Weather Alert in Montana
Hydrologic Outlook issued May 11 at 10:18AM MDT by NWS Great Falls MT
AREAS AFFECTED: Beaverhead, MT; Broadwater, MT; Cascade, MT; Fergus, MT; Gallatin, MT; Glacier, MT; Jefferson, MT; Judith Basin, MT; Lewis and Clark, MT; Madison, MT; Meagher, MT; Pondera, MT; Teton, MT
DESCRIPTION: ESFTFX Despite cooler temperatures expected this week, the recent string of warm daytime and mild overnight temperatures has spurred an increase in high elevation snowmelt, resulting in within bank rises on some creeks and upper tributary rivers near the mountains. Scattered precipitation through Monday may add to some localized runoff but widespread precipitation expected to develop across primarily central and southwest Montana Tuesday and Wednesday is likely to fall as snow at elevations where a lingering snowpack exists. Significant rises are not expected on larger rivers, but some creeks and small rivers in the mountains and adjacent foothills may reach bankful early this week and remain elevated. Some locations that are approaching bankful and bear watching include: Badger Creek in Glacier county, Belt Creek in Cascade county and the Gallatin River. 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.

Cumulus clouds are fluffy and textured with rounded tops, and
may have flat bottoms. The border of a cumulus cloud
is clearly defined, and can have the appearance of cotton or cauliflower.
Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall,
becoming cumulus congestus and possibly the even taller cumulonimbus clouds.
When cumulus clouds become taller, they have a greater chance of producing precipitation.

Evaporation is the process which returns water from the earth
back to the atmosphere, and is another crucial process in the water cycle.
Evaporation is the transformation of liquid into gas, and it happens because
molecules are excited by the application of energy and turn into vapor.
In order for water to evaporate it has to be on the surface of a body of water.
