It is the highest risk that the Weather Prediction Center issues for forecasting flooding. High water and quickly-rising water will be likely through Saturday night. Avoid flooded roads, consider avoiding travel and listen for any further alerts/actions. The rainfall forecast from Saturday night through Sunday night calls for an additional 2-4" in yellow and orange colors with isolated amounts up to 5" in the red colors. As a result of the heavy rain the past week, flash flood alerts will continue through the rest of the weekend along the northern Gulf Coast states. Previous Update Below: Flooding is a continued concern in the South as waves of thunderstorms move across the region. https://twitter.com/i/status/1127163824585359360 Flash flooding has been a major issue through Louisiana and Texas will continue to be the biggest threat with rain expected to linger this weekend. Flash Flood Watches are in effect from Alabama to Texas. The potential for excessive rainfall extends across most of the South for today (Saturday). Humidity levels in the atmosphere will remain high, with moisture flowing northward across the Plains from the Gulf of Mexico. Jet Stream energy will be persistent with a deep trough in the atmosphere. This will keep storms traveling over the same areas, which will likely create over-saturated soils, increasing the threat for flooding. Flooding concerns will continue into the weekend. The excessive rainfall forecast from NOAA's Weather Prediction Center shows a continued risk for heavy rain and flooding from the Middle Atlantic to the Mississippi Delta.
