The National Weather Service has issued a ***FLOOD WATCH*** for East Baton Rouge, West Baton Rouge, Ascension, Assumption, Iberville, East Feliciana, Livingston, Pointe Coupee, St. Helena, St. James, Tangipahoa, and West Feliciana Parishes. It will go into effect Wednesday afternoon and last through Friday night. A FLOOD WATCH means conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. Be on the lookout for threatening weather conditions and listen for later statements and possible warnings. For more on flooding safety, CLICK HERE.

Tonight: Rich, tropical moisture will move into the atmosphere on Wednesday night. As this occurs, clouds will thicken and isolated showers and thunderstorms will be possible with an increase in rain coverage with time. Due to the tropical moisture, it will stay warm and muggy with lows in the upper 70s.

Thursday & Friday: A weak tropical disturbance will influence local weather on Thursday and Friday. Associated moisture will lead to a couple of days in a row with very high rain coverage. Largely manageable rainfall totals of 2–5" are likely, with locally higher amounts possible, especially near the coast. Some bullseyes near 8" will be possible, and in these locations, isolated flash flooding may occur. Exactly where the heaviest rain falls will not be clear until the bursts of activity begin to develop over land. Each day, highs will stay in the upper 80s due to cloud cover and precipitation. 

Up Next: Over the weekend, the tropical moisture will slowly begin to depart, leading to a gradual reduction in rain coverage. Of the two days, Saturday will be busier with scattered showers and thunderstorms enhanced by daytime warming. Sunday will only have isolated activity, allowing high temperatures to climb back well into the 90s. Next week looks like a return to average summer weather with heat, humidity, and pop-up, afternoon thunderstorms. 

The Tropics: Surface and radar observations indicated that a westward-moving broad area of low pressure continued to be located near the coast of the western part of the Florida Panhandle. The associated shower and thunderstorm activity remained disorganized and located south to southwest of the center. This system is forecast to continue moving westward across the northern portion of the Gulf and is expected to reach the Louisiana coast by Thursday. If this system moves far enough offshore, environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could form over the next day or so before the system moves fully inland by the end of the week.
