Tropical Storm Priscilla Discussion Number   1
Based on these data, advisories are 
being initiated on Tropical Storm Priscilla, with an estimated 
intensity of 40 kt.
bought Ṁ300 YES

just formed

850mb RVOR already quite a bit above 100 per CIMSS

mid level and up shows 500mb is a bit disorganized from shear over the southern part of the system.

Last HY-2B pass shows a robust surface low ...

Some disagreement in the DVTS fixes about its strength though (SAB 12Z indicated a weaker center with 1.5/1.5 TAFB 12Z with 2.0/2.0). Based on the HY-2B pass and the ample convection I think we should expect some increase in winds for the METOP-B pass. Latest MTCSWA has been oscillating between 32-34kt for last ~9 hours. D-PRINT at 30 kt.

There should be a fair partial METOP-B pass in about 15 mins that should cover the center ... should be available for the 21Z advisory

Satellite: METOP-B

Pass: Descending

Time: 2025-10-04T16:46:00Z

Swath 1 of 1

Multiple gale force wind vectors in the KNMI vectors.

Looks good for the 21Z advisory based on this…

TAFB 18Z DVTS came in at 2.5/2.5

SAB 18Z at 2.0/2.0.

With the METOP-B 25km NOAA wind vectors showing at least 2 34kt+ wind vectors that aren't rain-flagged, it seems likely to me they will classify it for the 21Z advisory as Priscilla.
