Can't speak to the NW part of the country, but the St. Louis refinery took a hit a while back and it has caused shortages in the Rocky Mountain area.
I would suspect that some diesel is being diverted from West Coast and upper Midwest to cover the shortage.
I drive a semi for a living and keep up with the various fuel quarks going on. The prices have risen in the upper midwest as well. I would suspect that fuel is being diverted from Northwest and Upper Midwest to cover the shortages in Colorado and Wyoming. I know that that the Governor of Colorado has suspended the hours of service regulations for fuel tanker drivers so as to get fuel into the area.
The Alaska crude problem has not been on long enough to be a substantial effect on the supply. Most of that crude is made into gasoline as it is of the light sweet variety that is best for that purpose. It will effect eventually, but the supply is good for now.
Keep in mind that ALL crude and refined product prices are the result of speculators just like grain and metals. It takes a while before events such as the Alaska shutdown to actually make an impact. But the specualators are quick to take advantage and bid the prices up.
Even though fuel is my primary cost of operation, I have taken the postition that the fuel prices are not effecting anyone. I witness drivers of both autos and large trucks continuing to drive like the price is less than a $1 per gallon, so I figure that the prices are not a problem with anyone. I am more interested in taking as much money home as I can so I have adjusted my driving to conserve. To each his own.
