The Euro is surprisingly aggressive with this one and bombs it out to 960-965 mbar. However, like 94W, there is quite a good agreement between the global models on this one, with the GFS, CMC, and NAVGEM bringing it to Cat 1-2 intensity by early next week. It should be noted that SSTs and OHC between the equator and 10-15 S are high enough to support a maximum potential intensity of <900 mbar and >150 kt, if other environmental factors are favorable.

[aspen]

There continues to be strong agreement among the global models on 90P’s development, which is expected to occur within the next 24-48 hours. Both the GFS and Euro bomb it out to 960-965 mbar, and the CMC is not far behind.

The currently available name for the system, and the first in the 2019-2020 list, is Rita. I’m surprised it did not get a global retirement after 2005.

SYSTEM AS IT MOVE SOUTHWARDS.
POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE IN THE
NEXT 24 TO 48 HOURS IS MODERATE TO HIGH.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 7.6S 166.0E TO 9.8S 169.7E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT
IMAGERY AT 230000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.7S 166.3E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 07
KNOTS.
2. REMARKS:
AN AREA OF CONVECTION (INVEST 90P), PREVIOUSLY LOCATED NEAR 7.1S
163.4E, IS NOW LOCATED NEAR 7.7S 166.3E, APPROXIMATELY 380 NM EAST-
NORTHEAST OF HONIARA, SOLOMON ISLANDS. ANIMATED MULTISPECTRAL
IMAGERY DEPICTS CONVECTIVE BANDING WRAPPING OVER A LOW LEVEL
CIRCULATION CENTER EVIDENT BY A 22229Z METOP-B 89GHZ SATELLITE
IMAGE. THE ENVIRONMENT PROVIDES FOR MODERATE DEVELOPMENT WITH WARM
(29-30C) SEA SURFACE TEMPERATURES, LOW TO MODERATE (10-20KTS)
VERTICAL WIND SHEAR, AND DIFFLUENCE ALOFT. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT DEVELOPMENT INTO WARNING STATUS IS LIKELY BY TAU 24.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.

Models are more bearish everytime with this, why there is still not a significant system in southern hemisphere already this season?

[aspen]

Now TC 1P, but because the center formed further south than expected, it probably won’t strengthen much.

It's still early in the season for the Southern Hemisphere. Give it more time. Most of the intense systems occur from February to April.

THIS IS THE FIRST WARNING FOR THIS SYSTEM.

[aspen]

Upgraded to 55 kt and expected to peak at 65 kt later today.

[aspen]

Convection has warmed due to the arrival of daytime, but an eye is starting to form, and there’s a chance of this becoming much stronger at diurnal max.

That is what I am wondering too.
