Stay updated with our live coverage as this diverse weather pattern continues to evolve:
(02:44 PM EST) Snow and Sleet in Pennsylvania:
Central Pennsylvania is currently experiencing a wintry mix of snow and sleet, causing hazardous road conditions. With up to three inches of accumulation predicted, the National Weather Service advises drivers to exercise caution on icy roads.
(02:38 PM EST) Flash Flood Alert in Tennessee:
The National Weather Service has issued a Flash Flood Warning for parts of Middle Tennessee due to heavy rainfall causing dangerous flooding. Radar images indicate more rain is on the way, with up to three additional inches expected. Residents in specific counties are urged to remain vigilant and seek higher ground immediately.
(02:24 PM EST) Northeast Wind Advisory:
Digital meteorologist Briana Waxman reports potential wind gusts of up to 60 mph across a vast region stretching from the southern Appalachian mountains to Washington, D.C., Boston, and northern New York. These intense winds are a result of rapid intensification in a process known as bombogenesis, leading to a significant pressure differential between the storm and the cold high pressure systems in the region.
(02:11 PM EST) Landslides Reported:
Two landslides have been reported due to heavy rain from Winter Storm Jett. One has partially obstructed the West Kentucky Parkway, while another has occurred in a park in West Virginia. Authorities warn that the situation remains precarious as additional rainfall may exacerbate the risk.
(02:02 PM EST) Understanding ‘High Risk’ Flood Forecasts:
A “High Risk” flood forecast signifies a high likelihood of severe and potentially life-threatening flooding. These forecasts have historically resulted in numerous fatalities and injuries, as well as substantial economic losses. Residents in areas under such warnings are advised to stay vigilant, avoid unnecessary travel, and never attempt to navigate flooded roads.
(01:51 PM EST) National Guard Deployment in Virginia:
The Governor of Virginia has mobilized the National Guard to aid in response to flash flooding caused by heavy rainfall in the southwestern region of the state.
(01:38 PM EST) Tennessee Faces Rising Floodwaters:
Reports from East Tennessee depict floodwaters rapidly encroaching on homes, underscoring the imminent threats posed by rising water levels. A flash flood warning remains in effect.
Severe weather alerts remain in effect for several counties in Tennessee as heavy rain continues to pound the region. According to the latest update at 01:25 PM EST, the forecast calls for flooding and severe weather expected today. Digital meteorologist Jonathan Belles from weather.com reports that the southern, warmer section of Winter Storm Jett is gaining strength across the South this afternoon. This intensification will enhance the influx of moisture from the Gulf into the storm, heightening the risk of severe weather later in the day. By this evening, ongoing flooding is anticipated across the mid-South, with a squall line forecasted to form stretching from Tennessee to Louisiana. The squall line is expected to bring destructive wind gusts and multiple tornadoes to the Southern states through the overnight hours.
In a separate development noted at 01:12 PM EST, parts of the Midwest are experiencing heavy snowfall from the same storm that is causing excessive rainfall in the East. Current conditions in Chicago indicate that multiple waves of snow are likely to persist through Sunday.
As states like Tennessee and Kentucky remain on high alert for dangerous flooding, it is crucial to understand flood alerts. A quick cheat sheet provided at 01:06 PM EST outlines the different flood alerts to watch for: Particularly Dangerous Situation Flood Watch indicates the possibility of widespread significant flooding, while a Flood Warning signifies that water levels are rising with a threat to life and property. A Flash Flood Emergency is issued when life-threatening flooding is occurring or imminent. These alerts have either been issued or are potential for parts of the U.S. throughout the day and into the night.
At 12:59 PM EST, reports of serious flooding have started to emerge from Kentucky as heavy rain continues to cause havoc. In Corbin, Kentucky, police have been forced to close streets after at least one car got stuck in floodwaters. Near the Tennessee border, in Guthrie, Kentucky, videos show rushing waters engulfing streets and yards, highlighting the dire situation unfolding in the region.
