...Increased runoff likely once again this week across portions
of Central and Southwest Montana...

Temperatures this past weekend cooled some, which helped to slow
the rate of snowmelt to some extent. However, moderating
temperatures this week will lead to increasing snowmelt rates once
again, especially at low- and mid-elevations. In addition, there
is the potential for a decent precipitation event later this week,
especially across Southwest Montana south of Interstate 90. If
this does occur, it could enhance runoff rates locally, especially
in valley locations.

If confidence in the potential of flooding continues to increase,
Flood Watches or Advisories may be necessary, so stay tuned for
later updates. Regardless, those living in flood prone areas,
especially near fields and streams, are encouraged to prepare for
new or additional flooding through the week.

If flooding is observed, please report it to local law enforcement,
and ask them to pass it on to the National Weather Service in Great
