Tropical Storm Marco is a little stronger at 8AM EDT Saturday. However, a 30-40 knot southwest upper shear band is ahead across the central Gulf of Mexico. Marco will need to fight through that shear to survive. Tropical Storm Laura is forecast to track west-west-northwest across Hispaniola and Cuba over-the-weekend which is a tough course to follow to survive due to the high terrain. HOWEVER, if each storm survives these obstacles the super warm Gulf of Mexico could allow strengthening to a hurricane before eventual landfall in the north or northwest Gulf of Mexico.
