I live in the interior of British Columbia but drive frequently over the coast mountains to the Lower Mainland. The southwest coast of BC (and northern Washington) are subject to intense ‘rivers of moisture’ events in the fall, winter, and spring. During La Nina these events can become extreme, and make coast mountain driving a challenge: unstable snow pack, flooding, washouts, road closures. Knowing the state of ENSO has been very helpful with risk assessment when planning my trip timing and routes. Thank you for being here!
