Key Impacts of the Storm
1. Rainfall After a Long Dry Spell
This storm marks the first measurable rain in some parts of Southern California in more than eight months. The region’s rainy season typically begins in October, but the current season has been unusually dry, increasing the importance of this rainfall for drought-affected areas.
2. Potential Flooding in Burn Areas
Recent wildfire burn scars are particularly at risk for flooding and debris flows. Residents in these areas are urged to take precautions, including using sandbags to protect their properties.
3. Snow in Mountain Communities
Snowfall will bring relief to water reservoirs and skiing destinations but may also cause hazardous travel conditions. Drivers heading to higher elevations should prepare for icy roads and carry chains.
What Residents Should Do
- Prepare for Rain and Snow:
- Secure outdoor furniture and other items that may be impacted by high winds or heavy rain.
- Use sandbags if you live in a flood-prone or burn-scar area.
- Plan for Travel Delays:
- Avoid driving through flooded roads.
- For mountain travel, check road conditions and pack winter essentials, including tire chains.
- Stay Informed:
- Monitor local weather updates and advisories.
- Follow alerts from agencies such as the National Weather Service and Los Angeles County Public Works.
Southern California’s first major storm in months is expected to bring much-needed rainfall and snow, but it also comes with risks, especially in wildfire burn areas and mountain communities. By preparing in advance and staying informed, residents can safely navigate the challenges this weather system may bring.
