DISCUSSION
-----------------------------------
The combination of moderate southerly vertical wind shear, cooler 
sea-surface temperatures (SST) near 26 deg C, and dry mid-level air 
has caused Genevieve to rapidly weaken over the past 24 hours.  Very 
little deep convection remains, and what convection there is has 
been displaced well to the northeast of the low-level center. An 
ASCAT-A scatterometer pass at 0428Z indicated one surface wind 
vector of 43 kt in the northeastern quadrant about 40 nmi from the 
center. Thus, the initial intensity has been lowered  to 45 kt. The 
34-kt wind radii have also been decreased in all quadrants based on 
the scatterometer data. Passive microwave imagery the scatterometer data indicate that 
Genevieve's center is southwest of the previous advisory track, and 
the initial motion is now 295/09 kt. The weakening cyclone and its 
remnants should continue to move west-northwestward to northwestward 
during the next few days, accompanied by a decrease in forward speed 
as the system weakens and becomes more vertically shallow. The 
decoupled remnant mid-level circulation and its attendant moisture 
plume, however, are expected to move northward today through Sunday, 
and move into the southwestern United States on Monday. On the 
forecast track, Genevieve should gradually move away from the Baja 
California coast throughout the forecast period.
