Isolated flash and urban flooding possible across portions of Louisiana
mid-week...

Periods of moderate to locally heavy rainfall will return to portions of
the Gulf Coast Region and Southeast beginning Wednesday, bringing an
isolated potential for flash and urban flooding across southern LA
Wednesday into early Thursday. Soils are now primed for hydrologic
responses following multiple rounds of rainfall over the past several days,
suggesting an increased vulnerability to efficient runoff into nearby urban
drainages and streams. However, streamflows are at or below annual means
for this time of year, suggesting sufficient channel storage capacity for
runoff and largely mitigating flooding impacts. Pluvial ponding and
standing water in typical flood-prone and urban areas are possible, with
the greatest potential in urban areas along the I-10 corridor.
