Tropical Storm Gonzalo Discussion Number   5
NWS National Hurricane Center Miami FL       AL072026
200 AM CVT Sat Sep 26 2026
 
ASCAT-C data valid near 2230 UTC indicated that Gonzalo's
circulation has become poorly defined. At that time, the center of
Gonzalo was severely stretched by about 100 miles from southwest to
northeast. Although the ASCAT did not fully sample the area where
convection associated with Gonzalo is strongest, it did indicate
that the winds have generally decreased since yesterday. Based on
these data and the latest TAFB Dvorak fix, the intensity has been
lowered to 40 kt. It is worth noting that if current trends
continue and the center does not re-form under the convection,
Gonzalo could dissipate later this morning.

Gonzalo still appears to be moving northward, and should continue 
on this track for the next day or so, though the track could jump 
to the northeast temporarily if the center re-forms nearer the deep 
convection. Regardless, models indicate that the remaining 
convection should become disorganized within the next 24 h, which 
would cause the cyclone to become post-tropical. Given the 
environment that Gonzalo is moving into, which will consist of 
increasing shear and cool SSTs, this seems likely. Once it becomes a 
shallow cyclone, the remnants of Gonzalo are expected to meander 
slowly to the north of the Cabo Verde Islands for several days 
before dissipating near the middle of next week.
