Tropical Storm Genevieve Discussion Number  28
NWS National Hurricane Center Miami FL       EP072026
500 PM HST Thu Jul 30 2026
 
Genevieve is now a tropical storm, and the cyclone remains on a 
weakening trend.  Visible and infrared satellite imagery shows 
that the convection in the inner core continues to degrade. Water 
vapor imagery also shows that some dry air has made progress into 
the inner core of the storm as well. In addition, the objective 
intensity estimates continue to trend downward, in the range of 
50-65 kt.  The most recent current intensity estimate from TAFB is 
4.0/65 kt but the T-number has decreased to 3.5/55 kt.  Based on the 
downward trend presented by both the satellite imagery and the 
various subjective and objective estimates, the advisory intensity 
is reduced to 60 kt.
 
Genevieve continues to move along a west-northwestward heading
today, guided by a strengthening ridge to the north. This general
motion will prevail over the next 72 h or so. By early next week, a
strong upper-level trough will advance toward the western U.S. and
evolve into a cutoff low, steering Genevieve toward the northwest
then north-northwest. Only slight adjustments have been made to the
track based on the latest guidance and the position of the storm at
this time. The track forecast continues to be in good agreement with
the consensus of the guidance.
 
The tropical storm has moved into cooler waters and is experiencing
dry mid-level air and less favorable upper-level winds. These
factors will lead to further steady weakening over the next several
days. Global model guidance suggests that Genevieve may struggle to
produce organized deep convection this weekend, and the forecast
calls for the system to become post-tropical by 72 h, and a remnant
low early next week. The new forecast intensity remains very similar
to the previous advisory, and is near the middle of the consensus
guidance.
