Hmm, I'm looking at the Ventusky models and they are predicting that Marco won't even make landfall before dissipating. Marco will turn to the west over water and just dissipate before reaching land, according to the model.
But Laura looks like it will then build up steam as it comes off of Cuba and continues towards Louisiana. Wind speeds don't seem very high in the models, so Laura might barely reach Cat 1 because of the Gulf being so churned up by Marco. Plus all the rain and cloud cover will likely reduce the water temps somewhat. Heck right now here below Tallahassee the air temp is only 78 degrees, and yesterday it barely got to 75 degrees.
Well, hoping that this won't be as bad as it could be. Louisiana sure seems to get more than it's share of lumps from tropical storms.
