A dangerous winter storm is still hammering Lake and Mendocino counties today, with strong winds, heavy rain, and flooding concerns lasting into Christmas Day. Forecasters warn wind gusts could top 70 miles an hour, especially overnight, increasing the chances of falling trees, power outages, and blocked roads. This second round of the storm is expected to linger longer, making travel risky well into tomorrow. Officials urge drivers to stay off flooded roads, warning that swift water can easily sweep vehicles away. Anyone needing shelter from the storm can head to the resiliency center in Lakeport.
