Weather Alert in Montana
Hydrologic Outlook issued May 9 at 3:54PM MDT by NWS Billings MT
AREAS AFFECTED: Big Horn, MT; Carbon, MT; Golden Valley, MT; Park, MT; Stillwater, MT; Sweet Grass, MT; Wheatland, MT; Yellowstone, MT; Sheridan, WY
DESCRIPTION: ESFBYZ Warm temperatures are forecast through early next week. This will enhance snowmelt across area mountains, resulting in a significant increase in flows on area rivers and streams by this weekend. 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. Any precipitation may also result in strong and sudden water rises. 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.

Next Topic: Evaporation
Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.

Next Topic: Fractus Clouds
Fog is technically a type of stratus cloud, which lies along the
ground and obscures visibility.
It is usually created when humidity in the air condenses into tiny water droplets.
Because of this, some places are more prone to foggy weather, such as regions
close to a body of water.
Fog is similar to mist; both are the appearance of water droplets suspended in
the air, but fog is the term applied to the condition when visibility is less than 1 km.
