219-kt peak wind would be the highest wind value a dropsonde has ever recorded, ahead of 215-kt value in Super Typhoon Megi in 2010 & the 210 kt recorded just yesterday in #Hurricane #Melissa.
Still needs to be validated… so this data is preliminary.

This is hands down the most extraordinary dropsonde in Atlantic recon history.

#Melissa has made landfall in #Jamaica, and has preliminarily tied the record for the lowest pressure of any landfalling hurricane in Atlantic history: 892 mb. That was last observed 90 years ago with the 1935 Labor Day hurricane.
The storm does not look like it even notices Jamaica being there.

The worst possible scenario for Jamaica came true: climate-fueled hurricane #Melissa just made landfall at its strongest.
Maximum sustained winds of 295 km/h (185 mph) and an
estimated minimum central pressure of 892 mb (26.34 inches).

Warm oceans are oceans that remove less carbon from the atmosphere. During marine heatwaves, more organic material might be produced, but it doesn't get to the seafloor; it sort of gets stuck in the water, and all that carbon gets respired. 🧪🌊
