Billings, MT – Residents across southeastern Montana should prepare for a wet weekend, as the National Weather Service (NWS) warns of excessive rainfall and potential flash flooding beginning Friday afternoon and continuing through Saturday night.
According to the NWS in Billings, a slight chance for excessive rainfall exists over far southeastern Montana Friday evening, with locally heavy rain expected across most of the region. Forecast models indicate a 40–80% probability of receiving more than a half-inch of rainfall in many locations.
Communities most at risk include Miles City, Baker, Colstrip, Hardin, and Lame Deer, where rainfall totals could exceed 1 inch. The highest probabilities for heavy rain range from 63% in Hardin to 77% in Baker, raising concerns for localized flooding. Billings has a lower, but still notable, 41% chance of half an inch or more.
The NWS has issued a Level 2 threat assessment, meaning at least a 15% chance of flash flooding is possible in southeastern Montana. The greatest risk is expected from Friday afternoon through late tonight, with heavier rain likely to continue into early Sunday morning.
Officials caution drivers not to attempt crossing flooded roadways and urge residents to have multiple ways to receive weather alerts. Outdoor plans may be disrupted, as the heaviest rainfall is forecast overnight.
This storm system could cause delays in travel and temporary flooding in low-lying areas, especially where soils are already saturated.
