California Braces for Deluge: Pineapple Express Unleashed
21 Dec, 2025
Summary
- Atmospheric rivers are shifting south, targeting California with heavy rain.
- Northern California expects substantial rainfall, risking floods and mudslides.
- California is now drought-free for the first time since July 2024.
Persistent atmospheric rivers have caused extensive flooding in British Columbia, but the most active weather systems are now moving south across the international border. These powerful storms, a specific type known as a Pineapple Express, are poised to bring substantial rainfall to California.
Northern California is expected to experience heavy rain for the upcoming week, with potential for flooding and mudslides, especially in the Sierra Nevada where over 500 mm could fall. Cities like Sacramento and San Francisco are anticipating significant precipitation totals, vital for replenishing water reserves.
The article notes that California has been declared drought-free this month, a significant positive development. While the rainfall is beneficial for water resources, forecasters hope for snow at higher elevations to further bolster water supplies for the dry months ahead and the next wildfire season.
