A broad area of tropical moisture will move onshore Sunday morning and continue on and off throughout the day and linger into Monday.

The heaviest showers/storms will arrive first thing Sunday and be fairly steady through lunchtime before we get a break during the afternoon.

Another wave of heavy showers/storms is expected to swing through Acadiana on Monday morning.

In total the models are forecasting 2-4 inches of rain the next couple days, while a few spots could see higher amounts in the 3-6+" range.

For this reason most of Acadiana is under a flash flood watch until Monday afternoon when the tropical moisture should finally lift out of the area.

Tuesday we go back to a typical summertime pattern with partly sunny skies in the morning followed by hit or miss showers and storms in the afternoon.

A cool front is then projected to swing down through Acadiana Wednesday afternoon/evening producing another round of showers and storms.

The good news is this front looks to push out into the Gulf finally ending this rainy pattern and provide us some beautiful sunny days with low humidity Thursday through Saturday.

Beyond Saturday there is some questions in the forecast for Sunday and Labor day as the models are indicating that a tropical wave could move into the Gulf but the drier air might keep most of the moisture just to our East towards New Orleans and the Mississippi Coast.

And speaking of the tropics things are heating up.

Tropical Storm Dorian has formed in the open Atlantic.

Dorian is forecast to slowly strengthen as it heads for the Lesser Antilles island the next few days.

After crossing into the Caribbean Tuesday afternoon Dorian should become a hurricane as it marches towards Puerto Rico or the Dominican Republic.

Beyond that the models have the system weakening but could become the tropical moisture that I was talking about that might enter the eastern Gulf by Labor Day.

Also, the National Hurricane Center is keeping an eye on an area of showers and storms off the east coast of Florida.

This wave has a 70-90% chance of becoming a tropical depression of tropical storm in the coming days but the good news is this disturbance should remain offshore and turn away from the east coast.
