Updated inventory of cities/islands impacted in 2025 by named systems Melissa added 8 to the map

The Air Force & NOAA hurricane hunters conducted 33 missions into, and around, #Melissa. Additional information appears in the alternate text for the images.

As what is left of post-tropical cyclone Melissa moves rapidly off into the northern Atlantic east of Canada, we look back at the missions into Melissa as a tropical cyclone. The Air Force and NOAA hurricane hunters conducted 33 missions into, and around, Melissa. They surveyed the storm from the time it was a tropical storm and throughout its rapid intensification into one of the most intense tropical cyclones ever recorded. Its turbulence was so intense at times that multiple aircraft had to return early for safety to be inspected after passing through its intense eyewall. Melissa made landfall at its peak intensity in New Hope, Jamaica with sustained winds of 185 mph and a pressure of 892 millibars. By both metrics Melissa tied, in both sustained wind speed and lowest mean sea level pressure, as the most intense tropical cyclone to ever make landfall on record in the Atlantic. (tying the landfalling wind speed of Hurricane Dorian in 2019 in the Bahamas and tying the landfalling pressure of the Labor Day hurricane in 1935 in the Florida Keys) The hurricane hunters continued their missions into the storm as long as it remained a threat to land as a tropical cyclone. The storm also had impacts in Hispaniola, Cuba, the Bahamas and Bermuda before becoming extratropical and passing east of Newfoundland in Canada. (impacted areas include areas where it did not make landfall)

Map showing the missions by the Air Force and NOAA hurricane hunters into, and around, Melissa. White circle icons represent either the mean sea level pressure in millibars recorded by a dropsonde released from the plane or the estimated MSLP if that data was not available. This data comes from a vortex data message. In cases where the wind was not calm enough at the center, the actual pressure may be estimated to be lower and that pressure is not reflected on the icon.

Wind barbs represent the wind speed and direction from the 30 second flight level wind that is usually reported every 30 seconds in a high density observation. (HDOB message)

A dropsonde icon, pictured as a slender tube, is what is used to measure pressure, temperature and dew point as it falls from the aircraft. A dropsonde is released from the aircraft by a tube.

The Air Force used multiple Lockheed WC-130J Hercules aircraft while NOAA used a Lockheed WP-3D Orion to survey the storm and penetrate its eye. NOAA also used a Gulfstream IV-SP to sample around the storm.

2X increase in the most extreme hurrucanes!
Looking at every Cat 4 & 5 in the Atlantic since 1980 (reliable records/ data gathering) I broke the record into 2 equal parts.
1980-2002 and 2003-2025
The most recent period has more than double the number of most intense hurricanes in the Atlantic!…

Invest 98L to be named Melissa today at that point the Euro will be added. So far these are the best track performers suggesting this will go further west. At this time only a few ensemble members of all the models have this flirting with Florida. Will the GFS be right taking this over Hispaniola?

Blown away by Google DeepMind's performance this year. We'll see if it carries into 2026, but it's been just head and shoulders better than any other model trackwise this season, including the gold standard consensus guidance. Big win for the addition of LLMs 👏

James Franklin @franklinjamesl.bsky.social · 21d

With about 80% of the precincts reporting I've seen enough. GDMI - Google DeepMind is going to win the seat for best track model in 2025. The race for best intensity model is still too close to call, but GDMI is right there with the consensus and OFCL. Quite a remarkable campaign.

Bermuda to be hit tonight but could Imelda be major? Here is a video on the majors to impact Bermuda and what they did to this tiny island. www.youtube.com/watch?v=xR1p...

Big reason why I encourage people to visit www.hurricanecity.com is the mapping of the best performing models which yesterday a couple of best performers were showing a turn to the right .Today it's even more showing Humberto having a big influence on track.

who gets hit most after the height of hurricane season?

Jim Williams @hurricanecity.com · Sep 10

Height of hurricane season only matters when it comes to hits. This graph shows the 139 cities in the HC database and the time period most likely to be hit by a hurricane.

ICYMI, I have a unique perspective today on this 125th anniversary of the deadliest American hurricane.

The Eyewall @theeyewallwx.bsky.social · Sep 8

Today marks the 125th anniversary of the Great 1900 hurricane that devastated Galveston, the deadliest single weather event in American history. But it wasn’t inevitable. The decisions made before and after the 1900 storm and relevance of it today rings loudly if we’re listening.

125 years after the Great Galveston Hurricane, it still remains relevant if we're willing to listen

The lessons of 1900 may be more relevant than ever today

the GFS is slightly outperforming the EURO on Erin by 15 miles at 5 days but overall the CMC is performing the best.
