Tropical system to bring heavy rainfall to Louisiana
Posted on 6/20/2017 11:36:00 AM.

Tropical Storm Cindy could drop a foot of rain in southeast Louisiana. State climatologist Barry Keim says the system is expected to make landfall as a tropical storm near the Texas-Louisiana border late Wednesday or early Thursday morning, but the largest rain totals will occur to the east of the storm’s center.

“We can expect between 6 to 9 inches of rain in southeastern Louisiana, southern Mississippi, and south Alabama, with isolated totals between 10 and 15 inches,” Keim said.

Flash flood watches are in effect across south Louisiana through Thursday evening. Keim says storm surge could be an issue in coastal areas, and it’s possible a tornado could form. But he says rain and potential flash flooding will be the biggest problems.

“The rainfall is going to be the biggest issue. Flash flooding certainly could be a problem. We could get flooding on some of the major river systems with these kinds of rain volumes,” Keim said.

Keim says the heaviest rains are expected in southeast Louisiana, but the entire coast is vulnerable. He says that’s because the major rainfall associated with this system is far removed from the center of circulation.

“Even though it’s going to come on shore near the Texas-Louisiana boundary, the biggest impacts are likely to appear more in southeastern Louisiana and on towards Florida with that heavy rainfall,” Keim said.
