"I'm wondering if the presence of the mountains can have an effect on the atmospheric ridges/troughs plus wind shear in the area?"
Ridges and troughs are extremely large atmospheric regions of high and low pressure respectively. The location and the pressure difference between high and low-pressure systems are what create the steering winds for tropical cyclones and are not affected by the mountains. Wind shear, one of the main things that destroy hurricanes, essentially by decapitating them, generally occurs above 20,000-feet and is not affected by the mountains.
