in poor drainage and urban areas. Low-water crossings may be
flooded. Extensive street flooding and flooding of creeks and
rivers are possible.

* ADDITIONAL DETAILS...
- An early season back door cool front will interact with a late
season plume of deep tropical moisture, bringing several rounds
of thunderstorms with torrential downpours to the region Tuesday
afternoon through Wednesday evening. Repeated thunderstorms may
tend to focus in one or two areas, resulting in higher end
precipitation totals. The most critical period with the heaviest
rain potential will likely be Tuesday night into Wednesday
morning.
