The National Hurricane Center is tracking three tropical waves, including two in the Caribbean. Tropical wave 1: A far eastern Atlantic tropical wave is near 30W from 17N southward, and moving west at 11 mph.

"A sizable zone where 4-8 inches of rain is forecast to fall extends across much of the southern half of Louisiana and part of southern Mississippi. Within this zone, pockets where 8-12 inches of rain can fall are anticipated with an AccuWeather Local StormMax rainfall of 16 inches."

We could see the fourth named tropical system of the season later this week. Heavy showers and storms expected, regardless.
