Nice to see it made it to (MFR) Tropical Cyclone strength, making it the first of its kind in the Southern Hemisphere so far this season. However, it looks like it weakening has already begun. Structure is already beginning to take a hit from renewed adverse conditions.

2.C COMMENTS:
T = 3.5 + CI = 4.5-
LOSS OF ORGANIZATION NOTED JUST BEFORE 06Z CONTINUED THIS AFTERNOON
WITH NET SIGNS OF WESTERN SECTOR SHEARING. THE SSMI PASS
F15 DE 1137Z (RECEIVED JUST AFTER SENDING THE FIRST MESSAGES OF 12Z)
CONFIRMS THE DECOUPLING BETWEEN MIDDLE TROPO TRAFFIC
LOWER LAYERS. WHEREAS WEAKENING ON THE
CONFIGURATION CLOUD JUST BEFORE 06Z AND THAT THE INERTIA
WIND FIELDS IS LOWER IN RELATION TO THE METHOD
OF DVORAK FOR THESE SMALL-SIZED SYSTEMS, ESTIMATED INTENSITY IS
LOWER TO 60 KT.
THE SSMI PASS SUGGESTS THAT THE PRESENT ESTIMATED POSITION IS A FEW TO
THE WEST (BUT HOWEVER UNDER THE UNCERTAINTY MARGIN OF 30 MN
ANNOUNCED). WITH A DIRECTORY FLOW THAT WAS ABLE, THE SYSTEM IS
NEW ON A PATHWAY IN SOUTH-EAST GENERAL DIRECTION
THE INFLUENCE OF A MEDIUM TROPOSPHERE RIDGE IN THE NORTHEAST AND
THALWEG RAISING SINCE THE LATITUDES AVERAGE. FROM
SUNDAY, CARLOS SHOULD RETURN BLOCKED BY THE PASSAGE OF ONE
CELL ANTICYCLONIC TO THE SOUTH. THE MODEL AGREEMENT ON THIS
TRAJECTORY IS RIGHT GOOD. AT THE END OF PERIOD, AT THE TIME OF THE HALF-TOUR,
DISPERSION BECOMES MORE IMPORTANT.
TOMORROW, THE IMPORTANT RISE OF VERTICAL SHEAR AND
INTERACTION BAROCLINE WITH THE ALTITUDE TALWEG ARRIVING BY THE SUDOUEST,
SHOULD GIVE POST-TROPICAL CHARACTERISTICS TO THE SYSTEM.
DURING THE WEEKEND, THE MODELS SHOW CARLOS UNDER THE
THALWEG OF ALTITUDE WHICH IS INSULATED IN CUT-OFF ABOVE THE
CIRCULATION, WHICH PROTECTS THE SHEAR SYSTEM. IN THIS
CONTEXT, CARLOS MAY TAKE A SUBTROPICAL STRUCTURE
FROM SUNDAY IN SE (RE) TROPICALIZING ON POTENTIAL WATERS
ENERGY HOWEVER LIMITED.

Re: SWIO: Severe Tropical Storm Carlos
I thought it was nice how Carlos became the first "Tropical Cyclone" rated system in the SHem this year. Finally...lol. The SHem is so dead, and who knows why. Carlos will weaken from here on out, and the SWIO probably doesn't look like it will produce another TC for a while (idk...haven't checked models). The Australian region and South Pacific are now basins to watch for as there are currently a lot of invests throughout the two basins.

Hurricanes are an amazing natural phenomena. While many are spiraling pits of evil that kill people or cause devastation, some are tame and stay clear of land.
