Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Campers and hikers should avoid flooded trail crossings. If camping at a site along or near the banks of rivers or streams, move away from those locations and seek higher ground. Trails in hilly terrain can quickly become unstable during or shortly after heavy rainfall. Visitors to area waterfalls should expect snow and ice covered trails and be careful around rivers that will have slippery rocks, cliffs, and strong currents.
