Several rounds of showers and thunderstorms are forecast through the weekend. There is a high chance that many locations receive over 1 inch of rainfall which could result in localized flooding, especially near burn scars.
Weather pattern becomes more active starting tomorrow with chances for afternoon/evening thunderstorms arriving Thursday and Friday. Locally heavy rainfall is possible with storms each day, with a few strong storms possible Friday (mainly east of Billings). Widespread significant precipitation is in the forecast for the weekend.
Burn scars from wildfires increase the risk of debris flows, which can destroy homes in their paths. Be aware of your surroundings and stay Weather-Ready by having multiple ways to receive weather alerts. weather.gov/safety/flood
