Tropical Storm Flossie Discussion Number  17
NWS National Hurricane Center Miami FL       EP062025
200 AM MST Thu Jul 03 2025
 
Flossie continues to rapidly weaken, with a recent ASCAT pass 
indicating instrument derived winds of only 40 to 45 kt north of 
the center. The cyclone’s structure has further degraded, with deep 
convection absent and the low-level circulation now fully exposed. 
Both subjective and objective satellite current intensity estimates 
reflect this weakening trend, and the initial intensity has been 
lowered to 50 kt based on a blend of these data.

The initial motion is 300/8 kt. Flossie continues to move along the 
southwestern edge of a mid-level ridge situated over northern 
Mexico. This general motion is expected to persist for the next 
couple of days. The updated forecast track is nearly unchanged from 
the previous advisory and remains close to the consensus guidance.

Continued weakening is anticipated as the system moves over cooler 
waters and remains embedded in a dry and stable environment. With no 
deep convection, Flossie is forecast to become a post-tropical 
remnant low later today, with dissipation expected by 60 hours, if 
not sooner.
