BATON ROUGE, La. (WAFB) - The threat for heavy rain which could lead to localized flash flooding will be increasing in the coming days. Moisture levels in the atmosphere will continue to increase allowing for the potential for heavy rain showers.

WAFB's Jeff Morrow gives an update on what they're tracking next with potential floods in the next couple of days.

The Weather Prediction Center has outlined Wednesday and Thursday as days we will have to be on the look-out for localized flash flooding. Flooding would generally be of the nuisance variety (i.e. roads, ditches, steams, bayous).

A Marginal Risk for flash flooding remains in effect for Thursday. The heavier rain threat will be tied to a passing tropical wave in the Northern Gulf of Mexico. This wave will bring a surge of tropical moisture and added lift to the atmosphere prompting widespread rain coverage.

The end of the week will see high pressure try to build in from the west. Drier air will also attempt to move in from the north as a trough deepens along the East Coast. This will cause a slight reduction in rain chances by the weekend and for the first part of next weekend.
