Moisture from the eastern Pacific Ocean and the Gulf of California moved northward around the periphery of high pressure centered over the Four-Corners region of the Rockies the 24th into the 25th. This moisture, coupled with the weak flow and increased instability in the lower to middle portions of the atmosphere, resulted in storms producing heavy rains.
