Headline: Hydrologic Outlook issued May 10 at 3:45PM MDT by NWS Billings MT
Description: ESFBYZ

Warm temperatures reaching 10 to 20 degrees above normal will enhance
snowmelt in the mountains this week, resulting in significantly
higher flows on area waterways. Flooding is not expected at this time
due to marginal remaining snowpack in the middle elevations between
6000 and 8000 feet. Rivers such as the Yellowstone and Clarks Fork of
the Yellowstone are forecast to see flows double the current flows by
the end of the week.

Smaller streams and creeks flowing out of the mountains will
experience rises first this week, with larger rivers and streams
further downstream seeing increases by the end of the week.

Those with interests along foothills waterways should be prepared for
higher water levels this week, and move property and livestock away
from rivers, streams, and low lying areas.

Runoff may fill culverts, ditches, and storm drains causing water to
flow over foothills roadways potentially causing damage. Do not drive
over flooded roadways, Turn Around Don't Drown.

Recreationists in the mountains and foothills should be prepared for
changing conditions and use extra caution when near waterways. Flows
will be faster, and the water is very cold.

Stay tuned to the forecast. Please report any flooding to local law
enforcement and have them relay the report to the National Weather
Service.
