Heavy Spring Storm Triggers Flood Warnings Across Western Montana

Overview

• Multiple National Weather Service flood alerts remain in effect across western Montana, including areal warnings for valley low spots and a flood watch for the Clark Fork River.
• The storm has delivered widespread rainfall of roughly 1–3 inches in many locations, producing localized ponding and minor flooding in low‑lying areas.
• The Clark Fork River is forecast to crest just above 7.0 feet, which meteorologists say stays below the 7.5‑foot minor‑flood threshold but keeps water levels elevated through midweek.
• Steep slopes around Glacier National Park and mountain streams are at heightened risk for rock slides, mudflows and flash flooding because heavy rain falling on remaining snowpack accelerates runoff.
• Forecasts call for additional light to moderate rain through midweek, a brief dry break, and a renewed chance of showers and a few strong storms later in the week that could prolong travel and outdoor hazards.
