ESFBYZ Unseasonably warm temperatures this weekend into early next week will result in higher flows on area waterways through next week as the remaining high elevation snowpack melts. Flooding is not expected at this time. Rivers such as the Yellowstone and Clarks Fork of the Yellowstone, Stillwater, and Boulder are expected to see flows double the current rates by late in the week. Smaller streams and creeks flowing out of the mountains will see rises late this weekend into early next week, with larger rivers and streams further downstream seeing the strongest increases from Tuesday through Friday. Those with interests along foothills waterways should be prepared for higher water levels, and move property and livestock away from rivers, streams, and low lying areas. Recreationists in the mountains and foothills should be prepared for changing conditions and use extra caution when near waterways. Flows will be higher and faster, and the water is very cold. Cloudy water conditions during runoff can also hide submerged hazards. Keep children and pets away from the edge of fast flowing waterways. Stay tuned to the forecast. Please report any flooding to local law enforcement and have them relay the report to the National Weather Service.
