ATL: Marco : Tropical Depression - Discussion

[HURAKAN]

Here is a question for the pro-Mets, could Marco have been a TD last night over the southeastern part of the Yucatan Peninsula before moving over the BOC?

[Category 5]

Another question, will they considered this as tied with Monica for smallest TC on record?

Monica? Isn't Tracy the smallest?

[HURAKAN]

More or less!!!

probably

[HURAKAN]

Another comparison. Enjoy!

[Cyclone1]

Okay... this is the first time I've seen teh storm since it's formation so let me get my hurricane dorkatude out of the way. *ahem8

WHAAAAAT?! THIS THING IS MICROSCOPIC! WHEN DID THIS FORM!? HOLY....

*ahem*

Okay you may continue posting.

[CrazyC83]

Marco's entire circulation could fit in Ike's RMW at its peak...

[HurricaneRobert]

Not the first midget Marco.



Too bad they didn't have two earlier East Pacific storms. Then this would've been Marco and the other side of Mexico would've had Polo.

This is why RECON is so important. Big difference between 2.0 and 3.5.

1007 to 998. Slight tick more N.

I would assume it's because dvorak technique doesn't work on tiny systems like Marco very well.

RAW has been doing excellent.

[O Town]

Wow, kinda surprised to see this is a TS. Its so tiny.
Cute lil' guy ani't he....

[Epsilon_Fan]

awwwwwwwwww

It's funny that you are a letter swap away from TS MACRO, when it's this tiny it should probably be TS MICRO. haha

maybe this will crank into a itty bitty hurricane

[HURAKAN]

Histories Mysteries: "Marco, a tropical cyclone or an oversized waterspout?

[Cyclenall]

This is the smallest Tropical Storm or Tropical Cyclone for that matter I have ever seen!!! They should call this storm tropical storm MICRO! I'm thankful recon was able to get in to measure the windfield! Thank you recon crew!

[jinftl]

Small systems like this can spin up very quickly.....a 30-mile swath of even sustained 55 or 65 mph winds can do a significant amount of damage to trees, powelines, etc. Not to mention the possibility he could even become a Cat 1 before landfall (NHC puts that at 26% probability during next 24 hours...even a 2% probability of a Cat 2....not too shabby for something that wasn't even an invest earlier today... as of 5pm advisory-see Wind Probability section of advisory).

Marco may not effect a large area, but he could pack quick a punch where he does.


Interesting discussion from Dr. Jeff Masters:

Surprising Tropical Storm Marco has burst onto the scene in the extreme southern portion of the Gulf of Mexico. In just five hours, the tiny storm has spun up to near hurricane strength, a remarkable rapid intensification feat. Visible satellite loops show a tiny storm with a concentrated area of heavy thunderstorms, moving west-northwest at about 10 mph. In another example of why we need the Hurricane Hunters, an Air Force airplane that scrambled to fly Marco with little advance notice found top winds of 65 mph and a 998 mb pressure at 4:19 pm EDT. Satellite estimates using the traditional Dvorak Technique were still classifying Marco as a tropical depression with 35 mph winds this afternoon.

I had to hide the plane and use the track only on some of the recon graphics because it was covering up parts of Marco.

[HURAKAN]

jinftl, operational Marco went from TD to TS in almost no time, but I expect the NHC to say that Marco was a TD last night and became a TS this morning, and it intensified rapidly but not so sudden.

For example, look at these loops. Last night over land and today over water. The same system.
