Just one more day of rain and then Baton Rouge and Lafayette at least will see blue skies, sunshine and warm temperatures again — just in time for many St. Patrick’s Day festivities.

A slight chance of rain remains in the forecast for New Orleans on Saturday, but only about 20 percent.

Cloudy skies will arrive Saturday morning, with temperatures reaching 77 degrees in Baton Rouge, 74 degrees in Lafayette and 71 degrees in New Orleans.

However, the rainfall around south Louisiana on Friday means that a flash flood watch will remain in place for Baton Rouge and New Orleans until 6 p.m. Friday and until 1 p.m. Friday in Lafayette.

As of Thursday afternoon, the forecast said areas of south Louisiana could get three to six more inches of rain on Thursday and Friday as waves of heavy rainfall continue to come through the area from the Gulf of Mexico, according to the National Weather Service in Slidell.

As of Thursday afternoon, the rainy week doesn’t appear to have resulted in widespread flooding across south Louisiana. There have only been two spots along the Pearl River reporting river stages that qualify as minor flooding.

“The nice thing about this rainfall is that it’s been really spread out,” said Suzanne Van Cooten, hydrologist in charge at the National Weather Service Lower Mississippi River Forecast Center in Slidell.

The timing between waves of rainfall into south Louisiana means the rain that falls has time to drain off or soak into the ground before the next rainfall arrives.

“That’s really helping us a lot,” Van Cooten said. “We’re doing pretty good so far.”

Some rivers will experience their most dramatic rise following rainfall that’s expected to arrive Friday.

The Amite River at Denham Springs, for example, was forecast to rise more than 11 feet between Thursday afternoon and Sunday evening, topping out at 27 feet. However, that’s still below the minor flood stage of 29 feet at that location, according to the National Weather Service.

As the water continues to rise, concern of minor flooding is expected to arrive at the Tangipahoa River at Robert on Saturday morning. The Tangipahoa River is expected to reach its highest level Saturday evening at 16.5 feet before starting to fall.

The impact at that level includes some minor flooding near the river and possibly some flooding along La. 22 south of Robert, according to the National Weather Service.

All of that could change if an area gets more, or less, rain than expected or if that rainfall falls in a shorter period of time than has been occurring this week, Van Cooten said.
