Flooding shut down some lanes of state Highway 87 near state Highway 85 in San Jose early Thursday morning, prompting authorities to urge drivers to avoid the area.
Around 5:10 a.m., the California Highway Patrol said two southbound lanes of Highway 87 north of Highway 85 were flooded, creating risky driving conditions. An estimated time for reopening was not immediately available.
Drivers were advised to seek alternate routes or use caution since the water on the roadway can be difficult to see and may cause vehicles to lose control.
Flooding also forced the closure of a portion of state Highway 24 in Orinda early Thursday morning as heavy rain continued to soak the Bay Area. That has since reopened.
A powerful storm system has brought periods of heavy rain and strong winds across the Bay Area. Forecasters have warned that high rain rates can quickly overwhelm roadways, leading to sudden flooding, especially in low-lying areas and near creeks.
Drivers are urged to avoid flooded roads, follow closures and detours, and use alternate routes when possible.
