...River flooding becoming less likely across Southeast Louisiana
and Southern Mississippi...

Tropical Storm Harvey has become stationary over Southeast Texas
in close proximity to the Houston metropolitan area. Catastrophic
flooding is currently underway where over 2 feet of rain has
occurred in several locations with more heavy rain yet to occur.
The heaviest rains thusfar have remained well west of the local
forecast area of Southeast Louisiana and Southern Mississippi.

Looking ahead, there still remains a chance for narrow bands of
tropical showers and thunderstorms to develop at times between
today and Thursday before Harvey finally lifts out of the region
later this week. Rainfall accumulations generally between 2 and 5
inches is now indicated over the next 5 days, with the lower end
likely over the Mississippi coastal counties, the higher end of
the range over east-central and south-central Louisiana, closer to
the influences of Harvey.

If these rainfall amounts materialize and are spread over several
days, the area rivers and streams should be able to handle that
capacity without experiencing flood conditions.

The situation will continued to be closely monitored and assessed
over the next several days, as the erratic nature of Harvey and
its rainfall pattern maintains a high degree of uncertainty still.
Continue to stay aware of the latest forecasts and happenings with
Harvey this week.
