The national average cost for diesel has fallen two consecutive weeks, according to the U.S. Department of Energy.

The national average for the week ending Nov. 7 was $2.698 per gallon, down 17.8 cents from the week before. That’s still a little bit far from pre-Katrina levels, though it’s getting closer. The national average for the week before Katrina hit was $2.59 per gallon.

Though all regions were reporting prices below $3 per gallon, the highest was the Rocky Mountain region, at $2.907 per gallon.

The biggest drop was in the Midwest, which saw prices fall 23.6 cents to $2.671 per gallon.

The lowest average was found in the Lower Atlantic region, which posted $2.608 per gallon. The Central Atlantic came in at $2.755 per gallon, and New England was at $2.744 per gallon. Overall, the East Coast average was $2.657 per gallon.

California, which once consistently had the highest prices in the country, posted an average of $2.797 per gallon. The rest of the West Coast, meanwhile, came in at $2.821 per gallon.

The hurricane-stricken Gulf Coast region posted an average of $2.679 per gallon.
