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.

Good one,everyone wants a piece of Trump it's unreal sometimes.

The rats are super dirty once they do get power.

The one in Key West, a lezzie mayor, somehow managed to get the majority of 3,800 write in votes to win a 3-way election going away. We suspect many were out of state with out of state voters miraculously all claiming Key West as their home town so they can vote here.What a coincidence....!!The gay power of Key West is unbelievable but sadly real.

This after trying her best to destroy the city of Key West which is a virtual ghost town at this point. Over 100 small businesses already gone out of business and more expected to go

This one is vindictive as well.If you cross her expect the gendarmes to visit your business or home in short order. We are up against a budding commie venue that will stop at nothing for sheer power over us.

It's not likely Key West or much of the Keys will see much from either storm but just to make sure the economy takes yet another dive the Key West mayor ordered tourists out and those in trailers,boats gone along with vehicles with height to leave.Just sort of rubbing it in that she can pretty much do whatever damage she wants with no one saying anything for a variety of reasons.

August ,Sept. and October are dead months for most businesses anyway down here,seems the mayor wants to make sure they are even worse than normal.She doesn't need or want capitalism for sure.

At least we get to blast her every Wednesday from Two Friends Patio Restaurant in key west as three of us shout out the voices of Conservative freedom on two stations across the keys on another edition of Keys Talk Radio. Our show is heard on 97.7 in the Lower keys and 103.1 in the Upper Keys and South Miami from 8-9 am Eastern.

Bad topic for me. If you look at Puerto Rico and then Fla.Bay all you see are buoy after buoy.Than look at offshore of South Eastern Fla. one of the busiest boating areas in the country and you are hard pressed to find a buoy especially one that works.

Meanwhile 20-30 miles north of the reef in Fla. Bay there is buoy after buoy where no one goes,go figure.This is what happens when govt., especially big govt. does stuff that we(private enterprise) should be doing.

My bet is Trump will fix all this in his second term,he can not be fooled.

Great to hear the radio waves carry conservative talk throughout the FL Keys! Thank you for all you do to get out the message!

Whoa, Nelly. And here it looked like we were gonna dodge two bullets. Gotta get back outside and try to get the yard work finished, before one or both pull another Crazy Ivan and track any further east. We may be getting a spot of weather after all.

The Fujiwhara effect should push the storms counter-clockwise when they are this close. That's from this paper http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.395.2813&rep=rep1&type=pdf You can see 600 nm is rare but not unheard of. It's a limited dataset but CCW motion means the first storm turns left and the second turns right as shown in the current run of the euro.

Last evening our local meteorologist said the Fujiwhara potential was low because of the small area in the Gulf of Mexico.

Maybe he thinks land interaction will affect steering more than the Fujiwhara effect.

They can't merge or spin around each other. That just does not happen, see the link I posted.

Latest projections have Marco making landfall in Louisiana when Laura is still over Cuba.

600 miles or so, close enough for some Fujiwhara effect. It would make the first storm turn left and the second storm turn right.

Thanks for the moral support, at least. The battery in the cordless weed trimmer went low; two other trimmers need string; the gas powered trimmer hasn't been started in two years; the grass in back was so high it overheated the drive belt on the riding mower and stalled in place (note to self: fix that other riding mower STAT); and I need to untangle the knot of outdoor cord to use the hedge trimmers. That left the push mower but I forgot to take a Benadryl before I started and broke out in hives so big, I looked like I was stung by hornets. (And they itched like crazy.) I just left things as-is, took a shower, started a BBQ chicken dinner, and voluntold the wife she's not going to spend the day tomorrow beached on the sofa and binge-watching any of her shows, she's getting out there and working up a sweat with me. I'm on disability anyway and an acre and a quarter is a pretty formidable opponent if you try to do it solo and get it all done right, even if you have gas and power tools out the tuckus and a lawn tractor with a big deck.

Yes, the very experienced meteorologist indicated that land interaction would most likely inhibit the Fujiwhara potential. He described the effect would be more pronounced in a larger body of water (eg ocean).

I should amend what I said above. The Fujiwhara effect shows up in some hurricane interaction and the link I posted shows that, but none making even a half rotation. However the spinning and merging does happen with cold core lows in the ocean SE of Greenland and over the Aleutians. I think the differences between warm and cold core storms probably accounts for the difference in behavior.

Oh, boy! This situation looks like a doozy.

Unprecedented?

I don’t like that word, when hurricanes are involved.
