Dvorak estimates from the SSD page (SAB; http://www.ssd.noaa.gov/PS/TROP/positions.html) have now come into agreement with the other set (TAFB) that JTWC is using to obtain intensity estimates for Chaba at T7.5. Unfortunately, the TAFB estimates aren't available online (other than in discussions)...and the one person I knew at the NHC isn't there anymore, so no luck there.

Chaba is also moving out of radar range from Guam, but it's been an interesting two days of radar imagery, to say the least. It's still got a shot, but there will be debate even if it reaches T8.0 (and they correspondingly bump up the winds to 170kt/pressure down to 858mb) just because of the lack of actual obs inside the storm.

Satellite imagery (note: slow to load, even on high-speed connections) is available here - https://metoc.npmoc.navy.mil/jtwc/satshots/wp1904sams.jpg - or via the NASA GHCC site from their global mosaic.
