Tokage is back

It'd be pretty bummer if this gets Hinnamnor first, unless this becomes a cat 5.

Sure looks like 90W is a TS now. Scatterometer 5 hrs ago indicated 35 kts. A lot better looking now.

Looks like JMA woke up and called it a "TD". NOAA Dvorak at 00Z was 1.0. Better look again...

Given the quick organization of this storm so far, I suppose it's not impossible for 90W to reach typhoon status ...

It appears to have a short window for strengthening. Should begin weakening in 12-24 hours.

Too bad ASCAT missed it. Looks like 45-50kts now.

Seeing the JTWC issue a special warning would be "historic" feat now

[StormTracker89]

Tight troughing no LLC? Moderate EQUATORWARD outflow and 20kt of VWS? Seriously what are you guys looking at? 2130Z scat pass showed a very small but evident LLCC with an asymmetric wind field with 35kt or more in the eastern hemisphere. A very quick look at CIMSS storm-centered imagery shows 10kt or less of VWS and very good divergent POLEWARD outflow. There is some equatorward outflow further to the east sure, but the primary outflow mechanism is poleward on the east side of the TUTT. What is this TUTT in a favorable position "offsetting" exactly? This is a FAVORABLE or VERY FAVORABLE environment, not marginal. This is the same exact scenario from last week with 99W/11W. By 0430Z its starting to a banding eye even. JTWC going to have to play catch up, which it appears they are right now renumbering to 12W already.

SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 90W)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 24.9N 150.0E TO 29.4N 143.0E
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 25 TO 30 KNOTS. METSAT
IMAGERY AT 280000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 24.8N 150.0E. THE SYSTEM IS MOVING NORTH-NORTHWESTWARD AT 10
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR
24.1N 151.3E IS NOW LOCATED NEAR 24.7N 149.8E, APPROXIMATELY 461 NM
EAST OF IWO TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS A
MORE CONSOLIDATED AREA OF CONVECTION WRAPPING INTO A MID-LEVEL
ROTATION. HOWEVER, THIS SYSTEM IS VOID OF A LOW LEVEL CIRCULATION
CENTER AND HAS A WEAK BUT TIGHT TROUGHING ASSOCIATED WITH A WAVE
PROPAGATING NORTHWESTWARD. THIS TIGHT TROUGH IS EVIDENT ON THE 272330Z
PARTIAL ASCAT-C PASS. ANALYSIS REVEALS A MARGINALLY FAVORABLE
ENVIRONMENT FOR DEVELOPMENT WITH MODERATE EQUATORWARD DIVERGENCE ALOFT,
LOW TO MODERATE (10-20KT) VERTICAL WIND SHEAR, AND WARM (30-31C) SEA
SURFACE TEMPERATURES OFFSET BY A TUTT CELL TO THE WEST-NORTHWEST.
GLOBAL MODELS PREDICT A MODEST INTENSIFICATION AS IT TRACKS NORTH-
NORTHWESTWARD OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
290400Z.

Looks like that's exactly what is happening.

New towers going up and wrapping around the center, might be starting to build a core... how in the world has JTWC not initiated warnings on this yet? My goodness

[Landy]

... this is an invest?

[weeniepatrol]

Uhh hello WAKE UP jtwc

[InfernoFlameCat]

Imagine if this was in the Atlantic and wasn't warned. like how do they think this is still an invest? maybe they went to sleep for the night
