Y'all - this is literally insane. I am pretty sure that I have never seen automated satellite intensity estimates this high on an Atlantic hurricane. Dvorak T-numbers approaching 8.5 are almost always with west Pac supertyphoons. Graphic from UW-CIMSS.

Last week I got to visit CIMSS. If you’ve been to UW-Madison you’ve seen it: the tower with the satellite dishes on top.
But its life-saving forecasting & data collection are at risk from NOAA cuts.

The Advanced Dvorak Technique (ADT) satellite-derived intensity estimate peaked at 185 knots for #Melissa -- which, according to the developer at CIMSS, is the highest value to date for any tropical cyclone.

Supertyphoon Bavi looking rather incredible (and threatening) as it moves toward the Marianas. Automated satellite estimate has it about 145 kt per CIMSS.

A comprehensive article of what is at stake with the current budget proposed by the DoC ➡️ NOAA.
Nearly every aspect of what we do at NHC has been touched by NOAA Research in one facet or another to our benefit.
#AOML, #CIMSS, #CIRA, #CIMAS all play key roles & losing any of them would be horrific.

The other day I posted a list of NOAA Research contributions to forecast operations at NHC. I decided to add a little flesh to that list with this Substack post.

Hurricane Forecasting and the FY-26 NOAA Budget Proposal
If NOAA were really interested in providing the American public with “gold-standard, cutting-edge data, models, and forecasts”, they wouldn’t be trying to get rid of the people who make it happen.

The tiny eye from #Erin is messing with objective estimate. I re-ran some D-PRINT intensity estimates with the ADT centering position and saw 25kt increases! Now much closer to aircraft data and best track. Definitely love my colleagues at CIMSS.
Can we get some microwave overpasses please??

Dorian was the last Cat 5 Atlantic landfall and the strongest landfalling Atlantic hurricane in the modern era, tied with the 1935 Labor Day hurricane.
