Overview

• Environment and Climate Change Canada has issued rainfall warnings for Metro Vancouver, Howe Sound and the Sunshine Coast with up to 80 mm expected at higher elevations through Friday night.
• B.C.’s River Forecast Centre elevated a high streamflow advisory across the South Coast as rivers are forecast to rise rapidly, posing washout and recreation risks.
• National Weather Service offices forecast 3–5 inches of rain in mountain zones and 0.5–1.5 inches in lowlands, with peak precipitation from Friday into Saturday and drier skies returning by Sunday.
• Forecasters say the heavy downpour will offer short-term drought and wildfire relief but will not end the fire season or fully alleviate long-term dry conditions.
• A revitalized North American Monsoon will heighten thunderstorms and wetting rain across the Desert Southwest, with Phoenix potentially seeing its first measurable rainfall in over six weeks, while the Bay Area braces for cooler, gusty but mostly dry weather.
