Impressive to have the eye still near 20ºC with eyewall replacement about to kick into full gear.

Sentinel-3 captured Mangkhut yesterday at 2253z. If we are lucky we may even get a Sentinel-2 pass over the eye of Mangkhut in the next few days. That would be a first for the Western Pacific...

I'm currently processing the raw satellite data myself (you can download the netCDF4 files via the Copernicus open access hub: https://scihub.copernicus.eu/) but it may also be possible to get at least a quick preview of the images by using the EO Browser: https://apps.sentinel-hub.com/eo-browser/

EDIT: Here is the direct link to Typhoon Mangkhut: https://apps.sentinel-hub.com/eo-browser/?lat=13.801&lng=135.271&zoom=8&time=2018-09-12&preset=CUSTOM&gain=0.3&datasource=Sentinel-3%20OLCI&layers=B09,B06,B02&evalscript=cmV0dXJuIFtCMDkqMi41LEIwNioyLjUsQjAyKjIuNV07

Concentric eyewalls now very distinct on microwave imagery.

Jebi^

Mangkhut^

Peak intensity of both storms so far per the Multiplatform Satellite Surface Wind Analysis; Mangkhut has beat Jebi, but no Meranti or Haiyan, yet.

OHC's when Haiyan made landfall:

Meranti Peak:

Forecast for Mangkhut:
Image

For Mangkhut, it would seem the eyewall replacement cycle won't damage it much; intensity hasn't gone down at all (actually, increased like Irma last year :eek: ). Barring the height of the tropopause, not sure if this storm has a limit to its intensity in 48 hours or so based on previous analogues, and the forecast wind shear.

Looks like a possible new world record forecast low pressure, but prob wayyyyy overcooked. I imagine this is what the hwrf would have shown if it were available when typhoon haiyan was out at sea.
