999 AGUS74 KWCO 011255 HMDNWC National Hydrologic Discussion - EXPERIMENTAL NWS National Water Center - Tuscaloosa AL 700 AM CST MON DEC 1 2025 Update... No major changes to the FHO for day one. American Samoa remained highlighted as flooding concerns will continue through the morning (local time); however, flooding concerns may diminish as the day continues. //Smith Previous discussion as follows ...Isolated flash flooding impacts remain possible across American Samoa through the rest of today... Isolated flash and urban flooding is possible across southeast Texas and southern Louisiana on Monday and again late this week...[Rainfall impacts the Southeast and Mid-Atlantic this weekend into early next week...] American Samoa... Periods of heavy rainfall will continue through tonight (local time), likely leading to isolated flash flooding impacts across the islands. Southeast Texas and southern Louisiana... Moderate to locally heavy rainfall will return on Monday, bringing the risk of flash and urban flooding back to the area. Last night and this mornings rainfall has helped to moisten topsoils (NASA SPoRT) and limit available infiltration capacity for the next round of rainfall. Most streamflows are still running below normal, outside of the Houston area, which remain near normal. Confidence in widespread flooding impacts remains low, but isolated flash and urban flooding will still be possible, particularly along the I-10 urban corridor. Additional rounds of rainfall are forecast late this week, starting on Thursday and will bring back concerns for flash and urban flooding to the region. Southeast and Mid-Atlantic... Moderate to locally heavy rainfall will spread into the Southeast later on Monday and into the Mid-Atlantic on Tuesday. Confidence in flooding impacts remains low given drier soils (NASA SPoRT) across these regions, but localized nuisance/urban flooding will be possible with any heavy rainfall that moves through urban areas. //JAW Additional National Water Center products are available at www.weather.gov/owp/operations $$
