The National Weather Service has issued a FLOOD WATCH for SW Montana East of the divide through Tuesday evening.
Flooding could develop as continued moderate to heavy rainfall is impacting our region. Smaller streams and creeks will be most likely to see increasing flows and possible flooding issues into this evening.
The National Weather Service has issued a FLOOD ADVISORY for the Butte/Blackfoot region through 9 pm tonight.
Moderate to heavy rainfall again today will continue to keep smaller streams and creeks running high and there is a potential for flooding through this evening.
One area of particular interest is Warm Spring Creek running through Anaconda and Cottonwood Creek running through Deer Lodge.

DILLON: LOW: 43°; HIGH WEDNESDAY: 69°. Rain showers and isolated thunderstorms wrapping around a slow moving upper level Low will keep Dillon cool and wet through midnight. Starting Wednesday a short lived mild and dry weather pattern will give us a welcome break from the current cool and wet weather pattern.

NEXT WEATHER MAKER:
Weak High pressure is building up into the pacific NW and northern Rockies tonight through Thursday. This should give the region a break with warming and drying. Unfortunately, the next weather maker will begin to drop into the pacific NW Thursday and bring an increasing chance for more wet weather for SW Montana Friday into Saturday.
