Although Barry continues to weaken, dense bands of showers will continue to produce life-threatening flash flooding across portions of the Mississippi Valley.
As of 10 a.m. CDT, Post-Tropical Cyclone Barry was located near 39.0 N and 91.3 W, or about 50 miles west north-west of St. Louis. Barry has maximum sustained winds at 15 mph and is accelerating northeast at 21 mph. The minimum central pressure of the system continues to be 1011 mb, or 29.86 inches of mercury.
Despite weakening, Barry will continue to produce life-threatening flooding across portions of Arkansas today as heavy rain moves into the Ohio and Tennessee valleys. Rainfall totals of 2 to 4 inches will accumulate across southern Illinois and southern Indiana, with higher totals as high as 5 to 10 inches drenching southern Arkansas, the Missouri Bootheel, northern Mississippi and western Tennessee.
Flash Flood Watches span from extreme northeastern Texas into southern Arkansas and southeastern Missouri Illinois, and far western Kentucky and Tennessee. These watches will likely expand into the Ohio Valley and interior Mid-Atlantic as Barry’s moisture will get caught up in the jet stream or upper-level winds and sweep east along Interstate 70 today into Wednesday. A few inches of rain falling on already saturated ground could lead to flash flooding. Remember, if you approach a flooded road, “Turn Around, Don’t Drown!” as water is usually deeper than it appears.
Since Barry came ashore in southern Louisiana Saturday morning, it has dropped 2 to 8 inches of rain, with localized totals as high as a foot.

Berwick, La., had a peak gust to 63 mph, Lafayette, La., at 52 mph while New Orleans saw a peak gust of 40 mph.
