Go Seahawks - that was certifiably insane.

An initial issue with AIGFS total accumulated precipitation plots has been fixed. Sorry about that!

The @NWSEMC released an AI version of the GFS model and its ensemble system, based on GraphCast. This is NOAA's first operational foray into the era of machine-learning based weather prediction. Plots for AIGFS are now available on Tropical Tidbits: https://t.co/ox7LmuONUH I

Hurricane #Melissa is now racing northeastward, and will pass west of #Bermuda tonight. Max winds are estimated at 105 mph, and Melissa will likely remain a Cat 2 hurricane near Bermuda. A Hurricane Warning is in effect for the island. By Friday night, Melissa will be

Just terrible to see the aftermath of Hurricane #Melissa's strike on #Jamaica. I hope most residents found adequate shelter. Wishing the island a quick recovery and rebuild.

Hurricane #Melissa has crossed #Cuba and is accelerating northeastward as a weaker, but still dangerous hurricane. The storm's core has been broadened, and thus could affect a wider swath of locations today. Hurricane Warnings are in effect for the central and southeastern

As Hurricane #Melissa reemerges over water north of #Jamaica, the next land area due to be impacted by the inner core is eastern #Cuba early tomorrow morning, which has already been receiving heavy rainfall. Although the NHC has set the current intensity of Melissa at 145mph, it

Data from the aircraft indeed indicated extreme turbulence, prompting a longer than usual loitering inside the eye after penetration. Hoping the crew is all safe and uninjured.

All-time eyewall dropsonde right here from Hurricane #Melissa. 219 kt instantaneous wind above the surface, with a mean value of 188 kt in the lowest 150 meters, roughly supporting the estimated 1-minute mean surface wind of 160 kt (185 mph)

173 kt (199 mph) flight-level wind on the outbound leg is the highest observed today

The @NOAA_HurrHunter plane is timing up a final pre-landfall eye penetration in Hurricane #Melissa.

The @53rdWRS aircraft did get a dropsonde off before leaving the eye of #Melissa. Estimated central pressure here would be ~892 mb.

The sun rises on Hurricane #Melissa as data from the @53rdWRS prompt @NHC_Atlantic to assess maximum winds at 180 mph with a central pressure of 896mb in this Category 5 hurricane. Storms at this extreme intensity rarely make landfall. Unfortunately, Melissa will shortly do so

Some of the last hurricane hunter aircraft data for the evening just measured a central pressure of 903 mb in #Melissa, the lowest so far. There are also continuing hints in the wind profile of a secondary wind maximum beginning to form (pink arrows), which could signal a coming

Hurricane #Melissa is continuing its "stall-and-turn" sequence that will see it begin moving NNE towards western #Jamaica overnight tonight. Unfortunately, Melissa remains a Cat 5 hurricane with no concrete signs of being disrupted in the short-term, and could potentially make
