[4] Precipitation runoff from Mount Hanover drains east to the Capilano River, and west to Howe Sound via Deeks Creek.

Mount Hanover is more notable for its steep rise above local terrain than for its absolute elevation.

Topographic relief is significant as the summit rises 1,748 meters (5,735 feet) above Howe Sound in five kilometers (3.1 miles).

[6] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall.

As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall.
