...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...

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.
