Hydrologic Outlook

Prolonged Rain & Runoff Expected thru Tuesday AM

Localized Heavy Showers Tuesday

Heads up, Northwest Montana! 🌧️ We are tracking a prolonged rain and runoff event targeting Flathead, Lake, Lincoln, Missoula and Sanders counties this Sunday and Monday (June 28-29). With 1 to 3 inches of rain expected in the valleys and 2 to 4 inches in the mountains, we are closely monitoring the threat of saturated soils, rapid water rises on streams and creeks, and rockslides in steep terrain. What you need to know: 🏕️ Camping this weekend? Be extremely mindful of where you park your RV or pitch your tent. Avoid setting up right on the water's edge, as streams and reservoirs could rise rapidly and flood your site. 🏡 Take some time today to clear your gutters and culverts in flood-prone areas. 🚗 If you travel through the mountains, be on high alert for falling rocks and debris. NEVER drive through standing water on roadways! Stay safe and monitor www.weather.gov/missoula for the latest updates as this system moves in.
