Impressive microwave pass confirming the last recon message which showed a closed eyewall.

Can you tell me what were other times that a hurricane formed in that general area after start of October?

Thanks

Hurricane Isaias Discussion Number 8
NWS National Hurricane Center Miami FL AL092026
1000 AM CDT Thu Oct 08 2026

Isaias is strengthening in an environment of moderate vertical wind 
shear. Observations from an Air Force Hurricane Hunter aircraft 
indicate that the central pressure continues to fall and the 
maximum winds are now near 75 kt. The center of the hurricane is 
near the southwestern side of a Central Dense Overcast feature, and 
some convective banding features are evident over the eastern 
portion of the circulation. Additional aircraft reconnaissance 
missions are scheduled for today, tonight, and Friday, so we will 
have close monitoring of the intensity of the system up until 
landfall.

Center fixes from the Hurricane Hunters indicate that Isais 
continues on a generally east-northward track with an initial 
motion of about 060/9 kt. During the next 36 hours, the hurricane 
should gradually turn toward the northeast and north as it moves 
between a ridge extending from the Bahamas across the Florida 
Peninsula and a zonally-oriented mid-level trough near the 
northwestern Gulf coast. On the forecast track, the center of the 
hurricane is forecast to move across the east-central to 
northeastern Gulf coast in 36-42 hours. Thereafter, the weakening 
cyclone should move over the southeastern United States bringing 
strong winds well inland. The track guidance has not changed much 
for this advisory cycle and the official forecast is similar to that 
of the previous advisory.

The intensity forecast up to landfall is somewhat challenging. 
On the one hand, the hurricane should move over waters of high 
oceanic heat content and within a fairly moist air mass through 
tomorrow. On the other hand, the SHIPS model input parameters show 
a significant increase in vertical wind shear, particularly when 
Isais nears the coast. Regarding, the shorter-term intensity 
forecast, a recent WSFM microwave satellite image at 37 GHz 
frequency shows a closed ring around the eye. This is typically a 
harbinger of rapid intensification. The 12-hour forecast does show 
a relatively large increase in strength, but in view of the 
expected stronger shear in 24-36 hours, some decrease in intensity 
is indicated as Isaias approaches the coast. Regardless, Isaias is 
expected to remain a dangerous hurricane through landfall, and 
gusty winds are expected well inland after landfall given the 
anticipated expansion of the wind field and accelerating forward 
speed of the storm.
