For Walland, TN

# HEADLINE -------------------- FLOOD WATCH IN EFFECT FROM 7 AM EDT THIS MORNING THROUGH THIS AFTERNOON # DETAILS -------------------- WHAT Flash flooding caused by excessive rainfall is possible. WHERE Portions of east Tennessee, including the following areas, Anderson, Blount Smoky Mountains, Campbell, Claiborne, Cocke Smoky Mountains, Grainger, Hamblen, Hancock, Hawkins, Jefferson, Johnson, Knox, North Sevier, Northwest Blount, Northwest Carter, Northwest Cocke, Northwest Greene, Scott TN, Sevier Smoky Mountains, Southeast Carter, Southeast Greene, Sullivan, Unicoi, Union and Washington TN and southwest Virginia, including the following areas, Lee, Russell, Scott VA, Washington VA and Wise. WHEN From 7 AM EDT this morning through this afternoon. IMPACTS Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. ADDITIONAL DETAILS - Additional showers and storms are expected to spread into the area this morning into the early afternoon. Due to recent rainfall, poor antecedent soil conditions will lead to heightened chances for localized flash flooding with this additional convection. - http://www.weather.gov/safety/flood ISSUED AT Wednesday, August 12, 2026 at 2:38 AM EDT ISSUED BY National Weather Service Morristown TN HEADER URGENT - IMMEDIATE BROADCAST REQUESTED | Flood Watch # PRECAUTIONARY/PREPAREDNESS ACTIONS -------------------- You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. # AREAS AFFECTED -------------------- Anderson, Blount Smoky Mountains, Northwest Carter, Wise, Campbell, Claiborne, Cocke Smoky Mountains, Grainger, Hamblen, Hancock, Hawkins, Jefferson, Johnson, Knox, Lee, North Sevier, Northwest Blount, Northwest Cocke, Northwest Greene, Russell, Scott TN, Scott VA, Sevier Smoky Mountains, Southeast Carter, Southeast Greene, Sullivan, Unicoi, Union, Washington TN, Washington VA Including the cities of Dandridge, Pigeon Forge, Kingsport, Knoxville, Rose Hill, Oneida, Castlewood, Wise, Hartford, Norris Lake, Gatlinburg, Dye, Elizabethton, Kodak, McMahan, Pardee, Hampton, Royal Blue, Clinton, Paulette, Greeneville, Abingdon, White Pine, Limestone Cove, Benhams, Chestnut Hill, Lebanon, Appalachia, Elk Valley, Caryville, Laurel Bloomery, Harrogate-Shawanee, Happy Valley, South Holston Dam, Alpha, Sevierville, Bristol TN, Jefferson City, Evanston, Coeburn, Mountain City, White Oak, Doeville, Luttrell, Strawberry Plains, Norma, Howard Quarter, Smokey Junction, Rosedale, Springdale, Unicoi, Harrisburg, Hiltons, Oak Ridge, Trade, Morristown, Norton, Big South Fork National, Sharps Chapel, La Follette, Russellville, Treadway, Bybee, Shady Valley, Huntsville, Sneedville, Honaker, Clairfield, Hansonville, Maryville, Mooresburg, Bristol VA, Elgin, Johnson City, Slick Rock, Kyles Ford, Erwin, Arthur, Big Stone Gap, Newport, Bean Station, Lone Mountain, Maynardville, Alcoa, Sandlick, Jellico, Neva, Bearden, Elkmont, Fincastle, Cedar Creek, Cades Cove, Lake Forest, and Seymour

Closest strike: 28.14 miles Monitor Storms You are not at immediate risk, but frequently check WeatherBug to see if storms are moving towards you. Be aware that new storms can also form with little notice.

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE NORTHERN/CENTRAL PLAINS TO THE LOWER OHIO VALLEY SUMMARY Thunderstorms with severe gusts and hail will be possible this afternoon and evening across parts of the central and northern High Plains. Damaging gusts and isolated hail will also be possible across parts of the Midwest and Ohio Valley. IA to OH Valley One or more MCSs migrating through enhanced northwesterly flow aloft amid a very moist and unstable airmass is possible again today across the Midwest toward TN. Most forecast guidance suggests an MCS or thunderstorm clusters could be ongoing over IA at the start of the period (12z), with warm advection storms arcing across parts of IL/IN. The early day warm advection storms could develop southeast across the OH Valley, while the IA MCS develop southeast across the Mid-MS/Lower OH Valley through afternoon. The exact evolution of convection that is not yet apparent is uncertain, and how outflow may influence how this activity evolves through the afternoon. Regardless, the overall environmental parameter space will be favorable for a damaging wind and isolated hail risk through early evening. Northern/Central Plains East/southeasterly low-level flow will maintain modest moisture across the Dakotas, increasing with southward extent across NE into northern KS. Near-60 F dewpoints will likely spread westward into eastern CO/WY/MT. Modest moisture beneath steep midlevel lapse rates and 30+ kt effective shear magnitudes will support scattered thunderstorm development across the High Plains. Initial cells will pose a large hail and damaging wind risk. It is unclear how convection will evolve with eastward extent across the region as outflow from prior convection may largely limit stronger destabilization. A developing low-level jet during the nighttime hours will be focused across the southern Plains toward KS/southern NE. This could support some upscale growth potential, but confidence is low. Lower MI into NY/PA/NJ A belt of stronger northwesterly flow aloft will extend from Lower MI into NY/PA today. A seasonally moist/unstable airmass will be in place. Vertically veering wind profiles will foster 35+ kt effective shear magnitudes, while hodographs are fairly elongated. Midlevel lapse rates will remain modest, with MLCAPE around 1000-1500 J/kg expected. Isolated to widely scattered storms will pose a risk for damaging gusts and small hail. TN Valley/Southeast Thunderstorms are expected to develop by midday within a very moist and strongly unstable airmass. Deep-layer northwesterly flow will remain weak, but steep low-level lapse rates and PW values near 2 inches could support isolated wet microbursts with stronger multi-cell clusters.
