Memorial Day weekend is typically the start of climatological summer here in Louisiana. And the start of tropical activity. While it's still early for development of named storms, it's still possible for tropical depressions to form. In fact, we might just have one for the start of Memorial Day weekend.
A broad, monsoonal-type disturbance in the Caribbean is expected to move into the Gulf later this week. Two models - GFS and Euro - call for northward movement and increased flow of moisture. But the Euro model calls for some development and a more northwestern path. At the least, it could mean a significant rain event for south Louisiana.
Memorial Day weekend is one of the busiest fishing periods of the year. Expect everyone to keep a close eye on this disturbance.
