SATELLITE ANALYSIS BULLETIN
Issued at 0627 UTC on 18 OCTOBER 2026
Tropical Cyclone Wati 01F

180600 UTC

Located near 16.5S 162.1W

Analysis based on: Visible and EIR

Latitude Detection Sum: 12

Longitude Detection Sum: 10

Dvorak analysis: T2.5/2.5/S0.0/24HRS STT:S0.0/06HRS

A curved band analysis of the most recent EIR imagery produced a log spiral
extent of 0.5 and thus a DT of 2.5. The 24h pattern shows slight weakening and
a W- trend was applied for a MET of 2.0 and a PAT of 2.5. The overall result
was an FT/CI of 2.5. Prior to this, the CI had been 3.0 through the entire
period since the last bulletin yesterday.  

However, Dvorak intensity estimates are suspected of underestimating the
intensity of TC Wati. CIMSS objective intensity aids are broadly higher, though
they are perhaps influenced by what may have been a false eye that appeared in
the EIR imagery around 1800 UTC. In addition, earlier ASCAT-C scatterometry at
2040 UTC contained 45 kt winds, and SMOS imagery at 1656 UTC indicated at least
storm force winds. 

The next bulletin will be available 190630 UTC
