Hi Map

Attention to the West Coast for Atmospheric River, finally again.

Attached are a few images or you can visit Jay Cordeira's website
at Plymouth State for nice loops to see the 3 rivers.

We still have too much deterministic approach but the water vapor
transport shows us visually where to focus on heavy precipitation potential.
The terrain can be easy as its fixed and modeled very well in high resolution
NWP. I attached my favorite CANSAC WRF at 2 km and GFS/NAM/ECMWF.
You can see there are some north/south differences. I have found that GFS 
(even the 27 km version) has done well with maximum amounts in the favored
orographic regions such as Feather Basin.
