Timeline of Winds
This is crazy! The latest forecast puts the two storms about 36 hours apart from hitting southern Louisiana. Monday night and Wednesday morning!

Monday Forecast
The European Model shows both storms in the Gulf of Mexico on Monday afternoon. This depends on the forward speed for specific location. Laura would have to pass Cuba before Marco makes landfall.
Only TWO times in recorded history were there two cyclones in the Gulf of Mexico at the same time of at least tropical storm strength (winds 39 mph +):
- September 5, 1933 (Treasure Coast & Cuba-Brownsville)
- June 18, 1959 (Unnamed and Beulah)
There were NEVER two hurricanes reported in the Gulf at the same time.
Notes
Two tropical systems can not combine to a larger storm. What may happen if they get close enough is a repel or orbit governed by the Fujuwara Effect.
Hurricane Warning and Storm Surge Warning: Southern Louisiana near New Orleans appears to be the focal point for both storms within two days.
