ESFBYZ Expect very warm temperatures through Monday. Enhanced snowmelt in the mountains will continue to increase flows on area rivers and streams through the first part of the week. While flooding is not anticipated on larger rivers and streams, there is a chance that some smaller streams could reach bankfull in and near the foothills, producing minor flooding. At the very least, stream flows will be much higher with the increased snowmelt. Water rises will occur first on small streams flowing out of the foothills, eventually arriving on larger rivers and streams. The rate and magnitude of the water rises will be determined by how warm temperatures get over the mountains, as well as whether temperatures remain above freezing overnight. Also, there is potential for significant widespread precipitation from Tuesday night to Thursday. Snow is expected to fall above 7000 feet, ending the high elevation snow melt for the time being, but rain at lower elevations may cause additional rises on some streams and rivers. There is still uncertainty regarding exact precipitation amounts, and we urge people to monitor the forecast over the coming days. For those living near waterways, this may be the last chance to finalize preparations for runoff season. Move any livestock and equipment to higher ground away from waterways. Any stream bank stabilization activities should be completed as soon as possible. For those planning recreation activities on or near waterways, be prepared for changing conditions and significantly higher flows. Erosion will also increase as stream flows increase, making streambanks unstable. Please stay well away from streambanks when water is running fast, and be especially vigilant with children. Erosion will undercut the bank and can break off taking the bank and anyone standing on it into a very cold raging current. Stay tuned to the forecast for any watches, advisories, or warnings. Please report any flooding to local law enforcement and have them relay the report to the National Weather Service.
