Rain and the chance of more rain across the southern parishes makes for another iffy weekend.

And with the Mississippi River on a rapid rise, and the Atchafalaya much less so, options will be limited, but don’t yet write off the Atchafalaya Spillway.

The Verret and Des Allemands basins, the marshes south of U.S. 90, the Delacroix and Hopedale areas and the canals and bayous in the southern reaches of Terrebonne Parish continue to hold the most promise for sac-a-lait, bass, catfish and redfish catches.

Constant changes and 2-4 foot seas reduce the chances to get after what’s been solid action on wahoo, amberjack and tuna catches 20-40 miles off the coast.

Weather

Friday’s 5-10 knot southeast winds and somewhat calm conditions east of the Mississippi River — expect 2-4 footers nearshore along the Central Coast — will give way to 5-10 knot northwest winds Saturday, then 5-10 knot winds from the northeast Sunday. Rain chances diminish after Thursday and Friday with morning lows in the 50s and afternoon highs near 70.

Lake Pontchartrain is predicted to settle down Saturday, but it’s likely all the rainfall in the Florida Parishes will push loads of dirty freshwater into the lake.

The Mississippi River is pushing to a 30-foot reading at Baton Rouge and to a 9.4-foot mark at New Orleans. The Atchafalaya is predicted to rise 6.5 at Bayou Sorrel and from 3.1 to 3.4 feet on the Morgan City scale.

Freshwater/the coast

You’ll have to contend with dirty water throughout the southern parishes.

Most times that means heading into canals, but there are banks in larger lakes that go unaffected by rain runoff. The good news is that Saturday’s north winds could push high rain runoff through areas after the expected Thursday-Friday heavy rains.

Another problem you’ll have to solve is that the rain and constant clouds since Sunday mean reduced hours of sunshine can’t warm the cooler rainwater that’s covering the surface of more waters.

Offsetting that will be finding points and run-outs where the weekend’s north winds will push water — and lots of food in the form of insects, baitfish, crawfish and shrimp — into ambush points for bass, sac-a-lait, catfish and what bream are making their way from wintertime homes to the banks to begin their spring feeding, then spawning rituals.

That’s why you’re likely to find boats in the canals on the east side of Lake Verret and Grassy Lake. Most reports have these canals holding clearer water than nearby bayous and rivers.

The Spillway’s south end will be the best bet.

Rain puts a crimp into speckled trout catches this time of year. That’s why redfish should be your target. Bass and redfish are in Delacroix and the Theriot area and like soft plastics.
