Tropical Storm Marco

A tropical depression has formed from invest 96L which has emerged in the Bay of Campeche. TD13 consists of a small LLC with a deep but limited coverage of convection. This tiny system has potential to strengthen into a tropical storm before landfall, as outflow is good and sea temps warm. However, what TD13 is lacking is time. The depression will make landfall on the coast of Mexico tomorrow, so a peak of 40kts is all NHC are forecasting. The depression is small, so will respond to favourable condtions quickly, so the forecast of 40kts is more than achieveable.

TD13 is the small circular blob to the left of the image:

As I metioned before, TD13 was a very small cyclone, and as a consequence, it's managed to rapidly intensify. TD13 is now Tropical Storm Marco, with intensity now at 55kts. Indeed, there is a risk that Marco may become a hurricane before landfall early tomorrow. Recon have just investigated the system reporting the very much stronger winds than earlier. I certainly didn't expect to see a strong tropical storm in the Bay of Campeche this evening!

The East Pacific image has TS Marco and TS Norbert in shot. Look at the difference is size! Marco really is a very tiny storm!

How extrodinary! Possibly the smallest TS i've ever seen!Looks more like a MCS than a TS.

Indeed, the NHC said it could well be the smallest tropical cyclone on record! It truly is very tiny!

Marco has now made landfall as a 55kt tropical storm. Dissipation will be rapid due to the size of the storm, as the rugged terrain quickly tears apart the small LLC. A very interesting storm, will report back if anything is confirmed about it actually being a record braker for how small it is.

Shame it wasn't out in the atlantic to see it become a hurricane. Would love to have seen the changes in it.

So small I can't even see it on the posted images. I reckon it's a Radar glitch in reality. :):)
