December 2010 - “A complete reanalysis was conducted for the years of 1926 to 1930. All 29 tropical storms and hurricanes were revised in their tracks and intensities. Four new tropical storm were discovered and added into HURDAT. Most significant hurricanes of this era were the 1926 Category 4 hurricane in the Bahamas, the 1926 Category 4 Great Miami hurricane, the 1926 Category 4 Hurricane in Cuba (these three major hurricanes in 1926 were separate systems), the 1928 Category 5 San Felipe (Puerto Rico)/Category 4 Lake Okeechobee hurricane, the 1929 Category 4 hurricane in the Bahamas, and the 1930 Category 4 hurricane in the Dominican Republic."

I read through it, and found it somewhat lacking, compared to previous re-analyses. It seems like the Weather Bureau really did do a good job catching all of the storms.

Here is the breakdown by season
1926 - 11/8/6 (no change, although #3 gained MH and #8 lost it) - one thing remains, there were indeed two simultaneous C4 hurricanes (mentioned back when Igor and Julia did the same feat)
1927 - 8/4/1 (previous was 7/4/2 - #4 lost MH status, new fish hurricane)
1928 - 6/4/1 (no change, #4 remains C5 hurricane at PR landfall)
1929 - 5/3/1 (previous was 3/3/1 - new TS near Bermuda, and old #3 was split into two storms; also, old #2 was upped to 135 kt)
1930 - 3/2/2 (up from 2/2/1 - new GOM non-landfalling TS, and #1 reached MH status)

The next set should be interesting. We should gain at least one Cat 5 in the early 1930s.

Interesting study of the 1944-53 period storms. Some notables in there:

1944 Northeast hurricane - Cat 2 at landfall

New 1944 storm - Hit Portugal as a TS

1945 Texas hurricane - Cat 2 at landfall (currently listed as Cat 4)

1947 Fort Lauderdale hurricane - Landfall intensity 115 kt (currently listed at 135 kt), peak intensity drops from Cat 5 to Cat 4

1949 Everglades area hurricane - Cat 4 at landfall (currently listed as Cat 3)

1950 Dog and 1951 Easy - Neither were Cat 5 it appears

1950 King - Cat 4 at landfall (currently listed as Cat 3)

1950 Mike was INDEED a TS, and the delisting may have been an error.

Also, over water, it is believed Carol of 1953 was a Category 5 hurricane. I would disagree, since 929mb at the latitude it was it does not support Cat 5 by any means.

Awesome I always love to see Hurdat getting closer.

I just thought I'd note that wasn't a HURDAT affiliated research project, so it won't be for years for that era to be analyzed. Basically, it's completely unofficial, albeit a good read.

If that report becomes official, the 1949-50 period would have 32 storms (16 in each) and would be very comparable with recent back-to-back seasons.

I was going to let you guys know once everything was up.

I saw a map of the Texas 1945 Hurricane. It was a rather small hurricane. I am curious about 1941 and 1942 because two hurricanes were re-classified as major hurricane upon landfall on Texas.

Also from that link.
1950 has 6 major hurricanes, not 8 and ACE is 211.
If Katrina was in the 1940s, it would not be a Category 5 hurricane. 920 mb is 132 knots north of 25N. However, it had 110 knots due to its massive size.
Same applies with Rita and Wilma.

I would not be surprised if more storms formed, especially in the open Atlantic.

In addition, there was a Basin Crosser in 1945 (Storm 10) as well as a TS forming on January 2, 1951.

About the historic comparison to modern Cat 5 study, there is a fair amount of uncertainty. It is certainly possible that ships would have been more prone to entering storms and data could have been recovered (nowadays they have warning to avoid them if at all possible). It is also possible that barometers may not have existed in places they do now. Given the density of shipping lanes, some central or near-central pressures may have been recorded. The Mitch assumption was based on the land station that was closed in the 1980s, and that it survived to catch the eye.

The most likely pressures to have been reported IMO would have been Ivan (a case could be made that it was a Cat 5 simply on the wind data due to the Cayman Islands report and likelihood that stronger winds existed elsewhere, which it did) and Dean (it was fairly close to or on land when it was a Cat 5, so ships would likely have been in the areas).

The LEAST likely to have been reported IMO would have been Wilma (the core was so tight there was almost no way a ship could get in there to get the 882 or anything near it) and Emily (its pressure was quite high and it was so short-lived at Cat 5 only the Recon wind data got it that).

Isabel would have dropped all the way to a peak of 115 kt (or less) based on data outside of Recon and Dvorak estimates. Given the fact that Isabel was in areas not filled with ships until it weakened, it would have been difficult to get the intensity, but certainly not impossible given its huge eye.
