TS Laura and Marco
NOAA/NHC ^ | 21 August 2020 | NOAA/NHC

Posted on 08/22/2020 1:57:34 AM PDT by NautiNurse

The 2020 Atlantic Hurricane season continues to heat up as we are two weeks shy of average season peak activity. Two tropical systems are taking aim at the Gulf of Mexico concurrently. Tropical Storm Laura has formed east of the Leeward Islands. Marco is approaching the Yucatan Peninsula.

There is a possibility we may see the amazing Fujiwhara Effect, where two storms within 870 miles of each other will dance around each other. If one storm is significantly stronger, the weaker storm will be absorbed into the stronger storm. If the two storms are similar in size, they can gravitate toward each other until they reach a common point where they either merge or they spin each other around for a while before they spin off in different directions. The likelihood of a Fujiwhara Effect is low, however, due to the relatively small area in the Gulf of Mexico.

Laura's fate is dependent upon the extent of interaction with the tall mountains of Hispanola and Cuba.

Heads up Gulf of Mexico coastal dwellers. Unusual situation with two tropical storm systems taking aim at the Gulf of Mexico simultaneously. Could make for some interesting times next week. Perhaps we'll witness the Fujiwhara Effect? Stay tuned...

These will be a good excuse for the media to ignore the GOP convention.

“These will be a good excuse for the media to ignore the GOP convention.”

I hope someone in the WH is at least aware of the potential situation of two storms hitting in the same time frame.

This is expected when conventions are held during the active portion of hurricane season. The 2012 RNC convention in Tampa was interrupted by Hurricane Isaac. Jeb Bush did not attend the 2004 RNC in New York City while his brother was nominated for a 2nd term because of the FL parade hurricanes. There are other examples.

We live in the Texas Hill Country & we are in desperate need of rain. Marco looks like our best shot.

I’m praying he takes a trip here.

IIRC, Hurricane Hanna did not provide needed rain for your area, as the storm dipped down into Mexico.

Perhaps we'll witness the Fujiwhara Effect?

In an area as small as the Gulf of Mexico the odds are pretty good. No doubt meteorologists all over the world will be watching.

You’re correct. We live about 60 miles west of Austin. We only got 0.10” out of Hanna.

The Fujiwara was displayed on one of the models earlier this week. I think it was the GFS-parallel. Now the models are indicating a turn to the west for Marco. Not a direct hit on Houston but a landfall between Corpus and Palacios perhaps.

Marco will make little, if any, noise.

I understand your feelings. When you live in SE Texas you have too much bad history with tropical storms & hurricanes.

I lived & worked in Liberty county from ‘79 to ‘86.
We had that tropical storm Claudette dump 20 inches on us and flooded everything.

Then there was Alicia.....

But once I retired & settled in the Hill Country where my kin are from you have a different perspective.

:P That storm that just blew through wasn’t half bad. Hell of a light show closer to Austin.
