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.

City by City Forecast:

BOZEMAN: LOW: 45°; HIGH WEDNESDAY: 70°. Moderate rainfall continues for the Bozeman/Belgrade areas through the early evening hours. There is a slight chance for a few thunderstorms as well but overall more of the same cool and wet. We could pickup a half an inch or more of rain for today. Drier air begins to move into the region Wednesday.

BUTTE: LOW: 44°; HIGH WEDNESDAY: 69°. Rain showers continue for Butte through about midnight with around a half an inch or more possible for today. Showers will be ending overnight and look for patchy valley fog by early Wednesday morning. Drier weather will build over Butte Wednesday into Thursday morning.

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.

WEST YELLOWSTONE: LOW: 38°; HIGH WEDNESDAY: 63°. Cool and wet weather pattern will continue over West Yellowstone heading into tonight. The current storm system will begin to push away from West Yellowstone tomorrow and a short lived drier weather pattern is likely for a few days.


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.
