A deep upper low pressure system dropped from the Pacific Northwest into the Great Basin during the morning of October 11.  This resulted in a period of strong winds from the late morning hours until the evening as a very strong pressure gradient developed.  Several stations reported wind gusts exceeding 58 mph with the strongest winds most noticeable on the Mojave Desert Slopes of the Tehachapi Mountains.  A few low impact indicator sites reported gusts exceeding 80 mph.  The winds diminished by the morning of October 12 as the low moved east of the Great Basin and pressure gradients relaxed.
